To complete assembly you will need a Philips screwdriver (size PH0)
and a wrench (size M5; included in package).
Note: We suggest you assemble all components of the weather
station, including console in one location so you can easily test
functionality. After testing, place the outdoor sensor package in
the desired location. Note, however, that movement during
assembly, and movement after assembly can cause the rain
sensor to “falsely” register rain. It is therefore best if you do not
connect the console to any Internet services until you have
reset these false readings using the console. The errant values
may be hard to remove from Internet services if you do not
reset first.
Attention:





Follow suggested order for battery installation (outdoor sensor first,
console second)
Ensure batteries are installed with correct polarity (+/-)
Do not mix old and new batteries
Do not use rechargeable batteries
If outdoor temperature may go below 32F or 0C for prolonged
periods, Lithium based batteries are suggested over alkaline type
batteries for the outdoor sensor array

Table 2: Sensor assembly detailed items
6.1.1 Install U-bolts and metal plate
Installation of the U-bolts, which are in turn used to mount the sensor
package on a pole, requires installation of an included metal plate to
receive the U-bolt ends. The metal plate, visible in Figure 3 on the right
side, has four holes through which the ends of the two U-Bolts will fit.
The plate itself is inserted in a groove on the bottom of the unit
(opposite side of solar panel). Note that one side of the plate has a
straight edge (which goes into the groove), the other side is bent at a
90-degree angle and has a curved profile (which will end up “hugging”
the mounting pole). Once the metal plate is inserted, remove nuts from
the U-Bolts and insert both U-bolts through the respective holes of the
metal plate as shown in Figure 3.
11
Figure 3: U-Bolt installation
Loosely screw on the nuts on the ends of the U-bolts. You will tighten
these later during final mounting. Final assembly is shown in Figure 4.
Figure 4: U-Bolts and nuts installed
The plate and U-Bolts are not yet needed at this stage but doing this
now may help avoid damaging wind vane and wind speed cups later
on. Handling of the sensor package with wind vane and speed cups
installed to install these bolts is more difficult and more likely to lead to
damage.
6.1.2 Install wind vane
Push the wind vane onto the shaft on the top side of the sensor
package, until it goes no further, as shown on the left side in Figure 5.
Next, tighten the set screw, with a Philips screwdriver (size PH0), as
12
shown on the right side, until the wind vane cannot be removed from
the axle. Make sure the wind vane can rotate freely. The wind vane’s
movement has a small amount of friction, which is helpful in providing
steady wind direction measurements.
Figure 5: Wind vane installation diagram
6.1.3 Install wind speed cups
Push the wind speed cup assembly onto the shaft on the opposite side
of the wind vane, as shown in Figure 6 on the left side. Tighten the set
screw, with a Philips screwdriver (size PH0), as shown on the right
side. Make sure the cup assembly can rotate freely. There should be
no noticeable friction when it is turning.
Figure 6: Wind speed cup installation diagram
13
6.1.4 Install Batteries in sensor package
Open the battery compartment with a screwdriver and insert 2 AA
batteries in the battery compartment. The LED indicator on the back of
the sensor package (item 9) will turn on for four seconds and then flash
once every 16 seconds indicating sensor data transmission. If you did
not pay attention, you may have missed the initial indication. You can
always remove the batteries and start over, but if you see the flash
once every 16 seconds, everything should be OK.
Figure 7: Battery installation diagram
Note: If LED does not light up or is on permanently, make sure the
battery is inserted the correct way and inserted fully, starting
over if necessary. Do not install the batteries backwards as it
may permanently damage the outdoor sensor.
Note: We recommend Lithium batteries for cold weather climates, but
alkaline batteries are sufficient for most climates.
Rechargeable batteries have lower voltages and should never
be used.
6.1.5 Mount assembled outdoor sensor package
6.1.5.1 Before you mount
Before proceeding with the outdoor mounting detailed in this section,
you may want to skip to setup instructions in section 6.3 and onwards
first, while you keep the assembled outdoor sensor package nearby
(although preferably not closer than 5 ft. from the console). This will
14
make any troubleshooting and adjustments easier and avoids any
distance or interference related issues from the setup.
After setup is complete and everything is working, return here for
outdoor mounting. If issues show up after outdoor mounting they are
almost certainly related to distance, obstacles etc.
6.1.5.2 Mounting
Your package includes two U-Bolts, 4 nuts, and a metal mounting plate
for the U-Bolts, in addition to a small section of metal pipe. You can
attach this section of pipe to a permanent structure and then attach the
sensor package to it (see Figure 8), or you can use a longer section of
pipe if that works better for getting the sensor package in the desired
location. The U-Bolts will accommodate a pipe diameter of 1-2 inches.
Figure 8: Sensor package mounting diagram
The mounting plate will slide into a slot on the bottom of the sensor
package and then you can provisionally insert the U-Bolts from the
other side through the holes provided holes. Next place a nut on each
of the four ends of the U-Bolts and tighten by hand several turns so
they will not fall off.
Next prepare the mounting pipe in the desired location and make sure
it is vertical, or very close to it. Use a level if needed.
15
Finally, place the sensor package on top of the prepared mounting
pipe. The U-Bolts should be loose enough to allow this but loosen the
nuts as necessary. Once placed, hand tighten all four nuts, taking care
to do so evenly. Do not use a wrench yet!
Now you will need to align the whole package in the proper direction by
rotating it on top of the mounting pipe as needed. Locate the arrow
labeled “WEST” that you will find on top of the sensor package right
next to the light sensor, on the opposite side of the solar panel. You
must rotate the whole sensor package until this arrow points due west.
To achieve proper alignment, it is helpful to use a compass (many cell
phones have a compass application). Once rotated in the correct
orientation, lightly tighten the bolts a little more (use a wrench) to
prevent further rotation.
Note: The orientation to WEST is necessary for two reasons. The
most important one is to position the solar panel and light
sensor in the most advantageous position for recording solar
radiation and charging internal capacitors. Secondly it causes
a zero reading for wind direction to correspond to due NORTH,
as is customary. This orientation is correct for installations in
the northern hemisphere. If you are installing in the southern
hemisphere, the correct orientation to achieve the same
optimal positioning is to have the “WEST” arrow actually point
due EAST! This has the side effect, however, of lining up the 0
reading of the wind direction with SOUTH. This needs to be
corrected using a 180-degree offset in the calibration settings
(see section 7.2.7 on page 33).
Now look at the bubble level. The bubble should be fully inside the red
circle. If it is not, wind direction, speed, and rain readings may not
operate correctly or accurately. Adjust the mounting pipe as necessary.
If the bubble is close, but not quite inside the circle, and you cannot
adjust the mounting pipe, you may have to experiment with small
wooden or heavy cardboard shims between the sensor package and
16
the top of the mounting pole to achieve the desired result (this will
require loosening the bolts and some experimentation).
Make sure you check, and correct if necessary, the westerly
orientation as the final installation step, and now tighten the bolts with
a wrench. Do not over tighten, but make sure strong wind and/or rain
cannot move the sensor package.
Note: If you tested the full assembly indoors and then came back
here for instructions and mounted to sensor package outdoor
you may want to make some further adjustments on the
console. The transportation from indoor to outdoor and
handling of the sensor is likely to have “tripped” the rainfall
sensing bucket one or more times and consequently the
console may have registered rainfall that did not really exist.
You can use console functions to clear this from history. Doing
so is also important to avoid false registration of these readings
with weather services.
6.1.6 Reset Button and Transmitter LED
In the event the sensor array is not transmitting, reset the sensor array.
Using a bent-open paperclip, press and hold the RESET BUTTON
(see Figure 9) to affect a reset: the LED turns on while the RESET
button is depressed, and you can now let go. The LED should then
resume as normal, flashing approximately once every 16 seconds.
Figure 9: Reset button and Transmitter LED location

6.2 Best Practices for Wireless Communication
Wireless (RF) communication is susceptible to interference, distance,
walls and metal barriers. We recommend the following best practices
for trouble free wireless communication between the sensor package
and the console:




Electro-Magnetic Interference (EMI). Keep the console several
feet away from computer monitors and TVs.
Radio Frequency Interference (RFI). If you have other devices
operating on the same frequency band as your indoor and/or
outdoor sensors and experience intermittent communication
between sensor package and console, try turning off these other
devices for troubleshooting purposes. You may need to relocate
the transmitters or receivers to avoid the interference and establish
reliable communication. The frequencies used by the sensors are
one of (depending on your location): 433, 868, or 915 MHz (915
MHz for United States).
Line of Sight Rating. This device is rated at 300 feet line of sight
(under ideal circumstances; no interference, barriers or walls), but
in most real-world scenarios, including a wall or two, you will be
able to go about 100 feet.
Metal Barriers. Radio frequency will not pass through metal
barriers such as aluminum siding or metal wall framing. If you have
such metal barriers and experience communication problems, you
must change the placement of sensor package and or console.
The following table shows different transmission media and expected
signal strength reductions. Each “wall” or obstruction decreases the
transmission range by the factor shown below.

6.3.1 Initial Display Console Set Up
Immediately after power up (inserting batteries and/or power adapter),
the unit will turn on all segments of the LCD for 3 seconds and will then
display one or more messages on the bottom: firmware version, RF
frequency and sensor identifier. Then the unit will start to look for
reception of the outdoor sensor data which may take up to 3 minutes.
Once the signal has been found and registered, the unit will enter the
receive and display mode.

7 Operating the console
The console display contains 10 distinct information segments as well
as a message panel on the bottom left side.
The console operates in several different modes: normal, settings,
history, alarm, max/min, and calibration settings. Each mode is
explained in the following sections.
Any mode other than normal, can always be exited to return to normal
mode by depressing the “HISTORY” button briefly. Thirty seconds of
inactivity in any mode will also cause a return to normal mode.
7.1 Normal mode
Normal mode is the most often used mode. It is used to display most
current sensor information for quick inspection.
There are information segments for each separate sensor (10 totals),
such as temperature, pressure etc. Press LEFT, or RIGHT keys to
switch among different segments. The currently selected segment will
be marked with the arrow symbol .
The selected segment also determines the message(s) shown in the
message panel on the bottom left. These messages rotate every 5
seconds.
Figure 15: Message panel
There are two rows of 11-character segments on the left where
message text will be displayed, and there are two rows of number
displays on the right. If there are multiple messages, they will change
every 5 seconds, or you can push the UP or DOWN buttons to force a
23
change to another message at any time. When alarm conditions are
active, corresponding messages will display here.
Some of the segments can display different variations. For example,
you can display RAIN, RAIN RATE, RAIN EVENT, DAY TOTAL,
WEEK TOTAL, MONTH TOTAL, YEAR TOTAL, and TOTAL. After
such a segment has been selected with the LEFT/RIGHT keys, you
can select between these variations by pressing the SET key
(repeatedly as necessary).
Now we discuss the various information segments in the display while
in normal mode.
7.1.1 TIME Segment
Figure 16: Time and Date segment
This segment (Figure 16) displays the current time and date. When
connected to Wi-Fi, the time will be synchronized with a NIST atomic
clock once a day, otherwise you must set (or correct) it manually using
console functions. The time will be displayed in Universal Coordinated
Time until you set the correct time zone offset using the console
functions.
When the arrow indicator is in this segment the following messages
will appear in the message panel:
1. Current year, and day of the week
2. Time of alarm and status of alarm (on/off)
3. Current moon phase (see “Other Console Functions” on page 44
for detail)

7.1.2 LIGHT Segment
Figure 17: Light and UV-index segment
This segment (Figure 17) displays the current solar radiation (light)
and ultra-violet index (UV-index). The light is the overall intensity of
sunlight and its theoretical maximum varies with location and time of
year. The actual value also depends on atmospheric conditions
(clouds, vapor, etc.) and varies throughout the day. The UV-index is a
value that gives an indication of the strength of harmful UV radiation
and can be helpful to know when protection from the sun is advised. A
qualitative indication of the strength of UV radiation is also included
(LOW etc.)
When the arrow indicator is in this segment the following messages
will appear in the message panel, each with a corresponding time
stamp:

7.1.4 OUTDOOR Segment
Figure 19: Outdoor conditions segment
This segment (Figure 19) displays the current outdoor temperature
and humidity, as measured at the location of the outdoor sensor
package. When the arrow indicator is in this segment, the messages
that appear on the message board are the same as for the indoor
conditions, except they reflect outdoor conditions.
7.1.5 PRESSURE Segment
Figure 20: Barometric pressure segment
This segment (Figure 20) displays the current barometric pressure, a
historical graph of pressures, and a pictorial weather forecast.
26
Pressure is measured at the location of the console, but of course
reflects both indoor and outdoor pressure as these are identical.
The pressure indicated may be absolute (ABS) or relative (REL),
depending on the variation you have selected using the SET key. The
absolute pressure is the pressure measured at your console’s location
(altitude). Relative pressure refers to the pressure measured by your
console (absolute), corrected to the value that would exist if your
station was located at sea level. The relative pressure is what is
normally published by official weather stations.
Below the pressure values there is a historical graph. This graph can
be configured to display 12 or 24 hours of history and will give you
some insight into how pressure has been changing. Falling pressures
typically indicate worsening weather (to come), and rising pressures
indicate good/better weather is to come. Rapid rise or fall indicates the
passage of a “front.”
Below the graph you will see a pictorial forecast for the next 12 hours.

7.1.6 WIND Segment
Figure 21: Wind speed and direction segment
This segment (Figure 21) displays wind related information. Inside the
circular “compass rose” you will find two arrows (if they overlap only
one will be visible). The “thicker” arrow indicates the most recently
measured wind direction 16 seconds or less ago). The “thinner” arrow
represents the average wind direction in the prior interval of 16
seconds. This allows insight into the change of direction of the wind.
Both arrows can take 16 specific values: N, NNE, NE, ENE, E, ESE,
SE, SSE, S, SSW, SW, WSW, W, WNW, NW, and NNW. Therefore,
these indications are only accurate within 22.5 degrees.
When the arrow indicator is in this segment you can use the “SET”
button to show variations. The variation shown above displays last
measured wind speed in the center of the compass rose. The other
variations display “wind gust” speed, or wind direction in degrees (thus
allowing more precision than just the arrows).
When the arrow indicator is in this segment the following messages
will appear in the message panel, each with a corresponding time
stamp:

7.1.7 FEELS LIKE Segment
Figure 22: Dew point, wind chill, heat index segment
This segment (Figure 22) displays calculated values related to
temperature and pressure. The values that can be displayed are “wind
chill”, “heat index”, and “dew point.”
Wind chill and heat index are perceptual values that indicate the air
temperature as experienced by humans, as opposed to the measured
ambient air temperature. The passing flow of lower temperature air
makes it feel “colder” and this is reflected in the wind chill temperature.
Conversely, if it feels warmer than the measured air temperature due
to the effects of humidity, we use a heat-index temperature to indicate
how warm it feels.
The “dew point” is not a perceptual value, but it is calculated from the
sensor values (temperature and humidity). The dew point is the
temperature to which air has to be cooled to become saturated, and
beyond which airborne water vapor would become liquid (dew).

7.1.8 RAIN Segment
Figure 23: Rain segment
This segment (Figure 23) displays rainfall related values. The values
that can be displayed (use the “SET” button when the arrow is in the
segment) are: RAIN RATE (amount of rain accumulated in past 60
minutes), RAIN EVENT, RAIN TODAY, RAIN THIS WEEK, RAIN THIS
MONTH, RAIN THIS YEAR or TOTAL RAIN. “RAIN EVENT” means a
single period of rainfall not interrupted by a rain rate of 0. Thus, if it
rains for 10 minutes, RAIN EVENT will display values for that
10-minute period. Likewise, if it rains continuously for 4.5 hours, the
values will pertain to the whole 4.5-hour period.
When the arrow indicator is in this segment the following messages

TRANSMITTER ID
Once you have selected the desired category, you can change modes
to where you can actually see and modify the related settings for the
category by pressing the RIGHT key. For each setting displayed you
can change the value or choices by using the UP/DOWN keys,
repeatedly if necessary. Holding these keys down for two seconds or
more will cause rapid increase or decrease of the selected value.
Continue with the RIGHT key to move on to other settings within the
category or leave settings mode and return to normal mode by
pressing the HISTORY key, or simply waiting 30 seconds or more
without pressing any button.
7.2.1 TIME SETTING
The following sub-settings are available in the “TIME SETTING”
category:
1.
2.
3.
4.
5.
TIME FORMAT: A choice between 12H or 24H time display is
available
DATE FORMAT: The following date format choices are available:
MM-DD-YYYY, DD-MM-YYYY, or YYYY-MM-DD
TIME: Use this to manually set the current time and date. Use up
or down buttons to change the blinking digits, use the RIGHT key
to advance from hours to minutes, to month, to day, to year.
TIME ZONE: Here you can set the time zone offset for your time
zone. Offset 0 would be UTC or GMT, offset -8, for example,
corresponds to Pacific time, etc.
DAYLIGHT SAVING TIME: Switch on to have the time
automatically correct for Daylight Saving Time.
31
6.
NORTH/SOUTH: Set which hemisphere you are located in so that
moon phases can be displayed correctly.
7.2.2 UNIT SETTING

category:
1.
2.
3.
4.
5.
LIGHT UNIT: A choice of lux, fc, or w/m2
TEMPERATE UNIT: A choice of Celsius (C) or Fahrenheit (F)
BAROMETRIC UNIT: A choice of hectopascal (hPa), inches
mercury (inHg), or millimeters mercury (mmHg)
WIND SPEED UNIT: A choice of km/h, mph, knots, m/s, or
Beaufort (bft)
RAINFALL UNIT: A choice of mm, or inch
7.2.3 RECORD SAVE INTERVAL
This category has only one setting and it affects the interval (in
minutes) after which sensor data is recorded. If set to “5 minutes” for
example, the current settings are recorded to permanent storage
every 5 minutes. Use the RIGHT key to activate the setting and then
UP/DOWN to change the interval as desired.
7.2.4 RAIN SEASON SETTING
For official recording of weather results, rain is often tracked over a
12-month period that does not start on January 1. Using this category’s
only setting you can choose the month whose first day is the official
start of the statistical rainfall season. Use the RIGHT key to activate
the setting and then UP/DOWN to choose the desired month.
If you chose OCT, for example, annual rain totals, maximum and
minimum will reset to 0 on October 1 each year. Which month to use
depends on your location’s official definition of the rain season.
Consult online sources to find this information.
32
7.2.5 BAROMETRIC SETTING
This category offers only one setting, called BAROMETRIC HISTORY.
It allows you to choose between a 12 hr. or 24 hr. historical interval for
graphing past barometric pressure information. Use the UP/DOWN
buttons to select as desired. The graph will display a 12 hr. or 24 hr.
scale above or below the graphing area.
7.2.6 KEY BEEP SETTING
This category offers one setting to have keys beep, or not, when
pressed. Use the UP/DOWN buttons to select as desired.
7.2.7 CALIBRATION SETTING
This category offers settings through which you can alter values
obtained from the sensors before display or recording. This
functionality is generally used to make sure that the displayed and
recorded values match those of a reference measurement or
instrument. The most often used example of this concerns absolute
and relative pressure measurements. More on that in a moment.
There are also a few sub-settings that are not true settings, but rather
total values. These relate to rainfall totals an can be set to desired
starting values. This may be useful when installing the weather station
in the middle of a rainfall season. Totals can be set (from the initial
value of 0) to known values for the current year, month etc. so that,
going forward the console will display correct values (as if you had the
weather station all along).
All calibration settings generally offer an OFFSET, or FACTOR
(COEFFICIENT). A recorded and displayed value is computed from
the sensor value by multiplying the sensor value by the FACTOR and
then adding the OFFSET. Where factors are not offered as a setting,
the factor will be 1. This will also be the default factor. The default
offset will be 0. Frequently only barometric settings will need
adjustment!
33
While changing a setting, the console displays what the current sensor
value is with this offset or factor applied so you can either determine
desired offset beforehand, know what you reference value is and
manipulate offset until the reference value is matched. Offset values
should be specified in the selected units for that sensor!
This category offers the following sub-settings to change:
1.
2.
3.
4.
5.
6.
7.
IN TEMP OFFSET: The value you select will be added to the
indoor temperature sensor value before display and recording.
IN HUMI OFFSET: The value you select will be added to the
indoor humidity sensor value before display and recording. When
using a value other than 0 is it possible to compute humidity
values below 0% or above 100%. Such values will be “clipped” to
0%, respectively 100% if that is the case.
OUT TEMP OFFSET: Similar to IN TEMP OFFSET, but for
outdoor temperature sensor.
OUT HUMI OFFSET: Similar to IN HUMI OFFSET, but for outdoor
humidity sensor.
ABS PRESS OFFSET: The value you select will be added to the
absolute barometric pressure reading (actual sensor value). See
note below.
REL PRESS OFFSET: The value you select will be added to the
calibrated absolute barometric pressure reading (sensor value
plus ABS PRESS OFFSET). See note below.
WIND DIR OFFSET: The value you select (in degrees) will be
added to the wind direction sensor value. If resulting values
exceed 359, 360 will first be subtracted (so that 370 becomes 10),
and if values less than 0 would result, 360 is first added. This
setting is useful if, after permanent installation your reference
indicates that your wind direction is systematically different from
the reference and can be used to prevent having to re-orientate
the outdoor sensor package. IMPORTANT: If you are installing in
the southern hemisphere and followed earlier directions, you must
34
8.

13.
use an initial offset of 180 here and subsequently adjust for small
differences relative to a reference.
WIND SPEED FACTOR: The value you select will be multiplied
with the sensor value. If your wind speed consistently differs from
a known good reference (these are very hard to obtain), by a
constant factor, you can make an adjustment here. The allowable
range is 0.1 minimum to 2.5 maximum in 0.1 increments.
RAINFALL FACTOR: The value you enter here is multiplied with
the rain rate sensor value. If your rain rate consistently differs from
a known good reference (these are very hard to obtain), by a
constant factor, you can make an adjustment here. The allowable
range is 0.1 minimum to 2.5 maximum in 0.1 increments.
RAIN DAY TOTAL: The value you enter here is not an offset or a
factor, but rather represents the total amount of rain seen so far for
the current day. It should rarely need an adjustment after initial
installation and setting. Allowable values are 0 – 9,999 mm or
equivalent in other units.
RAIN WEEK TOTAL: The value you enter here is not an offset or a
factor, but rather represents the total amount of rain seen so far for
the current week (remember the week starts with Sunday). It
should rarely need an adjustment after initial installation and
setting. Allowable values are 0 – 9,999 mm or equivalent in other
units.
RAIN MONTH TOTAL: The value you enter here is not an offset or
a factor, but rather represents the total amount of rain seen so far
for the current month. It should rarely need an adjustment after
initial installation and setting. Allowable values are 0 – 9,999 mm
or equivalents in other units.
RAIN YEAR TOTAL: The value you enter here is not an offset or a
factor, but rather represents the total amount of rain seen so far for
the current statistical rain year (may not start in January, see
section 7.2.4 on page 32). It should rarely need an adjustment
35
after initial installation and setting. Allowable values are 0 – 9,999
mm or equivalents in other units.
14. RAIN TOTAL: The value you enter here is not an offset or a factor,
but rather represents the total amount of rain seen since the last
reset of the unit or since this value was last changed. It should
rarely need an adjustment after initial installation and setting.
Allowable values are 0 – 9,999 mm or equivalents in other units.
15. TRANSMITTER ID: This is not a setting you can change. Rather it
tells you a number that identifies the type of outdoor sensor from
which sensor data was received. This is mostly useful for
troubleshooting scenarios.
Note: Before making adjustments to WIND SPEED FACTOR or
RAINFALL FACTOR please make sure your outdoor sensor
package is mounted level and that the wind vane can move
unobstructed and that there is no “slippage” on the axis (make
sure set-screw is tight).
7.2.7.1 Calibration of barometric pressure settings.
Unlike all other calibration settings where factory installation ensures
that, within the specified instrument precision, factors of 1.0 and
offsets of 0 are appropriate and correct, this generally cannot be done
for relative barometric pressure readings. To understand consider the
following.
Absolute barometric pressure, can be calibrated at manufacturing time
by comparing with a precise instrument that measures pressure at the
same location. In practice, sometimes small adjustments of a few hPa
may be needed. The relative pressure represents what the air
pressure would indicate if your station was at sea level and depends
on the altitude of your console and cannot be known in advance. This
is why it needs an offset adjustment.
There are different manners in which to handle this adjustment. We will
outline a reliable procedure below, which requires adjusting both
36
pressure offsets. The method assumes that you have an official airport
sufficiently nearby to act as a reliable reference. Usually distances of
up to 25 miles work reliably, but this is not always true and depends on
geography. We start by assuming that your station’s absolute pressure
reading is correct and needs no offset correction.
1.
2.
3.
4.
For this procedure we will get the most precise results if our
display for pressure is in hPa units. Even if you do not want to use
those units eventually, set the console to use them for now.
Determine the altitude, or elevation above sea level, of your
station’s console. This measurement is necessary to account for
the difference in air pressure caused by the elevation of your
console. Elevation above sea level reduces the absolute pressure
measured by your sensor. Determine this altitude using a GPS, or
look it up using a tool such as this web site:
https://www.freemaptools.com/elevation-finder.htm. You can
input your location’s GPS coordinates, or manipulate the map to
your location. Click on “Estimate Elevation” and observe the result.
For an example we will use a console location at 42 ft. above sea
level.
This tool will provide the ground level elevation at your location, so
you will need to add the right amount for how high above ground
level your console is. If you are on a ground floor and have the
console on a desk, you’ll have to add something like 3-4 ft. If you
are using a GPS system that tells you elevation, make sure it is
right next to the console and you’ll be able to read the correct
elevation right from the GPS results without further adjustment.
With the correct altitude/elevation in hand you will need to
determine the correct offset. To be added to the absolute pressure
reading in order to compute relative pressure (sea level
equivalent). Correction tables can be found on-line in many places.
One example is the table found at the web site at
https://novalynx.com/manuals/bp-elevation-correction-tables.pdf.
Locate your elevation in the first column and read the correction in
37
the third column. This table, however is rather coarse, making it
hard to be precise. An alternative is an on-line calculator such as
the one found here:
http://www.csgnetwork.com/barcorrecthcalc.html
For our example of 42 ft. above sea level we input 42 ft. of
elevation and a standard pressure of 1013.25 hPa/mb and press
calculate. We find an “absolute barometer value” that should be
-1.5626061222588443 hPa lower than at sea level. The inverse
(because relative pressure is higher than absolute pressure) of
this number will be our “REL PRESS OFFSET” value. Use the
settings procedure to input +1.6 (nearest rounded value we can
input). Remember we assume “ABS PRESS OFFSET” to be 0, so
check and change that as well if necessary.
5. Now we need a reliable reference for pressure at sea level. Locate
the official identifier for the nearest airport. Refer to “World Airport
Codes” at https://www.world-airport-codes.com or a similar
reference. Enter your location or nearby airport name, and press
“Search.” Select the correct airport from your search results and
click on it. For example, search for “Mountain View” and click on
“Moffet Field.”
6. From the resulting page find the ICAO code, if listed. Otherwise
use the IATA code. For the example above, you would find IATA
code “NUQ.”
7. Now go to a web site like AVIATION WEATHER CENTER (for US
locations) at https://www.aviationweather.gov/metar?gis=off and
enter the code you found in step 2, and click “Decoded” (to make
the next step easier) before requesting the METAR information.
For the example we would enter “KNUQ” and find a result output
like: “30.09 inches Hg (1019.0 mb) [Sea level pressure:
1019.1 mb]”
8. Make sure your console is displaying REL barometric pressure
and compare its value with the value from the airport. In our
example, the REL display was 1022.9 where we expected 1019.1.
38
This then tells us that our displayed REL pressure is 1022.9 –
1019.1 = 3.8 hPa different from the reference source.
9. Since we assumed the absolute pressure measured was correct,
and we presumably calculated the elevation related offset
correctly, we must conclude that the absolute pressure was not
correct after all. It appears to be 3.8 too high, so we’ll now enter an
offset of -3.8 in the settings for ABS PRESS OFFSET.
10. For a more precise procedure, locate a very precise barometer
that you can place right next to the console, you would adjust
“ABS PRESS OFFSET” until the ABS pressure reads identical.
You would then still apply the calculated “REL PRESS OFFSET”
as above, and then, as a final step, further adjust “REL PRESS
OFFSET” until it displays the reference value from the airport. This
procedure would also produce the correct relative pressure, but
due to a precise calibration of the absolute pressure, it too is
correct.
The first procedure above generally works quite well, but for stations at
fairly high altitudes (e.g. 5,000 ft. or higher) it may be more incorrect
than at lower altitudes. In such cases comparisons with other known
correct, and nearby at similar altitude, stations may help.
Now that calibration is complete, feel free to change the pressure units
to whatever you like.
Note: Airport METAR data is often only updated every 10, 15 or even
30 minutes. If you use the information in the procedure above,
you may be looking at pressure data that is out of date by as
much as the update interval. To get best results observe
several times and figure out the update interval and then use
two values for the procedure: one taken immediately after an
update, another taken about halfway through the interval.
Note: It is also a good idea to observe some more after the calibration
procedure is complete to make sure the numbers are correct.

7.2.8 Alarm Mode
In ALARM mode you can activate alarms that will alert you to the
presence of alarmingly high or low sensor values. From normal mode,
you can enter alarm mode by pressing the ALARM key. By pressing
the ALARM key once you will enter “high” alarm mode where you can
set or change alarm conditions for alarmingly high sensor values.
Pressing ALARM again will activate “low” alarm mode, for alarmingly
low values. High alarm mode also includes a conventional time-based
alarm (alarm clock).
When an alarm condition is met, the alarm will sound a loud beep, and
) will flash. The message panel will display a
the alarm icon (
message appropriate for the alarm condition. Press any button to
silence the alarm beep. The flashing alarm icon will stay until the alarm
condition itself is no longer satisfied (e.g. temperature drops below
alarm value, etc.)
Once in alarm mode use the LEFT/RIGHT keys to witch between the
various possible alarms and use the UP/DOWN keys to change the
value setting for a particular alarm. The SET button is used to switch a
particular alarm from enabled (ON) to disabled (OFF). To leave alarm
mode, press the HISTORY button or it will happen after 30 seconds of
inactivity.

buttons to switch among
Within each category you can use the
max/min records of the various weather values. Each minimum or
maximum will be displayed in its respective display segment, while a
message in the message panel will indicate what kind of minimum or
maximum is currently selected.
A currently displayed minimum or maximum value can be cleared from
the historical record by holding down the SET button for two seconds.
Return to normal mode by pressing the HISTORY button or it will
happen after 30 seconds of inactivity.
42
7.2.10 History Mode
History mode allows you to inspect the historical records of all
available weather values. The console stores up to 3,552 records,
where each record contains a complete set of weather values at a
particular point in time, along with a time stamp. The recordings are
made at a fixed interval that can be set through settings (see section
7.2.3). At the standard 5-minute interval that means 296 hours, or a
little over 12 days. Once the recording storage is full, the oldest
recording will be overwritten by a newer one, thus always keeping the
3,552 newest ones.
Enter history mode from normal mode by pressing the HISTORY
button. The message panel will then show either “HISTORY NONE
RECORD” if no records are stored, or it will display a message like
“HISTORY P/R 1.07” and “YEAR 2018”.
History records are kept in “pages” of 32 records each. The “P/R”
number in the message indicates the current page and record number:
in the example above page 1 record number 7. The values themselves
are displayed in their respective display segments. You can cycle
through record numbers using the UP/DOWN keys, and through
pages using the LEFT/RIGHT keys.
When in history mode it is also possible to clear all historical records.
Do this by holding down the SET button for 2 seconds.

8.2 Moon Phases
The phase of the moon for the current day (night) are displayed as an
icon in the segment that displays moon phase, RF signal strength, and
storage utilization. If the “arrow” is in this segment, the message panel
will also describe the moon phase in words. The table below shows the
possible icons and their descriptions. Note that icons mimic the actual
appearance of the moon and therefore are different for installations in
the northern hemisphere vs. southern hemisphere.

8.3 RF Reception strength
The strength of RF signal reception from the outdoor sensor package
can be checked by looking at the vertical bar(s) to the right of the
antenna symbol. This symbol is found in the same segment as the
moon phases. The strongest signal is indicated by three bars of
increasing length. Less signal quality may show 2, 1 or no bars. This
may be helpful when you seem to have reception problems.
8.4 Recording storage capacity used
The console can store historical sensor data on internal storage. The
storage is permanent and will not be lost if there is a power outage.
There is room for 3,552 records and you can see how much of this
45
storage is used by inspecting the “storage capacity used” indicator.
This is found in the same segment as the moon phases and RF signal
strength indicator and is depicted as a circle with marks at 0%, 25%,
50%, 75% (100% is when the circle is full). Once the full capacity is
used new data will replace the oldest stored data (the circle will remain
full).
8.5 Beaufort Wind Force Scale
If you have selected the use of Beaufort wind speed units, you can
use the table below for reference. The Beaufort scale is based on
qualitative wind conditions and how they would affect a ship’s (frigate)
sails (so yes, it is an “old” standard). It is therefore less precise than
the other scales but is still in use in various locales.
Wind speed

9.1 Connecting the Weather Station Console to Wi-Fi
To send weather data to these services you must connect your
console to the internet via Wi-Fi. The console can only operate using
Wi-Fi when the external power adapter is connected and plugged in!
Note: If you are testing the setup with the outdoor sensor package
nearby and indoor, you may want to consider connecting to
Wi-Fi, but not yet configuring any of the weather services. The
reason is that while indoor the temperatures and humidity
recorded by the outdoor sensor, and as reported to the weather
service(s) will reflect indoor conditions, and not outdoor
conditions. Therefore, they will be incorrect. Furthermore, the
rainfall bucket may be tripped during handling, causing rain to
register while it may not actually have been raining. One way to
prevent this is to follow all instructions, except to use an
incorrect password, on purpose! Then, after final outdoor
installation, come back and change the password after clearing
console history. That will start uploading to the services with a
clean slate.
9.1.1 Download mobile application
Wi-Fi configuration is done using your mobile device, either iOS or
Android. Start by downloading the “WS View” application from the
Apple App Store or Google Play store, as appropriate for your device.
9.1.2 Put console in Wi-Fi setup mode
Plug in the external power adapter and connect to the console if you
have not already done so. Next, see Figure 24 and press and hold the
DOWN and ALARM buttons (1) simultaneously for five seconds. The
(2)) in the time segment of the display will start flashing
Wi-Fi icon (
and the message panel will say: “WI-FI STATUS MODE -- B”. The
console will now have activated a Wi-Fi network named starting with
“EasyWeather Wi-Fi” and you will connect to it with your mobile device.
48
Figure 24: Activating Wi-Fi setup mode
9.1.3 Connect mobile device to EasyWeather Wi-Fi
Using your phone’s Wi-Fi setup capabilities (WLAN setup for Android,
Wi-Fi for iOS devices), connect your phone to the EasyWeather
network now advertised by the console.
For Android users:
49
Answer “NO” to the “No Internet access” message!
For iOS users:
Look for the network named “EasyWeather-WIFI” followed by four
characters. Tap on it to connect to that network. You will see a warning
“Unsecured Network” under the name of the “EasyWeather-WIFI”
network. This is normal and can be ignored.
9.1.4 Register a Personal Weather Station (PWS) with
wunderground.com
If you are planning to use wunderground.com you must have an
account and register a (new) personal weather station. You may do so
50
on the wunderground.com web site, or you can do this from within the
mobile app. Take note of the PWS identifier (ID) and the password that
will be generated for you.
9.1.5 Activate setup application
Now activate the application you have downloaded on your mobile
device. The following instructions will generally show screen shots for
the Android application side by side with the iOS version, or iOS below
Android when there is not enough space for side by side.
Figure 25: Mobile application – Main screen (Android & iOS)
The main screen will indicate your station is off-line (because it is not
yet connected to Wi-Fi). At this point, if you have not already done so,
you can register on wunderground.com and create your PWS by
pressing on the settings icon and activating the “Register with
wunderground” option. Fill out the form and take note of the station ID
and password.

“Sites” are the means by which WOW organizes weather data the you
contribute. Basically, WOW builds a personal web site for your
weather station. Associated with the web site is two items you will need
to allow uploading of data:
Site ID: This is an arbitrary number that is used to distinguish your site
from another. This number appears (in brackets) next to or underneath
the name of your site on the site information page, for example:
6a571450-df53-e611-9401-0003ff5987fd
Authentication Key: This is a 6-digit number that is used to ensure
data is coming from you and not another user.
Begin setting up a new site by clicking “Enter a Site”:
Figure 40: WOW New Site menu
You will be presented with a form where you detail your station’s
location and a bunch of other settings related to how you wish the site
to operate. After you complete the setup, you should see:

your computer or laptop. The following operating systems are
supported: Windows version XP, Vista, 7, 8 or 10. You may download
the software from: http://www.ecowitt.com/manual/software/
10.1 Installation and configuration
After downloading, install the software by decompressing the archive
named “WeatherSmartIP.” You will then have a file called
“WeatherSmartIP Setup.exe”. Double click it to start installation.
After making sure your PC is on the same network segment as your
console (using Wi-Fi or Ethernet cable), start the WeatherSmartIP
application that is now installed and select the IP address on that
network segment that your computer is using(this window will pop out
when your PC has more than one IP addresses):
Figure 48: PC Software – IP selection
Most computers have only one IP address, but if yours has more than
one and if you don’t know which IP address is the correct one, go to
your control panel and inspect the properties of the Wi-Fi network that
the console is connected to:
71
Figure 49: Determining Wi-Fi network addresses
Now, choose “Select Device” from the System menu and select the IP
address that your console is using (you can find this information in the
mobile application’s “Device List”). If you only have one weather
station you should only be offered one choice.

11 Maintenance
The following steps should be taken for proper maintenance of your
station
1.
Clean the rain gauge once every 3 months. Rotate the funnel
counter-clockwise and lift to expose the rain gauge mechanism,
and clean with a damp cloth. Remove any dirt, debris and insects.
If bug infestation is an issue, spray the array lightly with
insecticide.
Figure 60: Rain gauge maintenance
79

3.
4.
5.
Clean the solar radiation sensor and solar panel every 3 months
with a non-abrasive slightly damp cloth.
Replace batteries every 1-2 years. If left in too long, the batteries
may leak due to environmental challenges. In harsh environments,
inspect the batteries every 3 months (while cleaning the solar
panel).
When replacing the batteries, apply a corrosion preventing
compound on the battery terminals, available at Amazon and most
hardware stores.
In snowy environments, spray the top of the weather station with
anti-icing silicon spray to prevent snow build up.

12 Troubleshooting Guide
Look through the following table and locate an issue or problem you
are experiencing in the left column and read possible solutions in the
right column.
Problem
Outdoor
sensor not
reporting to
console
Dashes (--)
on the
display
console
Solution
Check that the outdoor transmission LED on the
bottom is flashing approximately every 16 seconds.
See Figure 2 item 9.
If the batteries were recently (re)placed, check correct
polarity was used and/or reseat the batteries. If the
batteries are old, replace them.
If the LED is now flashing every 16 seconds, proceed
to the next step. If it is not flashing and you have
repeated battery checks and placement, you may
have a defective unit.
Make sure you have fresh batteries in the display
console.
If the batteries may have been changed in the remote
and/or the console, and the console has not been
reset, the solution may be as simple as powering
cycling the console: remove both batteries and
external adapter for about 10 seconds and reconnect.
If you still have problems, bring the outdoor sensor to
a location about 10 ft. away from the console for
testing. Power cycle the console as described above.
Do not touch any buttons for several minutes to allow
the console to “discover” the outdoor sensor. During
this process the remote sensor search icon
will
flash on the display. Wait several minutes for this icon
to turn off.
If the search icon turns off and the outdoor
temperature and humidity are still showing dashes
(--), the remote sensor is defective. If the sensor
properly syncs up, proceed to the next step
“Intermittent problems with outdoor sensor reception
on console.”

Solution
There may be a temporary loss of communication due
to signal quality issues caused by electrical
interference or other location related factors
(obstacles along line of sight).
To troubleshoot, install a fresh set of batteries in the
remote sensor array and console. For cold weather
environments, install lithium batteries.
If problems remain with fresh batteries, ensure power
adapter is not too close to the console, and the
console is not close to other electrical noise
generating devices such as TVs, monitors, computers
and transmitting devices.
If you still have intermittent problems move sensor
and console closer together, but not closer than 5 ft.
Also check that there are no metal barriers like
aluminum siding, or metal wall framing, along the line
of sight between sensor and console. Relocate sensor
and console as necessary to avoid obstacles.
Depending on natural barriers you may also have to
move the outdoor sensor higher and/or closer.
During installation testing it is useful to test with both
console and outdoor unit in the same room. Allow up
to one hour for the sensors to stabilize and adjust to
room temperature. The indoor and outdoor
temperature sensors should agree within 4 °F (the
sensor accuracy is ± 2 °F).
If these values still disagree, use calibration offsets for
one or both sensors (see section 7.2.7) to adjust to a
known good reference temperature.
The procedure here is that same as for outdoor/indoor
temperature. The sensors should agree within 10 %
(the sensor accuracy is ± 5 %)
If these values still disagree, use calibration offsets for
one or both sensors (see section 7.2.7) to adjust to a
known good reference humidity.
Relative pressure refers to sea-level equivalent
temperature and should generally agree closely with
the official station. If there is a disagreement, make
sure you are not looking at absolute pressure, in
particular if your station is not near sea level. Also
check at different times due to occasional delays in
updates to the official station.

Solution
Redo the pressure calibration procedure described in
section 7.2.7.1.
The barometer is only accurate to ± 0.09 inHg (3 hPa)
within the following relative pressure range: 20.67 to
32.50 inHg (700 – 1,100 hPa), which corresponds to
an altitude of 9,000 ft. (2,750 m) down to 2,500 ft. (750
m) below sea level. At higher altitudes, you should
expect a possible lesser accuracy and non-linearity
effects in the error (the calibration offset only allows
for a partially linear correction).
Make sure your time zone and daylight savings time
setting is correct (even when connected to the Internet
via Wi-Fi this is needed). If not connected to the
Internet via Wi-Fi, you may also have to manually set
the correct time.
The weather station console must run for several days
to trend barometric pressure properly and start
producing reasonable forecasts.
The weather forecast is an estimation or
generalization of weather changes in the next 24 to 48
hours and varies from location to location. The
pressure trend is a simplified tool for projecting
weather conditions and is never to be relied upon as
an accurate method to predict the weather.
Check your calendar date and make sure it is correct.
Replace console batteries with a fresh set of batteries
and/or make sure external power adapter is
connected and functioning.
Confirm your station ID is correct. The station ID is all
caps, and the most common issue is substituting a
capital letter O for a 0 (zero) or vice versa. Please note
the digit 0 can only occur in the last part of the station
ID (which is a station number in a city). Example,
KAZPHOEN11, not KAZPH0EN11
Confirm that your password (also called: key) is
correct. It is the password wunderground.com
generated for your station ID. You can also verify it by
logging in to wunderground.com and looking it up
under “My PWS.”
Make sure the date, time and time zone is correct on

Check your router firewall settings. The console sends
data via port 80. If you can access other web sites
using “http” (not to be confused with “https”) this
setting will be OK.
Check for Wi-Fi symbol on the display. If wireless
connectivity is operational, the Wi-Fi icon
will be
displayed in the time segment on the console.
If the symbol is not displayed, but you do remember
configuring it successfully before, check that the
console external power adapter is plugged in and
functional. Wi-Fi use demand more energy than
batteries alone can provide.
If you have never been able to configure Wi-Fi to a
working state, make sure your Wi-Fi supports 2.4 GHz
signals (801 type B or G, or N). The console does not
support Wi-Fi that uses the 5 GHz spectrum.
Make sure you configured the correct SSID and
password. Repeat the procedure if necessary to
verify.
The console does not support so-called “captive
Wi-Fi” networks. These are typically “guest” type
networks where users have to agree to terms and
conditions before being connected.

DESCRIPTION
Absolute air pressure is the air pressure
registered on a barometer without
regard to altitude.
A barometer is a device that measures
the pressure of the air pushing on
it—this measurement is called the
barometric pressure. We don’t actually
feel the barometric pressure because
the air pressure is pushing equally in
every direction.
An indicator of wind force strength (not
speed) as it would act on a ship’s sails.
Still commonly in used in some locales
to indicate wind force.
The temperature to which air must be
cooled to become saturated with water
vapor. When further cooled, the
airborne water vapor will condense to
form liquid water (dew), or frost if below
freezing.
The heat index (HI) or humiture is an
index that combines air temperature
and relative humidity, in shaded areas,
as an attempt to determine the
human-perceived
equivalent
temperature, as how hot it would feel if
the humidity were some other value in
the shade.
This is an international standard (SI
system) for measuring air pressure. It
used to be referred to as milli-bar (mb)
and sometimes still is. They are
equivalent.
An instrument that measure relative
humidity of the air. This is expressed as

This is the common unit of
measurement for air pressure in the
United States. It refers to the length of a
standard column of mercury (a liquid
metal) that can be pushed up by the
ambient
air
pressure.
Standard
pressure is approximately 29.92 inHg
One knot is equivalent to one nautical
mile and is sometimes used to indicate
wind speed.
An acronym for “Liquid Crystal Display.”
This is a common type of display screen

The unit of illuminance (a measure of
the intensity of illumination on a surface)
as used in the SI system.

This is similar to inches of mercury,
except expressed in millimeters.
Standard pressure is approximately 760

WIND CHILL
DESCRIPTION
sunburn-producing ultraviolet (UV)
radiation at a particular place and time.
The purpose of the UV Index is to help
people effectively protect themselves
from UV radiation. The UV Index is a
linear scale, with higher values
representing a greater risk of sunburn
(which is correlated with other health
risks) due to UV exposure. An index of 0
corresponds to zero UV radiation, as is
essentially the case at night. An index of
10 corresponds roughly to midday
summer sunlight with a clear sky when
the UV Index was originally designed,
but values above 10 are sometimes
possible. Levels above 8 are
considered “very high” and above 11
are considered “extreme.”
Wind chill (popularly wind chill factor) is
the lowering of body temperature due to
the passing-flow of lower-temperature
air. In other words, the air “feels” colder
than it is because of the chilling effect of
the wind on the skin.

The primary power source for the outdoor sensor is the solar panel.
When available solar power (light over recent period) is insufficient, the
batteries will be used. In outdoor climates that frequently have
sustained temperatures below 0°C (or 32°F) the use of Lithium
batteries is strongly suggested as these are performing better than
Alkaline batteries under such circumstances.
