2. Setup
2.1 Minimum Materials
You will need:
• A Wyze Temp® Plus Programmer
• Two USB A/B male cables
• A Wyze Temp® Plus Probe
• A Wyze Temp® Base
• A Wyze Temp Base power cord
• A magnet
• A Windows 7 or newer computer with the “Wyze-Temp Plus” application.
2.2 Launch the Application
Connect the Wyze Temp Base and the Wyze Temp Plus Programmer to the PC using the A/B
male USB cables. Plug the Wyze Temp Base into a wall outlet using the 24V power cord. Launch the
“Wyze-Temp Plus” application from its location in Windows Explorer. The window that opens will
look like the window seen in Illustration 1.
Illustration 1: The Wyze Temp® Plus application default screen.

3. The Settings Window
Click on the “Settings” button on the lower right hand corner of the plot screen. A new window
should open. This window can be seen in Illustration 2.
3.1 Initializing USB communications
The appropriate COM port should be chosen to communicate with the Wyze Temp Base. If
multiple options are available, open the windows device manager from the control panel, expand the
“Ports (COM & LPT)” section, and unplug the Wyze Temp Base. The COM number that is removed
from the list after this is the COM port the base is using. Reinsert the USB and select the appropriate
COM port in the Wyze Temp Plus application.
Illustration 2: The Settings window.

3.2 Choosing Probe Serial Numbers
In the settings window, six fields exist each for weight and temperature probe, and one graph
tile can plot weight and temperature simultaneously, or can be set up to plot only weight or
temperature. This can be done by setting the probe serial number in the field associated with the plot.
Entering an unused serial number (typically 00000) will allow the tile to ignore the associated value.
For example, a possible use case involving one weight probe (serial number 10) and one
temperature probe (serial number 5550) can be set up to look like one of the options seen in Illustration
3. Note the serial number settings located below each of the plots.
Illustration 3: The top screen capture demonstrates the individual plot settings, the bottom screen
shows the shared plot setting.
Copyright Matrix Product Development, Inc 2014
Each plot can track one weight probe and one temperature probe, allowing up to 12 paired
probes, or six stand-alone probes, or a combination to report to the application.
An option to change the units on the plots exists in the lower right corner of the settings
window, checking the box will enable English units.

4. Using the NFC Wyze Temp® Plus Programmer
Clicking on the “Wand” button on the settings window will open another new window. This
wand application allows a user to field program a probe, extending the utility of a Wyze Temp Plus
probe by granting the user the option to change serial numbers, recalibrate a probe, and change the
averaging period used by the probe.
4.1 Programmer-Probe Interface
The programmer and probe utilize near field communications (NFC) to exchange data. This
wireless method of communication means that the probe housing does not need to be opened, and that
the programmer can be used by simply holding the target etching on the tapered end of the programmer
to the probe compartment with the Matrix Logo. If an error message is received during a programming
attempt, try repositioning the target on the probe. An example of how the programmer should be held
can be seen in Illustration 4.
Programming is accomplished by retrieving the current settings with the “Get Info” button
changing any desired settings, then pressing the “Write Info” button. After the settings are successfully
written to the probe, waking the probe from a sleep state will cause the changes to be implemented.

4.4 Calibration
All Wyze Temp Plus products are shipped pre-calibrated, and can be used directly out of the box.
However, in field calibration can be performed if necessary. The procedure for calibration for probes
with this capability are outlined in this section.
4.4.1 Weight Probe
The probe includes an in field calibration option to increase the accuracy of its readings and can
be accomplished using a single known weight. A step by step example procedure is outlined below:
1. Open the Wand application window and use the “Get Info” button to load in the current probe
settings.
2. Choose a known weight (here 20.77 kg) that can be applied to the Wyze Temp Plus Weight during
calibration. Typically, a weight closer to full scale (22.6 kg, or 50 lb) will yield better calibration
results. Select a wait period in the area circled in Illustration 7, this time period will be the time that is
allotted the user to apply or remove weight in each step. Matrix recommends using at least 40 seconds
for calibration time to ensure accurate calibration results.
3. Write the chosen values to the probe with the “Write Info” button.
Illustration 7: The calibration selection options.
Copyright Matrix Product Development, Inc 2014
4. The probe will need to wake up to start calibration. If the device is already awake, put it to sleep and
wake it again.
5. At this point, an orange LED will start blinking, this means that it is time to remove any weight from
the sensor. During this period, apply the zero weight condition. (Note: if the probe is left laying down,
calibration will not proceed correctly. The device MUST be in the actual use case 0 load condition.)
The orange LED will last the amount of time that was chosen in step 2.
6. When the LED changes to purple, it is time to apply the known weight set in step 2 to the Wyze
Temp Plus Weight sensor. Minimize any motion by the weight during this period to achieve best
results. The purple LED will again last the amount of time chosen in step 2.
7. When the LED returns to its normal green blinking pattern, calibration is completed and the device is
ready for use. It is recommended that prior to use, the probe is tested with a known weight to ensure
calibration was successful.
4.4.2 Temperature Probe
The temperature probe can be successfully calibrated for use over its intended temperature range using
two temperature points (0C and 100C). The method for accomplishing this is outlined in the numbered
steps below. Currently, the wand application does not have temperature calibration options, so the
calibration must be done using the ST M24LRXX_Application_Software.
1. Connect a Wyze Temp Plus Programmer to a USB port on your computer.
1. Start the M24LRXX_Application_Software and select the CR95HF DEMO KIT option at the bottom
of the list in the dropdown box and then click the “Ok” button.
2. On the top of the window click the “Reader Application” option, select the “M24LR64E category,
and select “A” from the menu that expands.
Copyright Matrix Product Development, Inc 2014
3. You should be presented with the screen below:
4. in the area highlighted by the red box, fill both fields with “0011,” this will access the correct
memory location on the Wyze Temp Plus.
5. Click the “Read” button in the blue box. You should see a field appear like the one in the purple box
if this is successful.
6. The first two bytes (FF FF in this example) should be filled in to the field highlighted with orange.
7. The second two bytes (B0 37) are the values we will need to change as outlined in the following
step.
8. The number stored in our field of interest is currently “37 B0” (note: NOT B0 37, this is little endian
format). Using a hexadecimal to binary converter calculator will output the binary value, in this case
we are looking at 0011 0111 1011 0000. We will want to selectively change these values to indicate our
how we want to calibrate as outlined in the next step.
9. There are three areas of this number relevant to temperature calibration, they are as follows:
xxxx xxxx xxxx xxx1 – The bold value, when set to 1, will indicate that we are to calibrate a
point on the next wake up.
xxxx xxxx xxxx 1xxx – The bold value, when set to 1, will indicate that we are calibrating a
100C point. When it is set to 0, we are calibrating the 0 C point.
xxxx xxxx xxxx x11x – The bold value can be equal to 0(00), 1(01), 2(10), or 3(11) and will
Copyright Matrix Product Development, Inc 2014
control how long after wake-up the probe will wait to read the temperature and consider it as
the 0 or 100 point reading. The time waited is 4 minutes at setting 0, with an additional four
minutes for each setting past 0 (01 gives 8 minutes, 10 gives 12, etc.).
10. Selectively change the numbers read out to indicate what you would like to do. For example, if we
want to teach our probe what 100C looks like, give it 4 minutes to come to the correct temperature, and
we have read out the value 37 B0 that we have been using as our example we would make the
following changes:
1111(F) 1111(F) 1111(F) 1111(F) 1011(B) 0000(0) 0011(3) 0111(7) to
1111(F) 1111(F) 1111(F) 1111(F) 1011(B) 1001(9) 0011(3) 0111(7)
11. Enter the new number into the box highlighted in orange, and with the probe on the wand, press
“Write.”
12. The next time the probe wakes up, it will calibrate itself to the indicated point after the chosen
amount of time, then continue normal operation. The probe will indicate it is calibrating by flashing an
orange LED when calibrating the 100C point, or a purple LED when calibrating the 0C point.
13. A complete recalibration will require that both these points are measured. To accomplish this, the
same steps should be followed while indicating the other point type.
4.5 Averaging Period
The Wyze Temp Plus Weight Probe will sample at a fixed rate and keep a running average of
the values it reads since its last report to the base. Once the end of an averaging period is reached it will
transmit the result then start a new average. This averaging period is configurable by the user in 1
second steps between 1 and 30 seconds. Longer averaging periods are more likely to eliminate error
associated with motion applied to the mass and increase battery life by reducing the number of
transmits. For these reasons, longer averaging periods recommended. For more frequent updates, a
smaller averaging period can be chosen as well. The drop-down menu to set the averaging period is
highlighted in illustration 8.

4.6 Retrieving the Current Settings
In many cases, it can be useful to see how the probe is currently configured. This can be
accomplished by applying the programmer to the probe as previously described, and pressing the “Get
Info” button. If successful, this will populate the boxes with the current setting of the probe.
4.7 Other Options
The Advanced (Read Only) settings and fields are not necessary for field utilization of this
device, and are implemented as measures to help Matrix troubleshoot. The pressure check options are
currently in development and should not be changed by the user.

5. Operating the Wyze Temp® Plus Probe
The Wyze Temp Plus Probe is calibrated on delivery and is set up for immediate use. A quick
start guide is included with this guide to start data logging immediately. The following section details
how to use the device in a more in depth manner.
5.1 Turning the Wyze Temp® Plus Probe on and off
The probe utilizes a reed switch that can be closed via a magnet. Holding a magnet to the LED
on the probe will toggle the power. The Wyze Temp Plus probe uses its LED to signal if it is turning off
or waking up. When the device is turning off, it will display a solid blue LED for approximately half a
second. When turning on, the Wyze Temp Plus Probe will display a green LED for approximately one
second. A complete description of LED colors and their meanings can be seen in the next section.

6 Accessing Logged Data
6.1 The Data Log File
The Wyze Temp Plus data acquisition program will in addition to displaying a real-time plot, log the
data to a file in windows. This file can be found in the following default directory:
C:\ProgramData\wyzetempplus\
If windows explorer does not show “ProgramData” as an option, it is because the file is hidden by the
Windows operating system. The logged data can still be accessed by entering the above address into the
address bar of Windows explorer.
The data for the current session will be named by date. For example, data recorded on March
28, 2014 will be named “data_20140328.txt” There will be a similarly named file “com_20140328.txt”
This second file contains raw output from the base and can be ignored. The data stored in the data file
will have the following format:
<date>, <time>, <probe serial number>, <data point>
The comma delimitation will allow for excel processing, and data points from all active probes will be
listed in the order they were received by the Wyze Temp base (i.e. the data will NOT be sorted by probe
number or type).
If a new data logging session is started, and a file was already generated on the current date, the
new data will automatically be appended to the already existing data. If this is not desired, simply
renaming the existing file will cause the program to regenerate the standard file name for the new data.

7 Troubleshooting
This section will outline potential fixes for undesired behaviors.
7.1 Potential Errors
Problem
Fix
The Wyze Temp Plus Weight Probe is transmitting
incorrect weight values.
Calibrate the device, being careful to apply the use
case 0 load during the first LED pattern, and
having a motionless applied weight during the
second LED pattern.
The Wyze Temp Plus Weight Probe is blinking a
white LED, is not transmitting, and cannot be put
to sleep.
The probe has entered a “pressure test” this mode
will be exited after some time (the time span of
the test varies based on user settings) and
operation will return to normal. If a red LED
blinks in place of the green one after this test,
cycle the wake state and the green LED will
return. If the user needs immediate use of the
probe, unplugging the field replaceable battery for
10 seconds, then reapplying it will force the probe
to exit the pressure test. In both cases, the user
must deselect the “Check Pressure Test on
Startup” prior to waking the probe using the Wyze
Temp Plus programmer.
The green LED will occasionally remain on for a
few seconds when it should be blinking.
This is a known firmware bug. The operation of
the device is not negatively impacted and the error
is only cosmetic.
The red LED is blinking
This is a universal indication that an error has
occurred. Usually the red LED is caused by a
weight that is outside its allowable range. If this
occurred after a recent calibration, the calibration
process should be repeated. If this has occurred
during normal operation, make sure that no excess
weight has been or is being applied to the Wyze
Temp Plus Weight Probe. After the weight error
has been resolved, resetting the probe will return
the LED color to green. If the red LED pattern
persists, and erratic operation such as calibration
occurring when not set is noted, the device should
be returned to Matrix for more advanced
troubleshooting.
The Wyze Temp Plus Weight Probe will not go to
sleep after 10 minutes without base contact.
The Wyze Temp Plus Weight Probe is in a data
logging mode. At the current revision, the probe
should not be able to enter this mode because it is
automatically disabled by the Wyze Temp Plus
Programmer. Reprogram the probe using the NFC
application. No settings need to be changed, the
Copyright Matrix Product Development, Inc 2014
Programmer only needs to rewrite the settings
currently on the probe.
The Wyze Temp Plus Weight Probe is turning
itself off within a minute and a half of wake up,
and there is no data being reported on the screen.
The Wyze Temp Plus Weight Probe is not
receiving communications from the Wyze Temp
Base. Make sure that the correct base is being
used, and that the serial number programmed into
the probe is correct. Verify that the base is being
powered via the external two-pin power supply.
