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.
Illustration 2: The Settings window.
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.

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
Illustration
4: An example of Wyze Temp Plus Programmer placement.
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
Illustration 7: The calibration selection options.
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.
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.

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.
5.2 Description of the LED signals of the Wyze Temp® Plus Probe
LED Color
LED Pattern
Description
Green
Solid for one second
The probe is waking up.
Green
Flashing every four seconds
The probe is awake and
transmitting normally.
Blue
Solid for one second
The probe is going to sleep.
Red
Flashing every four seconds
An error has occurred. This is
likely caused by a weight seen
outside the acceptable range. Try
recalibrating the probe and
verifying that weight is being
correctly reported. If
recalibration does not remove the
blinking red LED and the probe
is otherwise malfunctioning, a
problem has occurred. If you will
contact Matrix, please have the
“error log” value that can be read
under the Advanced tab of the
wand application ready.
Orange
Flashing every four seconds
The probe is in calibration mode.
An orange light informs the user
to remove all weight from the
Wyze Temp Plus Weight Probe,
or that the probe will be
expecting a 100C temperature
sample point if it is calibrating
temperature.
Purple
Flashing every four seconds
The probe is in calibration mode.
A purple light informs the user to
load the known weight onto the
Wyze Temp Plus Weight Probe
Copyright Matrix Product Development, Inc 2014
or that the probe will be
expecting a 0C temperature
sample point if it is calibrating
temperature.
Purple
Intermittent
The purple LED will flash
whenever the Wyze Temp Plus
probe receives an acknowledge
from a base. This indicates a
healthy connection between the
two components.
White
Flashing every four seconds
This pattern occurs when the
“Set Pressure Check On Startup”
option is selected and written to
the Wyze Temp Plus Weight
Probe. This pattern will end,
potentially followed by an error
LED pattern, after 12 minutes.
Putting the device to sleep and
re-waking it after this process
will restore normal operation.
Alternatively, open the battery
compartment and disconnect the
battery for at least 10 seconds.
After this time, use the Wyze
Temp Plus Programmer to
deselect the pressure check
option(the probe does not need
to be powered for the
programmer to work) and then
reapply power by connecting the
battery and closing the probe.

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:
