Windows Management Instrumentation Temperature Monitor

Given a WMI Identifier (e.g. the one for your CPU), this applet will query the temperature and change the color based on a configurable scale. This applet requires Open Hardware Monitor to be installed and running to work properly. Download OHM from their website: https://openhardwaremonitor.org/.

How to find your WMI identifier

1. Open up a PowerShell prompt. One way to do this is to open the start menu and type PowerShell.
2. Type Get-WmiObject -namespace "root/OpenHardwareMonitor" -Class Sensor -Filter "SensorType='Temperature'"
   That will present you with a list full of entries like this (assuming you have OHM set up properly):

__GENUS          : 2
__CLASS          : Sensor
__SUPERCLASS     :
__DYNASTY        : Sensor
__RELPATH        : Sensor.InstanceId="3891",ProcessId="39315c09-3d8a-41ad-ae2e-9e25862b92b5"
__PROPERTY_COUNT : 10
__DERIVATION     : {}
__SERVER         : YOUR-COMPUTER-NAME
__NAMESPACE      : root\OpenHardwareMonitor
__PATH           : \\YOUR-COMPUTER-NAME\root\OpenHardwareMonitor:Sensor.InstanceId="3891",ProcessId="39315c09-3d8a-41ad-ae2e-
                  9e25862b92b5"
Identifier       : /lpc/nct6791d/temperature/0
Index            : 0
InstanceId       : 3891
Max              : 64.5
Min              : 28.5
Name             : CPU Core
Parent           : /lpc/nct6791d
ProcessId        : 39315c09-3d8a-41ad-ae2e-9e25862b92b5
SensorType       : Temperature
Value            : 41
PSComputerName   : YOUR-COMPUTER-NAME

3. Identify the entry you're most interested in. For my CPU, the above entry is the correct item. I found the Name field to be most useful.
4. Copy the Identifier field. In the above example, it is /lpc/nct6791d/temperature/0.
5. Configure the applet's WMI Identifier field with this value

FAQ

1. Can I use this for WMI values other than temperatures? Effectively, yes. Once the number ranges and color spectrums are configurable, you could in theory use this to show status on any numerical WMI entry's value by configuring the identifier to the desired entry.
2. Will you make a Linux/MacOS version of this? Not likely as I don't use my keyboard on other platforms and thus testing would be arduous.
