Wireless Tags now support both Honeywell Home (such as T9) and Total Connect Comfort (commonly known as Honeywell WiFi, such as this) thermostats! Just add them like a regular Wireless Tag from the Wireless Tag web interface or mobile app, like below.

Now you can use the "Set At" option as below to enable temperature monitoring on a Wireless Tag. Automatically, when that tag is reporting temperature too low, heat will be turned on, and if the tag is reporting normal temperature, heat will be turned off.
Also,
thank you support for continuing to developing a great product
