Works wonderfully. Had Nests till now. Downside is the cost and UI compared to Nest. it’s not even in color but much more expensive. Functionally great.
The thermostat works fine. But the WiFi interface with my cell phone (Resideo) sucks. When there's been a substantial absence (like several months) since I've used the Resideo app, my pin no longer works and I have to install the app all over again. This would be OK, except I can't install the app again because my password is already in the system. So I have to call Resideo so they can uninstall my app, thus allowing me to start all over again. This is very annoying. I've had to do this several times during the last 3 years & 10 months since owning this system.
