So for folks who are facing and issue with the thermostats stop communicating randomly with the ST hub (due to the buggy firmware please report it to ST support first), we found a quick fix for it.
Till now you had two options, you can try the 10 minute cold reboot or exclude and re pair the thermostat.
But here is a easy way to reset it without losing your settings or starting over.
Open the thermostat top cover and there is a reset button. Press it for 15 seconds. Now open the ST app and click on the refresh tile to resync all the settings. Done!
