We had 2 T6s installed both work fine, but the WiFi on both keeps dropping their signal for 20-30 min. each day, but it reconnects itself with no problem.
Things should be simple, efficient, easy to install, easy to use - and all of these should actually work the way you would expect without experimentation or desperate hope. This device does all of that flawlessly, as if designed by the consumer!!
I am not happy with the new app. I am also not happy that I can not use any of the old thermostats with the new app or the new thermostats with the old app. I don't like that I have to have 2 different apps to control the different stats.
We already had a older programable thermostat that worked OK. The contractor installed this one with a new system. The new one is far too complex, I don't use or need most of the features such as WIFI.
