has had the thermostat for a month. seems to be working fine so far. I love the app and the interface and ease of use. The only slight negative is the mechanism inside the thermostat that turns the a/c on( click sound) is somewhat loud.
I just installed central hvac in my cottage with a T6 WiFi thermostat. It’s perfect for me because I can control the heat and air 150 miles from my base house using my smartphone, so I can have it cool or warm well before I get there, I love it. Norm K.
