The thermostat does not seem to read accurately, I have followed all the trouble shooting tips and nothing seems to work. The remote sensor seems to be reading accurately.

Thermostat failed, replaced with Google Nest. Could not get it reset after an electrical outage that lasted 5 days in Colorado.

Limited features

Verified Purchase:Yes
Geofencing doesn't work well, as it only changes the status when it's opened. I also find the lack of being able to see how much the furnace and air conditioning have been running to be problematic. It's easy enough to change the settings, but that's where the ease seems to end.
No, I would not recommend this to a friend.

Great thermostat
on March 9, 2026

Verified Purchase:Yes
This thermostat offers great features. It has an outside temperature reading & is color coded with the function of your furnace. The panel temp number turns blue when the air condition is on & orange when the heater is blowing. You can put several sensors around the house & select multiple rooms for an "average temperature" to set parameters. I rate this a 5/5 stars & definitely will recommend this thermostat to my family/friends.

Thermostat is easy to operate.
Only problem I have is with the light that is 24 hour on. If you have thermostat in your bedroom, there is a problem.

Self installed . Not difficult if a basic understanding of furnace wiring location. Well detailed instructions. Just flip circuit breaker first. Works very well for adjusting when away from home.
I would recommend this to a friend!
