It works as advertised except when I added my wife to the geofence and it hasn't recognized when she is in or out of the fence. It definitely could be a setting on her phone.
I am constantly using the app or checking out the wall unit. Not because it’s does not hold a temp but because I just find it cool to be monitoring or changing the room temp from away. The wall unit looks great also! I love it.
Excellent when you need to keep a room at a comfortable temp, but the thermostat is in the hall way. And love the smart app, and smart home integration.
