Easiest to use smart thermostat I could find. The thermostat itself works like a basic digital thermostat. No unnecessary bells and whistles. Easy for everyone to use. The Android app is very easy to use, has extra featyres, and has the ability to set thermostat to Auto mode for engaging cool/heat automatically as needed to keep temperature within a comfortable range. Can lock thermostat from app to keep others from messing with it. Can enable percentage per hour to run blower only. This is great as the comfortable outside temperature seasons can be long and the air would get stail in our house since the unit never runs during this season. Had trouble setting it up with multiple phones controlling. Lost wifi during this time. Performed a reset of the thermostat and set up again. Has been 2 months and no issues, no disconnects. Connected to Ubiquiti hotspot.
