The thermostat is fine itself. I am a heating contractor and had a very difficult time getting it to work on a remote app. The android version wouldn't connect properly and my older iPad couldn't handle the app. It wasn't until we had s new iPhone
The AirMax person came out to clean our furnace for fall. He had one in his truck. When we travel we can use it to check temperature in house. Very nice man and installed quickly.
The device often seems to have trouble connecting to our wi-fi, though we haven't found issues with the wi-fi. I have had to reset the wi-fi 3 times on the thermostat and we have had it for less than a month.
I have 100 MB fiber optic internet with an AC1750 WiFi router. It is NOT compatible with a router with a high speed. I purchased an older model compatible router and it still doesnât work with the WiFi. Waste of money. I canât use it remotely.
