This thermostat was installed by the builder of our new home, so it was in and working when we moved in. I did have some difficulty with the WiFi connection, but once I spoke with a technical support representative, it has been working flawlessly.
The unit won't stay connected to WiFi, the app lags and now the temp reading is totally inaccurate, leading to our AC unit running for way longer than necessary.
The thermostat does the job. Several times a week the thermostat goes off line. The app does not work well with 3 people using the geofence. I could have bought a cheaper unit for the bells and whistles that I don't use.
