The firmware/software for this product is not very stable. There are many 'WiFi Disconnects' and I know our internal WiFi is quite stable. Additionally, the fact that you can not control the thermostat from a Windows PC is not ideal. Honeywell only provides an app for Android and iPhone. We use an external temperature sensor with one of the thermostats to control a dual fuel configuration (we have 4 Honeywell stats in total). The thermostat doesn't show external temperature or we heat source it is calling for .... very weak!
Well pleased with the thermostat, It is were easy to work and seems to keep the house steady, whether warm or cool depending on the temperature outside.
Easy to use, reassuring, excellent memory function

The app is convenient and provides reassurance. The wall unit is solid. Recently had a 2-day power outage, and the unit came back on with no intervention from me, remembering the programmed schedule and other settings. Again, very convenient.
