I just had a new furnace installed and along with it a Honeywell T6 Pro Smart thermostat. Progamming the thermostat on the thermostat is a real pain, so I was looking forward to using this App. Well, on a Samsung Tablet, the app cannot tell that I have turned on airplace mode as instructed and turned on location as instructed. So it keeps telling me to turn them on. Finally I got the app to see the thermostat, but as the thermostat will not connect to my home wifi, I cannot use the app to program it. Tomorrow, I will contact the installer and get them to remove the Honeywell thermostat and re-install my Nest. i don't like Google much but at least their browser-based application works. This app is a frustrating waste of time.
