Solid unit and easy to use. I would buy again. It connects nicely to the app but you must get the correct app. The app is NOT called honeywell but Resideo which doesn't appear anywhere on the unit itself. We use this in a small commercial setting.
We have two homes - one with the Nest and the 2nd with Honeywell’s T6 Pro Smart Thermostat. After the great experience with Honeywell, we immediately removed the Nest in our second home, The thermostat is so straight forward! The support from Residio is also outstanding, as it their IPad app.
