I really like the functionality of the Honeywell - particularly its integration with Google Home. That being said, I'm only giving it a 4 because it's ugly as hell. Black and white with a boxed design...improve the UI and form factor please!
This thermostat isn't as smart as it claims to be. It doesn't want to follow the morning schedule. We set it at 68 degrees and it runs our furnace for 2 hours in the morning to bring it up to 70 degrees.
The T6 pro is great. Very nice to be able to set it and forget it. Gone are the days of getting settled into bed then wondering if someone remembered to adjust the thermostat. Super easy to enable vacation mode and adjust remotely with the app.
The thermostat itself is great, and the contractor did a great job physically installing it. However, the install process syncing up the apps with the unit were unnecessarily complicated and irritating.
