The T6 was recently installed in our cabin so that we can monitor and control temp while away. The thermostat is easy to set, and the app very easy to use. We have an ecobee in our primary home and I definitely prefer the Honeywell T6. The only thing I wish is that the Honeywell T6 would allow for a second temp sensor, like the Ecobee offers, to help better balance temps throughout the space.
It is very handy to have. We were gone on a vacation for two weeks in winter. Put the temperature down while we were gone we could monitor the temperature inside and outside of our home from our place of vacation Then as we were on our way home 1 hour before we got home we could adjust our temperature back up to a cosy temperature so when we arrived it was comfortable inside our house Wendell
When ever you change the temperate, the system automatically does a hold (which pauses the schedual). The system should be more user friendly. There is a learning curve to it.
