I have an older house(1918) which is challenging. With the room temp sensors and being able to select different rooms as priority is key to me balancing out my new system.
I would recommend this to a friend!

It's great! Did have a little bit of trouble installing the C wire adapter but now it's working and doing just what I need it to.

Thermostat is great, software sometimes glitches.

My only problem is sometimes the geofence doesn’t know I’m home. I have to go into app and turn it off and on. Not sure if it is a WiFi in my home or a glitch in Resideo app. I invited wife and it works perfectly for her when she comes and goes.
I would recommend this to a friend!

Limited features for such an expensive T-Stat

Not dual fuel compatible. User doesn’t have complete control over system. Too expensive to be so restrictive!
No, I would not recommend this to a friend.

Been having problems for years with different temperatures between front rooms near thermostat and rooms at the back of home. This thermostat with the sensors keeps my home at a comfortable temperature.

So far so good. My last Honeywell stat died on me.. The one thing missing, T9 should be able to control the air ex-changer like the Ecobee does...

Thermostat replaced my outdated Nest Thermostat. Works fine and like the geofence feature. Only thing that would be nice is that the screen on the thermostat stays lit all the time. Would be nice if it darkened when not looking at it to adjust it.
No, I would not recommend this to a friend.
