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...

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.
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.

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.

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.

Worked great for a few weeks. It was awesome having control from anywhere. All of a sudden i was getting alerts every day saying the system was offline, then online, then offline again. I reset the wifi connection which didn't help. There have been no changes that could have affected it. Probably going to remove it and go back to a regular 'dumb' thermostat.
No, I would not recommend this to a friend.

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.
