Outstanding hardware. Beautiful, easy to use and accurate. The utility of adding additional sensors is a game changer. Would be 5 stars if it included support for Matter.
I would recommend this to a friend!

Still learning

We are still learning how to control the T9 when two family members both have the Resideo app on their phones. I set the temp on my phone before I left the other day but for some reason it did not take effect. My wife set it from her phone and it worked. Plus doing a temp increase or decrease on the T9 is something I have not figured out. I woke up one morning and the house as at 67 degrees (this is summer in Texas) and I could not get it to stop. I ended up using the Resideo app to reset the schedule and had to create the schedule again. It was as if someone (we did have a guest that night) set it to a constant cool. But I don't know how one could do that from the the wall thermostat. Like I said, we are still learning how to use this. I'll look on youtube for possible instruction videos.
No, I would not recommend this to a friend.

Overall, a good thermostat

The thermostat device is great with a lit display in which you can also adjust for nights. Desired improvements.. first, being able to see remote temps on the main screen or have a setting that provides this option. For the android app, it would be nice to see the equipment status how it shows on the main thermostat.. especially for 2 stage units. Otherwise, I'm liking this new device which I've owned for 1-2 months now.

Helps keep my 2 story house at a consistent temperature throughout. I only wish the fan was able to be set to cycle when the temperature varies too much. I current can only cycle. I also wish I was able to easily see both temperatures from the thermostat and sensor on the dashboard.

Liked nest better but it wouldn’t connect to my WiFi. The app doesn’t display the correct temp for several moments.

The thermostat works very well. The only thing I wish it had was the ability to set your own schedule for your furnace fan.
