Almost perfect for what we needed. New construction home that had a Honeywell T6 installed during the build. We decided to upgrade to the T9 for the room sensors, and the ability to program the thermostats to run off a specific sensor during specific times, as well as averaging across multiple sensors. The big disappointment for us is that Honeywell doesnt offer any wall plates for the T9, so we have a hole in the wall next to our new T9, because it is so much more narrow than the T6 it replaced. Despite the number of T9 owners complaining about it and asking Honeywell to offer wall plates, they don't seem to care.
The thermostat performs as expected. I love having the sensors to keep the parts of the house we are in comfortable. I wish the forecast showed more than the little bit it does like other smart thermostats we have had.
Very nice thermostat, easy to install if normal setup. I had to use the c-wire adapter and it was a little confusing going back and forth from the T9 instruction book and the C-wire instruction book. I just wasn't sure, but it all worked. Very easy setup and connect to wifi. I'm glad I bought it.
