The T-9 has the ability to connect to a wireless sensor. This allowed us to monitor a few rooms in the space and keep the temperature at a more comfortable level. The thermostat and sensors were easy to install. The Resideo APP works perfectly and makes the whole temperature management process very easy.
We have radiant floor heat with 5 zones. One thermostat was installed in an area mostly covered by a different zone. We replaced that thermostat with the T9 and placed the remote sensor in the proper location and everything is great!
The programming and scheduling is a plus and works well. One of the main reasons I purchased was to control temperature in my sons room as opposed to the hall way - this feature works okay but sometimes loses connection to the remote sensor even though it is 10ft away. Additionally, the run time data has not uploaded to the app since the day I installed it which was a disappointment. Looking online about this issue, several people have complained about this and Honeywell has not done anything to resolve it.
No, I would not recommend this to a friend.

Easy, flexible and user friendly. I just had to plug and use with my existing thermostat mounting. The device gives me all the options I need. I really like the ability to control my thermostat from afar through wifi. I just wish my othe system could take a wifi connection, but I will have to wait until I upgrade my heat pump. I will buy this device again when the time comes.
I bought this T9 thermostat with a remote sensor so i can control my kitcen temperature but have the thermostat installed by the heater. It was easy to install, looks great, and very user friendly. I liked it so much that i bought a second T9 to replace a Honeywell RTH8580WF in the hallway by my bedroom. The new T9 remote sensor is in my bedroom, where I need the temperature to be controlled, especially at night. I lalso love the ability to contril both thermostats from my Residio phone app.
