Great Addition to T9 Thermostat. Being able to see and adjust, the humidity and temperature levels in each room really brings out the best of Honeywells T9 Thermostat. The app works great as well, and is very easy to use and compatible with Google Home, Apple Home, and many IFTT devices. I got four for my house and would recommend to anyone getting the T9 thermostat.

I have bought a few of these to place around the house and plan to buy more. I’ve set them up in Apple home and use it to create automations for turning lights on and off when we go into rooms in our house, it’s nice to add value. They are very easy to sync to the thermostat.

Works very well with your thermostat and app. I have had it about a month and it lets me know what temp my room is running. I keep it upstairs in my tri level home and usually run 1-2 degree difference but not I can keep the home on a average temp so the whole house feels the same.

This remote sensor works very well and is needed to better control the temperature in my office and the rest of the home. It would be better if it were half the price though.

I have 5 of these scattered around my house with the Honeywell T9 thermostat. The temperature is very accurate and the range is excellent as well. I used to set my temperature in house at 66F with a brand new unit. Now it’s set at 72F with new thermostat and these sensors. I highly recommend replacing your old thermostat. I will save you money plus it won’t over work your ac unit. Can’t wait to see my savings
