The T9 Smart Thermostat works with Smart Room Sensors to help you adjust the temperature from anywhere and stay cozy in the rooms that matter. Place sensors where you want to see each room’s temperature and humidity. Use the multi-room display on the thermostat’s touchscreen — or in the Resideo app — to focus on rooms based on occupancy or a specific schedule you choose. When focusing on multiple rooms, the T9 works toward creating an average temperature, balancing the needs across the whole home.
This bundle includes one Honeywell Home RCHT9510WF T9 Smart Thermostat and two Honeywell Home RCHTSENSOR Smart Room Sensors.
LIVE AND SLEEP SMARTER. Choose the temperature in a specific room, like the bedroom, to be exactly what you want it to be, to help get a better night’s sleep. Or let the Smart Room Sensors automatically detect which rooms people are in and focus comfort where it matters automatically.
AMAZING SENSOR RANGE. The battery powered Smart Room Sensors utilize unique Honeywell Home technology to deliver an efficient signal up to 200 ft range. (Could be further depending on home construction).
MULTI-ROOM FOCUS. Don’t be forced to choose one room over another, the T9 Smart Thermostat and Smart Room Sensors can handle multiple rooms to focus on.
ENERGY STAR certified. Help save energy, track your heating and cooling with monthly energy reports and get personalized tips on reducing energy use.
CONTROL IT YOUR WAY. Control the T9 using the Resideo app or through Amazon Alexa, Apple HomeKit, Google Assistant, and more.
SAVE MONEY AND ENERGY. Adjust your ENERGY STAR certified thermostat from anywhere with your mobile device, or let your home automatically react to your schedule with Auto Home/Away Scheduling. Save even more with possible inclusion in energy saving schemes from your utility provider. (Subject to availability in area)
DO IT YOURSELF SIMPLE INSTALL. With guided installation setup couldn’t be simpler. The included power adapter is an easy-to-install, low-voltage alternative to a C-wire, so the thermostat is compatible with most homes.
COMPATIBLE WITH: Forced air (gas, oil or electric), hot water and steam, and heat pumps with electric backup. Does NOT work with electric baseboard heat (120-240V). C-Wire Required.
Before purchasing, check to see if this thermostat is compatible with your home and to determine if your home needs a C-wire power adapter.

Simple to use – easy to install thermostat with remote sensors
My thermostat was installed out in the hall and not in either of the rooms I occupy. This thermostat and its remotes has allowed me to run the thermostat using one remote or the other depending on where I am. It works through an app that allows you to turn on and off the heat/ac and to choose which remote to use (or combinations of sensors).Installation was easy and the app is pretty simple and effective – it comes with lots of tools and tips to help install it on all kinds of systems. Fortunately, for me the defaults all just worked. The only problem is that there are several deceptively named apps in the Apple Appstore that sound like the right thing, but aren’t. As long as you get the right one – “Resideo” all will be well.

Super easy to install, easy to use, quick tech support through Facebook
I’ve never really done any electrical work, but this was super easy to install and kinda fun! It comes with an adapter, so I was able to just return the other adapter that I bought. Great product!My only complaint is that the name of the company has changed, so the inconsistency between the name on the thermostat and the actual company now was a bit confusing to set up the online account. Doing the physical setup was easy, doing the online stuff was a hassle. When that is finished though, the product works great, and tech support was also really quick to respond!

Simple, reliable, effective; app works great.
I installed it easily, and well after that have now had zero complaints. The app seems bug free and does everything I can think of to ask of it. No potential privacy issues. A good deal.

Hit or miss
I bought one for my living room and never had one single problem with it. Got a second for my room and it was already registered, returned it and was sent another that was registeredâ¦Iâm assuming Amazon is to blame, but Iâm not certain the company didnât send them back out as new without wiping them. It is nice that you can use sensors, I had major issues bc my house has two hvacs, and my daughters rooms were freezing in the winter and hot in the summer prior to buying the one that worked. You can also control it using Alexa, so thatâs a nice feature.

Great thermostat… Small glitches
This thermostat was easy to install (I’m tech savvy) and works very well. I do like the satellite feature and the app to control the settings from anywhere. The temperature averaging did help the overall temperature in the house until we got the ducting fixed… Now it works even better.If you need geofencing reliably this may not be the product for you. I have never had it work reliably. However, it may be because some of the connected devices are cheaper/older phones. It may work more reliably with newer higher end devices.
