Welcome to Just Right
Get more than a smart home – get smart temperature control in the rooms you want for improved whole home comfort. The T9 Smart Thermostat is simple to install and use with an intuitive touchscreen display. You'll have comfort at home, and can save energy while you're away with geofencing on the Honeywell Home app.
Smart Sensors, Smart Living
When you install Smart Room Sensors, you unlock the thermostat's full potential. You can use the T9's multi-room display to view and adjust the current status of any sensor's location, enabling whole home comfort. And you can prioritize living areas during the day and bedrooms at night for comfort where you want it, when you need it.
Purchase the T9 bundled with a sensor, and expand the system by buying additional sensors separately.
Whole Home Coverage
Thanks to our 200-foot Smart Room Sensor range, you can achieve comfort control for nearly any home using a single thermostat. Bring those important rooms under your control.
Help Everyone Sleep Better
Place Smart Room Sensors in all the rooms you'd like to control and define ideal comfort settings for any time of day. You can prioritize multiple bedrooms at night, so you don't have to compromise anyone's comfort. The T9 can help everyone enjoy a better night's sleep.
Savings When Away,
Comfort When Home
With the Honeywell Home app, geofencing allows the T9 to know when you're coming and going, so no matter your schedule, you can always come home to comfort and save energy when you're away.
Balance Hot & Cold Spots
Set your desired temperature to help achieve more balanced comfort throughout your home. Don’t guess at the right temperature in the hallway to make your bedroom comfortable enough to sleep. Get the comfort you want – to sleep, work, focus, or unwind.
With Smart Room Sensors, the T9 knows which rooms are or aren't in use. Your ideal comfort will follow you and your family over the course of your day.
Smart Response & Alerts
The T9 learns your home's heating and cooling cycles to help deliver the optimal temperature at the right time. Plus, the Honeywell Home app alerts you when it's time to change your filters and when temperatures go outside your threshold.
Smart Home Integration
Full integration with many smart home partners means the T9 can work in sync with nearly any ecosystem you choose, enabling voice control, complex routines, and more.
