Comfort control Welcome to ‘Just Right’
Sense the temperatures in the places that matter most with the T9 Smart Thermostat. Focus on the rooms you choose by setting a schedule — or let the sensors respond to your lifestyle, helping save energy when you leave and preparing that ideal temp for your return.
Smart Room Sensors (sold separately) Whole home coverage
Place Smart Room Sensors around your home to see each room’s temperature and humidity. Focus on specific rooms you choose or let the sensors focus on rooms people are in.
Sensors reach up to 200 feet, spreading across the home to increase the quality of signal and data sent to the T9 thermostat.
Automatic room control 
Help everyone sleep comfortably
“Alexa, check the temperature of the bedroom.” Focus your T9 Smart Thermostat on specific rooms, such as bedrooms, so everyone can get a cozy night’s sleep.
Requires Smart Room Sensor per monitored area.
Auto home and away mode
With the Resideo app, using geofencing the T9 knows 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.
Your day is in your control
Control the T9 Smart Thermostat however you want. Conveniently manage it using the Resideo app, or use Amazon Alexa, Google Assistant, Apple HomeKit, Microsoft Cortana, Samsung SmartThings, and more.
Honeywell Home app
The Honeywell Home app makes it simple to manage your devices and control home comfort. Get temperature change alerts and filter reminders, and let the T9 automatically respond to when you leave.
People detection
Smart Room Sensors can automatically focus on occupied rooms. Advanced motion detection knows the difference between someone passing through a room or spending time there.
Multi-room focus
Focus on multiple rooms for comfort where it matters most. Don’t guess at the temperature in the bedroom from the hallway. Get the temp you want, where you want it—to sleep, work, focus, or unwind.
Simple setup and savings 
Easy install
Feed your wires into the lettered ports of the wall plate, close the plate, and snap your T9 onto the wall. Then the T9 will self-configure, guiding you through a simple setup.
