Product Features

A Temperature That's Always Just Right

Get smart temperature control in the rooms you care about most. Choose comfort for the room you want, when you want, or allow comfort to go where you go as you move about your home. The minute your family starts waking up, your T9 Smart Thermostat starts working to get the right temperature in the rooms you want to help you prepare for the day.

Location Based Automatic Adjustments

With the Honeywell Home app and geofencing, the T9 will know when you're coming and going and adjust accordingly. It turns down when you leave to save energy and turns up when you arrive to keep you comfortable.

App to Control from Anywhere

The app allows you to check in and control your thermostat from anywhere using your your phone or tablet. It also sends you alerts if something is wrong, such as an abnormally cool temperature in your home.

People Detection and Smart Response

With Smart Room Sensors (sold separately), the T9 knows which rooms are in use so it can automatically focus on them. Intelligent motion detection algorithms help it tell the difference between someone passing through or spending time in a room, so your ideal comfort can efficiently follow you from room to room.

Helps Everyone Sleep Comfortably

As everyone settles in for the night, the T9 shifts focus to the rooms which you selected as important to look after so everyone's sleeping temperature is just right.
