Energy Star label

ENERGY STAR® certified product.

The T9 Smart Thermostat gives you comfort knowing your home temperature is always to your liking. This app-controlled thermostat conveniently fits your lifestyle.


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.
