This Smart Thermostat connects to your phone so you can set up sensors to automatically detect the temperature in certain rooms for improved home comfort. With Smart Room Sensors, the T10 can know 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 and your family from room to room over the course of your day. So, if the kids are doing homework or playing while you get dinner ready, everyone will be cozy - and when it’s time to gather, it can keep up. Place Smart Room 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 app to easily focus on rooms either based on their occupancy or according to a specific schedule you choose.
