Ordinary thermostats read the temperature in just one room (usually the hallway). That can make things uncomfortable in important rooms like your bedroom. That’s why we created ecobee3. It works with room sensors to deliver the right temperature to the rooms that matter most. Our room sensors detect temperature and occupancy. Are you reading in bed or watching the game downstairs? ecobee3 knows and delivers comfort to the right place at the right time.
