ecobee SmartSensor 2-Pack – Temperature & Occupancy Sensor

Comfort where you need it most: SmartSensor detects which rooms are occupied and shares temperature readings with your ecobee Smart Thermostat from up to 60 feet away—even through walls and floors—so your home adjusts for the rooms you actually use, not just the hallway.
Bedroom comfort: Place a SmartSensor in your bedroom, and your thermostat will prioritize that room’s temperature overnight instead of relying on one reading from elsewhere in the house.
Save energy when you’re away: SmartSensor detects when rooms are occupied and helps your thermostat adjust automatically, reducing energy use when your home is empty while keeping comfort ready when you return.
