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.
Your home’s comfort at your fingertips: Get a complete view of your home’s temperature and occupancy, then adjust settings room by room from the ecobee app—whether you’re on the couch or away.
Flexible placement with effortless setup: Everything you need is included in the box. Simply place your SmartSensor on a stand or mount it to the wall, then connect it to your ecobee thermostat in the app. No wiring, no tools, and no professional installation required.
Added awareness when you need it most: SmartSensor detects unexpected motion when your system is armed and can send alerts for added peace of mind, helping you stay aware of what’s happening at home. Requires an active ecobee Smart Security subscription.
Personalized comfort in more rooms, right out of the box: Includes two SmartSensors so you can prioritize the spaces you use most and create a more balanced temperature experience throughout your home.
Built to last for years: The included CR2477 battery delivers up to 5 years of reliable power, giving you effortless room-by-room comfort with minimal maintenance.
