The remote thermostat sensor with a sixth sense for comfort
Bring your home to life
SmartSensor unlocks the full power of your ecobee thermostat for enhanced comfort when you’re home and savings when you’re away.
Works with SmartThermostat with voice control, ecobee4, ecobee3 lite, and ecobee3.
Better, balanced temperature
Measures temperature in multiple rooms for maximum comfort.
Comfort where it counts
Detects occupancy and sets the temperature for comfort in the rooms that matter most.
Improved sensor technology
Now with better range and accuracy, and up to five years of battery life.
Comes with two remote thermostat sensors.
All new and improved to enhance every room
The all-new SmartSensor catches eyes and detects both temperature and occupancy—faster and from further away.
Measure temperature beyond the hallway
Place sensors in multiple rooms up to 60 feet away from your smart thermostat to set an average temperature for your whole home.
Fits right in
SmartSensor blends perfectly into the look of any room. Connect it to its magnetic stand and place on a shelf; or attach it to a wall with the included adhesive wall mount.
Better battery life
SmartSensor is powered by the long-lasting CR2477 battery and uses a secure, energy-efficient radio frequency (915MHz) for up to five years of battery life. So, you really can set it and forget it.

When your remote thermostat sensors detect you’re home, your ecobee thermostat automatically adjusts the temperature for comfort, and vice versa for energy savings when you’re away.
Did you know? Smart Home/Away doesn’t run overnight. As you sleep, your thermostat will set the temperature based on the average reading from active sensors.
Follow Me mode
With Follow Me enabled, your room sensors detect which rooms are in use and your ecobee thermostat sets the household temperature to prioritize comfort in those rooms. Over time, your thermostat learns your family’s occupancy habits and adjusts the temperature automatically for smarter comfort and further savings.
How it works
With Follow Me, your thermostat:
Captures the temperature and occupancy readings from each of the active sensors.
Ranks them according to where you’re spending the most time.
Delivers the optimal home temperature.
Follow Me mode in action
The Scenario: It’s a warm summer evening. You’ve recently installed and activated two sensors, one for the living room and one for the bedroom.
You and the kids are spending most of the night in the living room watching a movie. In the middle of the movie, you run to the bedroom to get your phone, triggering the bedroom sensor.
Question: With two room sensors reporting occupancy simultaneously, how does my ecobee smart thermostat decide which one’s readings to prioritize?
Answer: Up until now, you and the kids have spent most of your evening together in the living room. So your ecobee thermostat will continue to prioritize the living room sensor’s occupancy readings and won’t “overreact” to one or two readings from the bedroom sensor.
If you decide to skip the rest of the movie and read a book in bed, your smart thermostat will gradually rebalance the household temperature for comfort in both rooms.
As soon as everyone’s left the living room, the importance of its sensor’s readings will shrink down to zero over the next half hour.
With the Smart Recovery feature enabled, your ecobee uses local weather information, your occupancy habits, and an ongoing analysis of your HVAC system’s heating and cooling patterns so that it’s always the right temperature at the right time.
For example, if you routinely wake up at 6 a.m., Smart Recovery will start your HVAC equipment in advance to ensure your home is at your desired temperature by the time you’re up.
How it works
As your ecobee thermostat gets to know your schedule and your home’s heating and cooling patterns, it learns how long it takes your home to get to your desired temperature. The longer you’ve had your thermostat, the more data it has, and the better it gets at bringing your home to the desired temperature by a specific time.
Keep your home comfortable and prevent your HVAC system from excessive runtime with Thermal Protect. With it enabled, your ecobee thermostat will ignore a sensor when its readings diverge from those of your other sensors beyond a certain customizable limit. (This can sometimes happen when a sensor is placed in a room that tends to get hotter (e.g. attic) or cooler (e.g. the basement) than the rest of the home.)
Setup & Placement
Add SmartSensor with the + button in the ecobee app. Scan the QR code then pull the tab. Follow in-app set up steps.
2a. Place on surface
Using the stand, set your sensor on a surface around 4 feet off the ground and away from exterior walls and windows.
2b. Place on wall
Got curious children or pets? Simply attach your sensor to an out-of-reach spot on an interior wall. (No tools necessary!)
