Ecobee SmartSensor Not Pairing or Reporting Temperature

Ecobee SmartSensors extend thermostat awareness for temperature and occupancy. This guide covers pairing and reporting issues.

Sensor Not Pairing

1. Remove battery tab to activate sensor
2. Put thermostat in pairing mode first
3. Sensor and thermostat must be within range
4. Wait 2-3 minutes for pairing to complete
5. Try removing battery and reinserting

Sensor Showing Offline

1. Check battery level (CR2032)
2. Replace battery if level is low
3. Move sensor closer to thermostat
4. Maximum range is approximately 45 feet
5. Walls and floors reduce range

Temperature Readings Wrong

1. Allow 15 minutes after moving sensor
2. Avoid direct sunlight on sensor
3. Keep away from heat sources and vents
4. Sensor offset not adjustable (factory calibrated)
5. Compare with separate thermometer

Occupancy Not Detecting

1. Occupancy uses PIR motion detection
2. Mount at 5 feet height for best detection
3. Aim sensor toward room center
4. Large furniture may block detection
5. Detection range is approximately 15 feet

Follow Me Feature

1. Enable in ecobee app Comfort Settings
2. Sensors participate in Follow Me must be selected
3. Thermostat averages temps from occupied rooms
4. Occupancy determines active sensors
5. Takes time to learn occupancy patterns

Door/Window Sensor Specific

1. Includes contact sensor for open/close detection
2. Can pause HVAC when window open
3. Configure alert threshold (how long open)
4. Magnet and sensor must align properly
5. Also reports temperature like room sensor
