Ecobee Sensor Thinks Room Is Occupied[Why and How To Fix?]

The Ecobee sensor sending false occupancy readings has problems. Assess the accessory device for proper installment and pairing with your thermostat.

Check the sensor for any dents or hardware damage. Examining the hardware before going to the intrinsic part of solving the issue is necessary.


Due To Low Battery

Your Ecobee sensor sending a false occupied signal can be because of its low battery. There are two Ecobee sensors: the room sensor and the smart sensor. Both have the faculty to pair your thermostat to detect temperature and motion in a room for high efficiency.

The room sensor uses a CR-2032 coin battery with a 1-year life expectancy. While the smart sensor uses a CR-2477 coin cell battery with approximately a 5-year life expectancy.

Learn to replace your Ecobee sensor batteries with these steps:

Replacing Room Sensor CR-2032 Battery

  1. Hold the sensor stand gently and pull the sensor up to detach.
  2. Use a thin-edged object like a plastic card to poke out the battery.
  3. If you're using the round battery cover, simply slide the tool into the holed points of the battery cover to lift out the battery.
  4. Insert the new battery with the positive side showing or outward.
  5. Give a little push for the battery to settle in the sensor body.

Replacing Smart Sensor CR-2477 Battery

  1. Open the battery cover using the side of your thumbnail or any thin-edged tool.
  2. Slip out the battery or turn it upside down with a little shake to remove the battery.
  3. Insert the new battery with the positive side showing or outward.
  4. Put back the battery cover by giving it a little push to completely close.

Due To Location

Another reason can be the location of your Ecobee sensor. Make sure to place your sensor around within the recommended range to get a stable signal.

Obstacles like thick walls, traffic areas, and devices with the same frequency can lower the range. You can mount it to the wall five ft. above the ground. Place it far from a window or heat source.

Look at the range capacity and viewing angle of your Ecobee sensors below:

Room Sensor Range Capacity

  • Range: approximately 45 ft. from the thermostat
  • Viewing angle: up to 120 degrees horizontal; 25-30 degrees vertical

Smart Sensor Range Capacity

  • Range: 60 ft. from the thermostat
  • Viewing angle: 140 degrees horizontal; 100 degrees vertical
  • Occupancy sensor: 20 ft. 

Best Place For Your Ecobee Sensor

You've been trying to test where is the ideal place for your Ecobee sensor to make the most out of it. Put the sensor where activities happen often, and there's extreme temperature. A thermostat has about 32-sensor compatibility.

So, getting and placing your sensors in as many strategic places in your house can let you experience the best comfort.

Here are specific places to put your Ecobee sensor to unleash its full potential:

  • living room
  • nursery or baby's room
  • kitchen
  • bedroom
