Ecobee Not Averaging Sensors? Here’s How to Fix It

by

If your Ecobee thermostat isn’t averaging your temperature sensors correctly, you might notice uneven comfort across rooms or find the system heating or cooling based on just one room. This can be frustrating, especially if you invested in multiple sensors to get more accurate readings.

Luckily, this issue is often due to configuration settings or a misunderstanding of how sensor averaging works. Let’s walk through what causes this issue and how to fix it step-by-step.

💡 How Sensor Averaging Works on Ecobee

Ecobee allows you to use multiple temperature sensors throughout your home to create a more balanced average temperature. This average is what your HVAC system uses to determine when to heat or cool.

The thermostat only averages the sensors that are:

  • Assigned to the active Comfort Setting (Home, Away, Sleep)
  • Currently detecting occupancy (depending on the setting)

If a sensor is excluded from the comfort setting or not detecting occupancy, it may not be included in the average.

🔍 Step-by-Step Troubleshooting

Check Comfort Settings and Sensor Participation

Go into your Ecobee settings and make sure your sensors are properly assigned:

  • Tap Menu > Settings > Comfort Settings
  • Select the current mode (Home, Away, Sleep)
  • Under “Participating Sensors,” ensure the sensors you want to average are checked

If a sensor is not checked, it will not be included in temperature averaging.

Verify Sensor Connectivity

If a sensor has gone offline or has a weak signal, it won’t be included in the average.

  • Go to Menu > Sensors
  • Check the signal strength and battery icon for each sensor
  • If the sensor is disconnected, move it closer to the thermostat and replace the battery if needed

Disable “Follow Me” If Necessary

The “Follow Me” feature adjusts the average based only on rooms that are currently occupied. If a room is unoccupied, its sensor might be excluded even if it’s assigned to a Comfort Setting.

To disable “Follow Me”:

  • Go to Menu > Settings > Preferences > Follow Me
  • Toggle it Off if you want all sensors to always be included in the average

This ensures a true average regardless of occupancy.

Reset Sensor Configuration

Sometimes, resetting your sensors and re-adding them resolves unexpected behavior.

  • Go to Menu > Settings > Sensors
  • Remove and re-pair the problematic sensor
  • Reassign it to the correct Comfort Settings

Update Firmware and App

Ensure your thermostat and app are running the latest version:

  • Go to Menu > About to check the firmware version
  • Update the Ecobee mobile app via your device’s app store

Bug fixes in updates can resolve averaging issues and improve performance.

Restart Your Thermostat

As a last resort, try a simple restart:

  • Gently pull the Ecobee thermostat off the wall
  • Wait 30 seconds
  • Reattach to reboot the system

This often clears temporary glitches affecting sensor readings.

✅ Final Thoughts

If your Ecobee isn’t averaging your sensors properly, start by reviewing your Comfort Settings and checking sensor participation. Disable “Follow Me” if you want all sensors to be always included, and check for connectivity issues. With the right setup, your Ecobee should balance temperatures across your home just as intended.
