Sometimes the Ecobee thermostat resembles pairing issues due to power insufficiency or electrical fluctuations.

If you are sure that your thermostat is plugged into a functional outlet and is getting a full power supply then it is a good idea to take a look at your unit battery level.

Low batteries can reduce device performance and prevent it from working with the Homekit hub.

  • Ecobee Sensor usually lasts up to 2 years and Smart Sensor lasts up to 5 years!

The Ecobee sensor uses the CR2032 and CR2477 batteries that you can easily purchase from Ecobee manufacturers or other retailers.

These batteries are not rechargeable and that’s why you have to replace them to maintain your Ecobee thermostat efficacy and optimal performance.

How to Replace Ecobee Thermostat Batteries?

  1. First, gently remove the cover from the back of the sensor.
  2. Take out the previously installed battery from the sensor.
  3. Insert a new battery with the positive side facing out. 
  4. Securely embed the battery into the device’s compartment.
  5. Finally, reinstall the Ecobee thermostat battery cover back on.

When everything is sorted then check to see if your Ecobee thermostat works with Homekit!

6. Switch the Network Frequency

The Ecobee thermostat supports 2.4 GHz and 5 GHz network frequencies.

However, it is very crucial to choose a compatible frequency channel depending on the distance between both devices and your WiFi router. So, reconnect your devices accordingly:

  • When your setup is far away from the router, connect to 2.4 GHz.
  • In contrast, if you’re close to the router, feel free to use the 5 GHz.

How to Switch the WiFi Network Frequency?

Tip: If you already have both WiFi frequencies online, skip the steps below!

  1. Begin by opening a web browser on your PC.
  2. Enter to access your router settings.
  3. Sign in using admin/admin or admin/password.
  4. Then, locate and enter into the Wireless Settings.
  5. Then, search for the Wireless Network Frequency.
  6. Choose 2.4GHz or 5GHz according to the situation.
