Unfortunately, not all Ecobee thermostat models are compatible with HomeKit. 

When your Ecobee thermostat is not working with Homekit, then one of the fundamental things to inspect is if the model is compatible with the HomeKit.

In order to simplify, all Ecobee models except EMS, EMS SI, Smart, Smart SI, and earlier Ecobee3 are compatible with Homekit.

You can also verify that your thermostat works with Homekit by looking for the Apple HomeKit logo on your Ecobee thermostat packaging. If the model is compatible, keep reading further!

Note: If you have an incompatible Ecobee thermostat, you cannot set it up with HomeKit!

3. Uplift the WiFi Internet Connection

The central link between the thermostat and your HomeKit setup is a reliable and high-speed internet connection.

HomeKit completely relies on a stable internet connection to communicate with your Ecobee thermostat so any fluctuations or other issues might impact the performance!

• The solution is to verify the internet on both devices!

How to Justify the Network on Your Ecobee?

1. First, open the Ecobee app.
2. Next, tap on the Menu icon.
3. Scroll down and select About.
4. Locate and press on the WiFi.

2. Scroll down to find “WiFi” or “Wireless”. 
3. Check the SSID of the connected WiFi.

Note: Ensure your both devices are connected to the same WiFi network!

 Ways to Optimize the WiFi Network?

• Power cycle your WiFi router by stopping the power!
• Disconnect and reconnect the WiFi on your mobile.
• Ensure that your WiFi internet subscription is active.
• Test the same internet connection on other devices.
• Unpair devices from the WiFi to free up bandwidth.
• Prevent any active VPN from altering your IP location.

Tip: If you notice any problem with your internet connection on other devices as well, then contact your ISP for timely network restoration. 

4. Power Cycle the Entire Setup!

Normally, smart devices can frequently encounter electrical or software glitches that might affect the device’s performance.

This is why one of the most powerful ways to address the problem is to power cycle both the Ecobee thermostat and your HomeKit hub or smartphone host device.

How to Power Cycle Your Ecobee?

1. Securely hold your Ecobee thermostat.
2. Pull off the thermostat from its base.
3. Then, wait for about 30 to 60 seconds
4. Reattach the thermostat to its base.

How to Power Cycle Homekit Hub?

✅ For Apple TV or HomePod

Unplug your unit from the power source for about 60 seconds, and then plug it back in.

✅ For iPad

Long press and hold down the power button until the power off slider appears on the screen and slide to the right to power off.

Reminder: When both your devices are power cycled, re-attempt to establish the link by following the steps in the very first solution in the guide.

5. Replace the Thermostat Battery!

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 192.168.0.1 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.
7. Finally, Save the changes and then reboot the router.

Reminder: Don’t forget to verify that both your Ecobee and HomeKit are connected to the same WiFi, otherwise the setup wouldn’t work.
