- Need Ecobee in Home app for automations
- HomeKit cannot find Ecobee during setup
- Ecobee shows as not responding in Home app
- Thermostat paired but commands not working
- Need to remove and re-add Ecobee to HomeKit
Recognize these? Here's what usually causes it.
Common Causes
- HomeKit code not entered correctly
- Ecobee not on same network as Home Hub
- HomeKit pairing data corrupted
- Home Hub iPad or Apple TV offline
- Ecobee firmware needs update for HomeKit

Tools & Requirements
Step-by-Step Solution
Find Your HomeKit Setup Code
Every Ecobee has a unique 8-digit HomeKit setup code. Find it by going to Main Menu on the thermostat then Settings then About then HomeKit. The code is displayed there. It was also on a card in the original box and on a sticker on the thermostat backplate. You will need this code to pair with the Home app. Write it down before proceeding.
Add Ecobee in Home App
Open the Home app on your iPhone or iPad. Tap the plus icon in the top right then Add Accessory. Point your camera at the HomeKit code on the Ecobee screen or enter the code manually. The app will search for your Ecobee. Select your thermostat when it appears. Assign it to a room and give it a name like Living Room Thermostat.
Verify Home Hub Status
HomeKit requires a Home Hub for remote access and automations. This can be an Apple TV, HomePod, or iPad set as a Home Hub. Open the Home app and tap the house icon then Home Settings then Home Hubs and Bridges. Verify your hub shows Connected. If no hub is shown or it shows Disconnected, set up a Home Hub first before expecting full functionality.
Test Siri Commands
After successful pairing, test Siri voice control. Say Hey Siri set the thermostat to 72 degrees or Hey Siri what is the temperature in the living room using your assigned room name. Siri should respond with confirmation or the current reading. If Siri cannot find the thermostat, verify the thermostat name in Home app is simple and clear.
Troubleshoot Pairing Issues
If HomeKit cannot find your Ecobee, first ensure both are on the same WiFi network. Then on the Ecobee go to Main Menu then Settings then Reset then Reset HomeKit. This clears any previous pairing data. After reset, retry adding in the Home app with a fresh code scan. If issues persist, restart your router and try again.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.
HomeKit automations can adjust Ecobee based on time, location, or other device states. Create an automation that sets temperature when the last person leaves home using iPhone location, even if you forget to change it manually.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
