At the time of this video, we were unable to pair Matter-over-Thread device via iPhone. 2. Install `Google Home` app from Play store. It is recommended by `Home Assistant` developers and we were not able to pair our Thread devices without installed Google Home app. 3.

In app, go to `Settings` – `Companion app` -> Click `Troubleshooting` and click `Sync Thread Credentials`. 5. Wait until message `Home Assistant and this device use the same network`. If you see another message, namely `Added network from Home Assistant to this device` – you need to click on `Sync Thread Credentials` again, until you get that message about the same network. 6. If you are not getting message `Home Assistant and this device use the same network` - try to reset your Google Play Services (remove all data, usually by App settings -> Erase data -> Clear All Data, but namings depend on the smartphone model). ### Adding the Matter Device 1.

It should pass through this satuses: - Connecting to device... - Generating Matter credentials... - Connecting device to network... - Checking netwoek connectivity... - Connecting device to Home Assistant... - Device connected! 7. Note: - If a Matter-over-Thread end-device has been powered up for a long time, it may require a reset of device to put back into pairing mode. - In case you have Google home devices (Nest hub) and experiances issues with pairing, try to turn them off before starting OpenThread Border router add-on on your Home Assistant and your Home Assistant app. ### Verifying Connection and Control 1. Once the pairing is complete, head back to the Home Assistant interface. You should see your Eve Energy socket listed on your `Dashboard` or under the `Devices` section . 2. Click on the device to access its controls. You should be able to turn the socket on and off remotely within the Home Assistant interface. **Congratulations**!
