Hi there! If you’d like to bind your Smart Lock U400 to Home Assistant, please follow the steps below:
Binding Procedure
- Press the Set button once on the lock.
This is enough to wake the pairing mode—as soon as you hear any voice prompt, the lock is already in pairing mode.
There’s no need to enter the setup menu or press 4. - Open the Apple Home app, go to the U400 device settings, and tap “Turn On Pairing Mode” to generate a new Matter pairing code.
- Use the generated Matter code to add the U400 to Home Assistant.
Networking & Environment
- Same Network: Your iPhone and Hub must be on the same Wi-Fi network.
- Bluetooth: Keep Bluetooth ON on your phone during the entire process.
- Proximity: Stay close! Keep the lock within 5 meters of your Thread Border Router (e.g. a Raspberry Pi 4). If there are walls in between, try to stay within 3 meters.
