This section guides you through the initial setup of your SMLIGHT SLZB-06M adapter, including flashing firmware and integrating with Home Assistant for Matter/Thread functionality.

4.1. Initial Firmware Setup

The SLZB-06M comes pre-flashed. However, for Matter/Thread functionality, specific firmware is required. You can update the firmware via the device's web interface.

1. Access the SLZB-06M web interface.
2. Navigate to the "Mode" section.
3. Select "Matter-over-Thread" as the radio mode.
4. Install the OpenThread firmware as prompted.

Note: Thread firmware for some coordinators is an experimental mode. Use at your own discretion. You will see respective notices on each particular coordinator.

Important: At the time of this video, the Home Assistant add-on for OpenThread works only with a USB connection. For this guide, USB connection is used. Ethernet connection implementation is under development.

4. Click on the device to access its controls.
5. You can now turn the device (e.g., smart plug) on and off remotely using the Home Assistant interface.
6. The device page also displays diagnostic information such as current, energy consumption, power, and voltage.
7. You can create automations, scenes, and scripts involving your Matter device within Home Assistant.

6. Maintenance

6.1. Firmware Updates

The EFR32MG21 and ESP32 chips within the SLZB-06M can be updated remotely without physical access to the device. The ESP32 also supports flashing over USB with an integrated autoflash feature. Regular firmware updates ensure optimal performance, security, and access to new features.

Refer to the device's web interface for available firmware updates and instructions.

7. Troubleshooting

• Pairing Issues: If you encounter issues during the pairing process, double-check that Bluetooth is enabled on your phone and that your Matter-over-Thread device is in pairing mode.
• Thread Network Sync: If the "Sync Thread credentials" process in the Home Assistant app does not immediately show "Home Assistant and this device use the same network", try clicking "Sync Thread credentials" again.
• Experimental Features: Be aware that Thread firmware for some coordinators is an experimental mode. Functionality may vary, and specific notices will be displayed.
• Connectivity: Ensure your SLZB-06M is properly connected to power (PoE or Type-C) and your network (Ethernet, USB, or WiFi) as configured.
• Web Interface Access: If you cannot access the web interface, verify network connectivity and ensure the device is powered on.
