Instant Answers to Common Questions
This FAQ applies to all devices in the SLZB-06x/MRx series, including SLZB-06, SLZB-06M, SLZB-06P7, SLZB-06P10, SLZB-06Mg24, SLZB-06Mg26, SLZB-4G, SLZB-MR1, SLZB-MR2 and SLZB-MR3. For simplicity, we refer to them collectively as SLZB-06x/MRx series devices throughout this section.
They support various connection options like Ethernet, USB, Wi-Fi, and PoE, and come pre-configured and ready to use. Whether you want to control your devices locally, remotely, or even without a separate smart home server these adapters offer a reliable, flexible way to build and expand your smart home.
They come pre-flashed and tested, so you don’t need to worry about manual firmware installation.
Depending on the firmware variant, each device can function as a Zigbee coordinator, Zigbee router, or Matter-over-Thread device.
They support both ZHA and Zigbee2MQTT integrations, and can be connected via Ethernet or USB.
Home Assistant will detect them automatically after connection.
- Zigbee Coordinator – for managing a Zigbee network via ZHA or Zigbee2MQTT.
- Zigbee Router – to extend the range of an existing Zigbee network.
- Matter-over-Thread Border Router – to control your Matter devices over Thread network.
- Zigbee Hub Mode – direct control of Zigbee devices via built-in web interface (available only on TI-based models like SLZB-06, 06P7, 06P10).
You don’t need to change or configure anything when switching power sources. SLZB-06x/MRx series devices can be powered from either PoE (Power over Ethernet) or USB Type-C, and both can even be connected at the same time. Thanks to optoelectronic isolation, each power source is safely separated and protected from the other, ensuring reliable operation regardless of how you power the device.
- Via the device’s built-in web interface one-click feature;
- For Home Assistant users, directly via the official SMLIGHT SLZB integration.
No cables, no tools, no manual flashing - quick and reliable updates in seconds.
However, keep in mind that Wi-Fi, Zigbee, and Thread all operate in the 2.4 GHz band, which can lead to signal interference. While the setup is fully supported and functional, we recommend careful channel planning and proper placement to avoid wireless conflicts and ensure stable performance.
However, please note that Zigbee Hub mode is available only on devices based on TI Zigbee chips, such as SLZB-06, SLZB-06P7, and SLZB-06P10. This mode is ideal for small setups where you need basic control (e.g. switching devices, viewing sensors) without full automation. For advanced use cases, Home Assistant or Zigbee2MQTT integration is recommended.
To use this feature, you need to flash a special ESPHome-based Bluetooth Proxy firmware. This can be done directly from the built-in SLZB-OS web interface. However, please note that doing so will replace SLZB-OS, and the device will no longer function as a Zigbee or Thread adapter until SLZB-OS is flashed back - which can also be done at any time via the same web interface.
- A built-in web interface for setup, configuration, and one-click firmware updates
- Support for Zigbee Coordinator, Router, Zigbee Hub Mode, and Matter-over-Thread roles
- Integration with Home Assistant via ZHA, Zigbee2MQTT, or SMLIGHT’s native integration
- Optional features like PoE control, debug logging, and hardware diagnostics
Additionally, SMLIGHT provides an official open-source firmware for the core, which serves as a lightweight alternative to SLZB-OS. While it doesn’t offer the full feature set and polish of SLZB-OS, it’s a great starting point for customization and community contributions.
