      Quick guide: which SMLIGHT device is which?

      SMLIGHT has two main families: network adapters (SLZB) that connect radios to your existing server, and standalone hubs (SMHUB) that run smart-home apps on the device itself (but also could be just a network adapter). Use the one-liners below to pick the right series fast:

      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.

      SLZB-06x/MRx series devices are smart home adapters that act as a bridge between your Zigbee or Thread devices and your smart home system, like Home Assistant. Think of them as the middleman that helps your smart lights, sensors, switches, and other devices talk to your smart home hub.
      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.
      Yes, SLZB-06Mg26U series devices are fully compatible with Home Assistant and work out of the box.
      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.
      SLZB-06x/MRx series devices can operate in several flexible modes, depending on your use case and the installed firmware. Supported modes include:
      • 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 can switch between modes through the web interface one-click action.
      Yes - SLZB-06xU/MRxU supports USB passthrough, letting you plug a USB device into it and access it over the network. It works with most common USB-to-UART chips such as CP210x, CH340/CH9102. If SLZB-06xU/MRxU is powered via PoE, the connected USB device can be powered from SLZB-06xU/MRxU’s USB port as well.
      SLZB-06x/MRx series devices support both Power over Ethernet (PoE) and USB Type-C power options. You can choose the one that fits your setup best. PoE enables a clean, single-cable installation with both data and power over Ethernet. Alternatively, if PoE is not available, simply power the device via a regular USB Type-C adapter.
      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.
      You can update both the Core chip and the Zigbee/Radio chip with just one click. There are two options:
      • 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.
      Yes, SLZB-06x/MRx series devices can work as Zigbee-to-Wi-Fi adapters. When running in Wi-Fi mode, the device connects wirelessly to your network while acting as a Zigbee coordinator (via ZHA or Zigbee2MQTT).
      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.
      Yes, you can. SLZB-06x/MRx series devices support a feature called Zigbee Hub mode, which allows direct control and monitoring of Zigbee devices through the built-in web interface - no need for Home Assistant or any external smart home server.
      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.
      Yes, SLZB-06x/MRx series devices can function as Matter-over-Thread border routers, allowing you to integrate Thread-based Matter devices into your smart home setup. This enables secure, low-power, and reliable communication over Thread.
      Yes, SLZB-06x/MRx series devices can function as Bluetooth Low Energy (BLE) proxy devices for Home Assistant. This allows them to relay BLE signals (e.g. from temperature or presence sensors) to Home Assistant over the network, extending Bluetooth coverage in your home.
      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.
      SLZB-OS is the official operating system developed by SMLIGHT for the SLZB-06x/MRx series devices. It runs on the Core SoC and provides:
      • 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
      SLZB-OS is preinstalled and tested on all devices out of the box, so you can get started immediately - no flashing required. It’s also easy to reflash later if you try other firmware like ESPHome or other Community builds and want to return to full functionality.
      Yes, you can. SLZB-06x/MRx series devices are fully compatible with community-driven open-source firmware for both the Zigbee radio (e.g. Zigbee coordinator firmware for TI or Silicon Labs chips) and the ESP32 core (e.g. ESPHome, Tasmota, or custom ESP32 apps).
      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.
