The Smlight SLZB-06M is a versatile Zigbee 3.0 coordinator and router designed to provide a stable foundation for your smart home network. It combines a Silicon Labs EFR32MG21 Zigbee chip with an Espressif ESP32 controller, ensuring reliable communication across your devices. To maximize signal reach, the device features a +20dB SoC output gain paired with an included +5dB rotatable antenna that can be adjusted in three dimensions for optimal coverage. Connectivity is flexible, allowing you to connect via Ethernet, Wi-Fi, or USB Type-C. You can power the unit using PoE (IEEE 802.3af) for a clean single-cable setup or through the USB port. A key technical advantage is the optoelectronic isolation between the Ethernet and USB interfaces, which lets you use both connections simultaneously without interference. The compact 160 x 22 x 24 mm housing can be easily mounted using screws or double-sided adhesive tape. This adapter is built for users of Home Assistant, Zigbee2MQTT, and ZHA who need a professional-grade bridge. It comes pre-flashed with the necessary firmware and supports remote updates for both the Zigbee and ESP32 chips via a web interface. For those who prefer manual control, a physical button and four LEDs provide immediate status feedback, while the ESP32 Autoboot feature simplifies flashing new firmware over the Type-C port.
