The Smlight SLZB-MR3U is a versatile network coordinator designed to bridge Zigbee 3.0, Thread 1.3, and Matter-over-Thread protocols within a smart home ecosystem. It stands out by featuring two separate radio SoCs—the Texas Instruments CC2674P10 and the Silicon Labs EFR32MG24—which allows both radios to operate simultaneously on different channels. This dual-radio capability is powered by an ESP32-S3 dual-core processor running at 240 MHz, ensuring stable communication across your network. To ensure a strong signal throughout your home, the device includes two external rotatable antennas with +5 dBi gain and a high transmission power of +20 dBm. You can choose between powering it via USB-C or using Power over Ethernet (PoE) through an isolated transformer, which simplifies installation by combining data and power into one cable. The WIZnet W5500 chip provides reliable 10/100 Mb Ethernet connectivity, while the SLZB-OS firmware offers a web interface for easy management, OTA updates, and native integration with Home Assistant via ZHA or Zigbee2MQTT. Housed in a ventilated ABS case measuring 160 x 24 x 28 mm and weighing only 86 g, the unit is designed for flexible placement. It can be mounted on a wall using adhesive pads or installed on a DIN rail for more structured setups. For those with existing hardware, the USB-A port supports network passthrough for CP210x or CH340 dongles, making it a useful hub for users who want to centralize their smart home controllers in one physical location.
