The SMLIGHT SLZB-MR4U is an advanced gateway that combines Zigbee and Thread in a single device. It is equipped with two separate radio chips – Texas Instruments CC2674P10 for Zigbee and Silicon Labs EFR32MG26 for Thread – ensuring high performance and stable operation.
The device can be connected via Ethernet with PoE, Wi-Fi, or USB-C, and runs on SMLIGHT’s own operating system SLZB-OS with a built-in web interface. This allows you to easily configure settings, update firmware, and monitor connected devices.
The SLZB-MR4U is compatible with Zigbee2MQTT, Home Assistant (ZHA), and other popular platforms. It offers extended range thanks to signal amplification (+20 dB) and the included external antenna (+5 dB). Optical isolation between USB and Ethernet provides enhanced safety and stability.
