SMLIGHT - Zigbee POE Ethernet USB Adapter

Introduction

The SLZB-MR3 is a next-generation Zigbee and Thread coordinator developed by SMLIGHT. It combines the Texas Instruments CC2674P10 and Silicon Labs EFR32MG24 chips, allowing full compatibility with Zigbee2MQTT, ZHA, and Matter-over-Thread.

With its USB-C and Ethernet connectivity, it integrates easily into various smart home configurations. It supports Zigbee and Thread simultaneously or in dedicated mode.

Its compact casing, PoE or USB-C power supply, and optimized antennas ensure flexible installation and efficient radio transmission.

Key functions

• Dual radio Zigbee and Thread
