SMLIGHT - USB Ethernet POE Adapter Zigbee and Thread CC2674P10 + EFR32MG26

Introduction

The SMLIGHT SLZB-MR4 is a next-generation multi-radio USB Ethernet PoE adapter designed to offer maximum compatibility and total flexibility in managing smart home networks. Equipped with the powerful Texas Instruments CC2674P10 and Silicon Labs EFR32MG26 chipsets, it combines Zigbee 3.0 and Thread (Matter-over-Thread) in a single device. This solution allows for the construction of an open, scalable smart home environment independent of proprietary solutions, while ensuring exceptional stability and range.

Thanks to its advanced connectivity (USB-C, Ethernet, and PoE 48V), high-performance antennas, intuitive web interface, and multiple configuration options, the SLZB-MR4 meets the needs of smart home enthusiasts and professional integrators alike. Pre-flashed and ready to use, it is compatible with Zigbee2MQTT and ZHA, and can be used in coordinator or router mode.
