Introduction

The SMLIGHT SLZB-MR1U is a next-generation smart LAN adapter designed for connected homes. It builds on the solid foundation of the SLZB-MR1 by adding a unique feature: USB device passthrough via Ethernet. This modular device allows you to connect and access remote USB devices, such as Z-Wave keys or custom modules, via the local network, offering unprecedented flexibility for advanced smart home installations.

Key Features

• Zigbee 3.0 support via the Texas Instruments CC2652P chipset, compatible with Zigbee2MQTT and ZHA.
• Thread Border Router functionality thanks to the Silicon Labs EFR32MG21 chipset, compatible with OpenThread.
• USB passthrough over Ethernet allowing connection and access to remote USB devices via TCP/IP.
• Integrated Wi-Fi and Bluetooth connectivity via an ESP32 module.
• Modular architecture allowing connection of any USB device via a port or USB hub.
• Power via LAN with PoE (Power over Ethernet) or via USB-C for flexible installation.
• Compatibility with smart home platforms such as Zigbee2MQTT, Home Assistant, OpenThread, and Z-Wave JS (via a USB stick).
• Pre-installed SLZB-OS operating system, with firmware update via a web interface.
