SMLIGHT SLZB-MR1U - Modular Zigbee / Thread / USB Coordinator Over Ethernet

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, adding a unique feature: USB device passthrough over Ethernet. This modular device allows you to connect and access remote USB devices, such as Z-Wave sticks or custom modules, via the local network, providing unprecedented flexibility for advanced smart home installations. Connect your Z-Wave dongle to the SLZB-MR1U’s USB port and control today’s most popular wireless protocols.
