SLZB-MR5U

The SLZB-MR5U is a professional-grade quad-radio coordinator designed for private use, integrators, installers, and OEM partners who need stable, long-range Zigbee / Thread connectivity with Ethernet reliability and PoE power options. Based on SMLIGHT’s SLZB-OS firmware, it offers a unified web interface, local API, MQTT integration, and full OTA update support - ideal for both large-scale deployments and high-performance residential systems.

The SLZB-MRxU features a high-quality USB passthrough mode, enabling the device to function as a remote USB-radio bridge over Ethernet. This allows users to plug a USB device into the coordinator (for example, an additional Z-Wave dongle) and make it accessible to their smart home system over Ethernet (please note the limitation in the datasheet).
