The SMLIGHT SLZB-MRW10U is a versatile, multi-protocol smart home gateway that supports Zigbee 3.0, Thread (Matter), and optionally Z-Wave 800 networks. The device can operate via USB, but also communicates and receives power via Ethernet and PoE (Power over Ethernet), making it highly flexible to install. It's an ideal solution for advanced DIY users and system integrators seeking a stable radio controller capable of handling multiple protocols simultaneously.

The device also supports USB over Ethernet, meaning that any connected USB device (e.g., Z-Wave stick) can be accessed remotely over the network. This enables systems like Home Assistant or other smart home platforms to manage a physically distant USB device as if it were locally connected.

Thanks to its compact size and optional DIN-rail mount accessory, it can be integrated into both home and professional electrical enclosures. It is easily configurable through a web interface and supports regular firmware updates.

Important: This device is not Z-Wave certified. Z-Wave support is available for testing purposes only.

Brand Introduction – SMLIGHT

SMLIGHT is a manufacturer of advanced, open-source-based smart home devices, known primarily for its multi-radio adapters, gateways, and hub solutions. Their products are designed to enable local (cloud-free) operation, easy integration, and user-customizable functionality. They support common automation systems such as Zigbee2MQTT, Home Assistant, ZHA, Thread/Matter, and others.

USB over Ethernet functionality allows remote access to USB devices via the local network. For example, connect a Z-Wave dongle, additional Thread stick, or any other USB device to the host USB port, and access it remotely over a TCP/IP connection. This modular approach makes it easy to expand functionality without hardware limitations.
