The SMLIGHT SLZB-MR1U adapter is a modern, multi-protocol LAN adapter that allows central control of Zigbee, Thread, and Z-Wave systems (via USB dongle) from a single device connected to Ethernet. It features built-in USB passthrough functionality over TCP/IP, allowing a connected USB dongle (e.g., Z-Wave) to be exposed on the network as a remote serial port, as if it were connected directly to your server.

The MR1U version offers Ethernet with PoE support, Wi-Fi/Bluetooth, USB-C, and USB-A for expansion. It uses the TI CC2652P radio chip as a Zigbee coordinator and the EFR32MG21 as a Thread Border Router, while network management is handled via an ESP32. It is a suitable choice for Home Assistant, Zigbee2MQTT, and advanced installations.

Main Features:

• Multi-protocol operation: Zigbee 3.0 (CC2652P) and Thread Border Router (EFR32MG21); additional radios can be connected via USB host.
• USB passthrough over Ethernet: exposes USB radios (e.g., Z-Wave stick) over TCP/IP for remote access.
• USB-UART compatibility: support for CP210x, PL2303, CH340/CH341, CH9102.
• Flexible connectivity: LAN + PoE for stable power/network, Wi-Fi for flexible placement, USB-C as alternative power, USB-A host for expansion.
• Plug&Play SLZB-OS: built-in web interface for easy configuration and setup.
• Platform compatibility: Home Assistant (Zigbee: ZHA / Zigbee2MQTT), OpenThread, Z-Wave JS (via USB passthrough).

Technical Specifications:

• Radio chips: Texas Instruments CC2652P7 and Silicon Labs EFR32MG21, supporting Zigbee 3.0 and Thread.
• Connectivity: USB-C for data and power, Ethernet connection, USB-C passthrough.
• Power supply: Capable of powering via PoE and USB-C, low power consumption.
