SMLIGHT SLZB-06U – Zigbee, Ethernet, PoE, USB, Wi-Fi adapter (CC2652P)

The SMLIGHT SLZB-06U is a modular, multi-protocol LAN + USB gateway that combines central control for both Zigbee 3.0 and Thread (Matter over Thread) networks in a single device. Its high-gain external antenna and next-generation radio chip (TI CC2652P) ensure a stable, long-range mesh network. With Ethernet (PoE), Wi-Fi, and USB-C connectivity options, it offers flexible installation possibilities.

The “U” edition is an enhanced version of the SLZB-06: it introduces hardware flow control for the radio SoC, software-controllable RJ45 LEDs, and a USB mode where the radio appears as a separate USB-serial device. USB passthrough (USB-over-IP) is also supported, allowing USB radios (e.g. ZWA-2) to be accessed over the network.

It's an ideal solution for future-proof, cloud-independent smart home installations based on Home Assistant, Zigbee2MQTT, and OpenThread, where flexible integration with the Matter ecosystem is essential.

About the SMLIGHT Brand

SMLIGHT develops multi-protocol smart home gateways and LAN/PoE adapters for DIY and professional users. The brand focuses on providing local control and compatibility with open ecosystems (Home Assistant, Zigbee2MQTT, OpenThread, Matter).

Key Product Features

• Multi-protocol gateway: Zigbee 3.0 coordinator + Thread border router in one, with Matter-over-Thread support.
• “U” edition extra features: HW flow control for both radios; software-controlled RJ45 LEDs; in USB mode, two separate USB-serial ports (for CC and EFR radios).
• USB passthrough (USB-over-IP): Use USB devices (e.g. Z-Wave sticks) over Ethernet as remote serial ports.
• Robust radio hardware: CC2652P, +20 dBm TX power, external SMA antenna for extended range.
• Flexible connectivity: Ethernet (PoE 48 V), Wi-Fi, USB-C power; compact, ventilated, mountable enclosure.
• SLZB-OS firmware: web interface, VPN support, multilingual UI, zHub mode, scripting, OTA updates.

Smart Home Protocols & Compatibility

• Supported protocols: Zigbee 3.0 (Zigbee2MQTT, ZHA), Thread (Matter over Thread).
• Simultaneous operation: Zigbee and Thread can run in parallel or switchable mode for multi-radio environments.
• Compatibility: Works with Home Assistant (ZHA, Zigbee2MQTT, OpenThread Border Router) and integrates with Matter platforms via Thread.
• Network access: Ethernet (PoE), Wi-Fi; USB passthrough for remote USB-serial use.

Smart Features

• USB-over-IP: Share USB radios (e.g. Z-Wave) over the network as if locally connected.
• Web interface: Manage radios, switch modes, configure network settings, control LEDs, update firmware.
• Advanced diagnostics: Independent status LEDs per radio; HW flow control ensures stable frame transmission (prevents buffer overflow—CTS/RTS signals pause transmission if the receiver can't keep up, avoiding data loss in Zigbee/Thread packets).
• USB dual CDC: When connected to a PC, two USB-serial ports appear—one for each radio (CC and EFR).

Technical Specifications

• Model: SLZB-06U
• Radio SoCs: Texas Instruments CC2652P (+20 dBm TX, 144 kB + 8 kB RAM, 704 kB Flash)
• Supported stacks: TI Z-Stack (CC2652P)
• Protocols: Zigbee 3.0; Thread (Matter-over-Thread); parallel/switch mode for multiple radios
• Connections: Ethernet (RJ45), PoE 48 V support; Wi-Fi; USB-C for data and power; USB-C passthrough
• USB functions: USB passthrough (USB-over-IP); dual USB-serial ports when connected to PC (CC & EFR)
• Firmware: SLZB-OS (v2.9.7 or newer); web-based updates; VPN, 20+ languages, scripting, zHub mode, OTA
• LEDs: independent radio status LEDs; RJ45 LEDs can be turned on/off (U version)
• Power consumption: low power use, ≤ 1.5 W (with both radios active)
• Power input: PoE 48 V or USB-C 5 V DC (only one power source should be used at a time)
• Enclosure: compact, ventilated ABS housing; supports DIN-rail and wall mounting (3D models available)
• Peripherals: multi-button (mode switch, reset); dedicated LEDs: 2× Core SoC, 2× CC2652P
• Note: USB passthrough and simultaneous Zigbee/Thread operation depend on SLZB-OS settings; do not use both power sources at once.

Recommended Use

This product is highly recommended for anyone looking to easily and efficiently integrate Zigbee devices into a smart home system. The SLZB-06U ensures high reliability, remote management capabilities, and strong, wide-range connectivity.
