Multiradio-Gateway für Zigbee 3.0 / Thread (Matter), LAN/PoE und USB-Passthrough

The SLZB-MR1U is SMLIGHT’s new, advanced multi-radio coordinator that combines the CC2652P7 and EFR32MG21 chips in a single device, providing full support for both Zigbee and Thread networks.

Developed for seamless integration with Zigbee2MQTT and ZHA, the SLZB-MR1U offers exceptional flexibility for your smart home setup.

In addition, the device features an integrated USB passthrough function, allowing USB radio devices such as Z-Wave sticks, additional Zigbee coordinators or UART modules to be used over the network as if they were connected locally.

Whether you are building a pure Zigbee network, experimenting with Matter over Thread or want the freedom to switch between different ecosystems, this multi-radio coordinator brings everything together in one powerful solution.

Multiradio Connectivity kombiniert Zigbee und Thread in einem Gerät und ist ideal für Matter und flexible Integrationen.

Dual Radio Architecture mit CC2652P7 (Zigbee) und EFR32MG21 (Thread) ermöglicht parallelen Betrieb bei korrekter Kanalwahl.

Versatile Connectivity unterstützt Ethernet (LAN) mit PoE (IEEE 802.3af), USB-C und Wi-Fi und eignet sich perfekt für flexible Installationen sowie stabile Strom- und Datenversorgung über das Netzwerk.

Smart Home Optimization macht das Gerät ideal für hybride Setups mit Zigbee- und Thread-Geräten in einem System.

Stable 2.4 GHz Performance sorgt für zuverlässige Funktion bei richtig zugewiesenen Kanälen (Koexistenz).

Energy-Efficient, Compact Design ist lüfterlos, platzsparend und effizient für den Dauerbetrieb.

USB Plug & Play ermöglicht einfachen Anschluss an Home Assistant Geräte oder Server via USB.

Firmware Updates werden über USB und OTA (plattformabhängig) unterstützt.

Compact Size von nur 22 mm Breite ist ideal für enge Einbauorte.

USB Passthrough over Ethernet (USB-over-IP)

SLZB-MR1U allows you to access USB devices over the network as if they were connected locally.

Supported USB devices: Z-Wave sticks, additional Zigbee coordinators, UART modules, and most modern USB smart-home radio sticks

Compatible chipsets: CP210x, PL2303, CH340/CH341, CH9102

Home Assistant example: tcp://192.168.1.100:8638

Where the SLZB-MR1U design originates:

Zigbee and Thread are among the most important smart home protocols today. Many systems rely on both technologies at the same time – often requiring separate devices (Zigbee coordinator + Thread border router).

The MR1U provides a compact, open and flexible solution that combines both protocols in a single device, without vendor lock-in and fully compatible with open ecosystems such as Home Assistant, ZHA and Zigbee2MQTT.

The MR1U uses the CC2652P7 radio chip for Zigbee and Matter-over-Thread, supported by a powerful ESP32 controller that handles networking, USB and PoE. With SLZB-OS you benefit from features such as autodiscovery, OTA updates, VPN support, scripting and easy mode switching.

For PoE usage, a compatible PoE power supply and a suitable network cable are required (not included in the package).

To use PoE, a compatible PoE power supply and two suitable network cables are required (not included). One cable connects the PoE power supply to the network (e.g. router or switch), the second cable runs from the power supply to the device, delivering both data and power. Suitable network cables are available in our shop.
