The firmware that makes a coordinator smart.
SLZB-OS is the onboard operating system for SMLIGHT’s SLZB Ethernet, USB and PoE coordinators. A local web dashboard, Zigbee, Thread and Matter modes, OTA updates with rollback, and secure remote access — all built in.
Run as a Zigbee coordinator for ZHA or Zigbee2MQTT, a Zigbee router, or a Matter-over-Thread border router — and switch modes in one click.
Control and monitor Zigbee devices straight from the built-in web UI — no external server or Home Assistant required.
A built-in WireGuard VPN and Dynamic DNS reach your coordinator securely from anywhere, without opening ports.
Over-the-air firmware updates that can roll back, with optional auto-update — and a web UI in 31 languages.
A whole platform on the device.
Automation API
Drive the coordinator over HTTP, Server-Sent Events and MQTT — build automations against a real API.
MQTT broker connectivity
Connect to your broker and publish device state and control topics.
Scripts & triggers
On-device automations run locally, right on the coordinator.
True multi-radio
Multi-radio models run each protocol on its own SoC — one TI, one Silicon Labs — instead of fragile multiprotocol firmware.
Flexible connectivity
Ethernet, USB, Wi-Fi and PoE — connect the way your install needs.
Access control
User authentication and access controls keep the console yours.
The essentials.

SLZB-OS is the onboard operating system for SMLIGHT’s SLZB Ethernet, USB and PoE coordinators. A local web dashboard, Zigbee, Thread and Matter modes, OTA updates with rollback, and secure remote access — all built in.
Multiprotocol (single-radio Zigbee + Thread) is deprecated — multi-radio models run each protocol on its own SoC. Feature availability varies by model tier.
