  1.1 Overview

  SLZB-OS is the official firmware platform developed by SMLIGHT for its line of Zigbee and multi-radio Ethernet/USB/PoE adapters. It provides a web-based management interface that allows you to configure, monitor, and control your device from any browser on your local network — and, if desired, from remote locations via VPN or DDNS.

  The system is designed for stability, performance, and seamless integration with modern smart home ecosystems such as Zigbee2MQTT, Home Assistant (ZHA), and other MQTT-capable platforms.
