- ## **1. About SLZB-OS**
    
    ### **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.

    2. Determine its IP address using your router’s DHCP client list or a network scanning tool.
    3. Open a web browser and enter the device’s IP address in the format:
        
        <div class="contain-inline-size rounded-2xl relative bg-token-sidebar-surface-primary"><div class="sticky top-9"><div class="absolute end-0 bottom-0 flex h-9 items-center pe-2"><div class="bg-token-bg-elevated-secondary text-token-text-secondary flex items-center gap-4 rounded-sm px-2 font-sans text-xs">  
        </div></div></div><div class="overflow-y-auto p-4" dir="ltr">`http:<span class="hljs-comment">//<device-ip-address></span>`</div></div>
