1. Introduction
iSG Fusion uses a new architecture with the LinknLink APP as the frontend and Termux as the backend. The hardware remains unchanged; only the software is upgraded.
Building on the original iSG stack (Home Assistant, Zigbee2MQTT, and Z-Wave JS UI), it adds LinkHub (multi-protocol super gateway), Matter Bridge, and an AI agent, along with improved version management and updates.
Existing iSG users get better stability and intelligence — a next-generation all-in-one smart home gateway for the AI era, suitable for beginners and advanced enthusiasts.
