PyLoxone is a Home Assistant integration that enables communication with Loxone Miniserver systems. It allows Home Assistant to discover, monitor, and control Loxone devices (lights, switches, sensors, climate systems, etc.) through both HTTP API and WebSocket connections. The architecture separates Home Assistant-specific logic from the Loxone communication protocol via a dedicated pyloxone_api library. Key features include automatic token-based authentication with refresh capabilities, real-time state updates via WebSocket, entity creation across multiple Home Assistant platforms (sensor, binary_sensor, switch, cover, climate, media_player, etc.), and services for sending direct commands to Loxone devices. The integration handles connection lifecycle management, device discovery, and provides diagnostics and system health information.
