LedFx is a network-based LED effect engine that processes real-time audio input into synchronized light shows across multiple LED strips and matrices. It runs as a Python backend with a browser-based React frontend on port 8888, controlling devices like WLED on ESP8266/ESP32 nodes via E1.31.

Use cases

• sync LED strips to music in real time
• control multiple WLED devices across a house with synchronized effects
• build an audio-reactive ambient lighting setup with ESP8266 and WS2812B strips
• run a music visualizer on Raspberry Pi driving LED matrices
• configure and visualize LED effects from a browser interface
• integrate LED lighting control into home automation via REST or WebSocket API

When to choose

• you want audio-reactive lighting effects without writing effect code yourself
• you have multiple networked LED devices (WLED, ESPixelStick) to synchronize
• you want a web UI plus REST/WebSocket APIs for programmatic control
• you're running on Windows, macOS, Linux, or a Raspberry Pi with Python 3.10+

When to avoid

• you need offline or USB-only LED control with no network devices
• you want simple static lighting scenes rather than audio-driven effects
• you need a headless embedded controller running directly on the ESP itself
• you require a non-GPL license for commercial embedding
