About LED Controller

LED Controller started as a personal project to build the perfect aquarium lighting system. Frustrated by expensive, closed-source controllers with clunky interfaces, we designed an open, ESP32-S3-based controller that anyone can configure from a web browser.

What It Does

• 100% local, no cloud required. The controller runs its own web server over WiFi. No remote servers, no accounts, no internet dependency. Your lighting keeps working even if your internet goes down.
• 8 independent constant-current channels, designed for Mean Well NLDD-H or LDD-H drivers
• 24-hour scene scheduling with smooth ramp transitions (linear, ease-in, ease-out, ease-in-out)
• Real-time weather simulation: cloud dimming, rain flicker, and lightning flashes driven by live weather data
• Built-in React web UI served directly from the ESP32 over WiFi. No app install required
• WebSocket real-time updates for instant status feedback and control
• Favorites & presets: save up to 16 lighting profiles and recall them instantly
• Rotary encoder support for physical hands-on brightness control
• OTA firmware updates: update your controller over WiFi
