FluxFace is an ESP32-based smart LED display that visualizes electricity price levels on an RGBW LED strip. It connects to Wi‑Fi, fetches pricing data, keeps time in sync, and lights the strip according to configured thresholds so you can quickly see when electricity is cheap or expensive at a glance.
This project is designed for a GitHub audience: it is small, self-contained, and aimed at makers who want a practical embedded project built on ESP-IDF and a browser-based configuration interface.
Hardware
The firmware is built around an ESP32/ESP32-S3 class device and a 5V-powered SK6812-compatible LED strip.

5V power supply sized for the strip
Data wire connected to GPIO 16
Common ground between the controller and the LED strip
