tfmalt / esp32-led-bookshelf

First attempts at controlling led lights with an esp32

LED Bookshelf Controller

A programmable LED controller with full Home Assistant integration.

Goals

• Brush the dust of my 20 year old C/C++ knowledge
• Familiarise myself with the ESP32
• Do proof of concept for a modern cloud centric IoT architecture
• Create a really cool bookshelf

Functionality

• Communicates with MQTT over TLS
• Full MQTT controll interface
• Implemenents the MQTT Light json interface for talking to a home assistant server
• Controls WS2812B or SK9822 ledstrips to create a beautiful bookshelf
• Uses the SPIFFS file system library to separate configuration from controller logic.
• Supports OTA firmware updates
• Audio input with FFT frequency analysis to create audio responsive light displays.

TODO

• Implement custom UI and options beyond what the deafult home assistant interface offers.
