3. HomeSpan

   2 12 1,915 9.4 C++

   HomeKit Library for the Arduino-ESP32

   

   Project mention: How I built a custom Homekit thermostat for 40€ | dev.to | 2025-03-10

   There is one library called Homespan, but this is intended for programming ESP32 in the Arduino environment. This is much easier and beginner friendly, but I wanted something more advanced and challenging :). As I said in the beginning, I wanted to get more familiar with the ESP32 environment and the arduino-esp32 project offers a lot of abstractions. That’s why I opted for the ESP-IDF framework instead.
