Description
A ESP32 based controller board to manage up to 16 input channels and switch relay modules connected through my adapter breakout board (see my [my other project](https://oshwlab.com/nikwest/switch16)). It also has the option to add a KNX daughter board (not tested yet). Firmware available [here](https://github.com/nikwest/shelly-homekit.git). You can make all inputs and outputs available through HomeKit.
