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). It also has the option to add a KNX daughter board (not tested yet).

Firmware available here. You can make all inputs and outputs available through HomeKit.
