Hello everyone, we're trying to use a custom arduino script (with homespan) to control the board with apple homekit.
We managed to connect the board and homekit setting fake lightbulbs properly, but the problem is that the status leds of the outputs don't turn on.
We want to control every output (and related status leds) with homekit.
We've already checked the kc868-a16 schematic, but it doesnt' explain what pins to connect for the outputs
(we already tried pins 2 and 15, as your video for the A4 showed, and pins 1, 2, 3, 4, 5, but without results).
As your video explained (this video: https://www.youtube.com/watch?v=CkCJESr2n-U) we've uploaded the arduino script with homespan installed,
the connection works, but the pins don't correspond (for the kc868-a16)

A16 board use PCF8574 for expend GPIOs, not use ESP32 pins directly.

Do you have a guide for doing this and connect the board to homekit? Or could you please explain me how to do it? Thanks in advance

But it doesn't work (i managed to connect the board to homekit, but the status leds don't turn on). What am i doing wrong? i also tried wit addresses 0x21, 0x22, 0x24 and 0x25 for inputs and outputs
