KC868-A8M and PCF857x error

[lonammcrae]

I just got the KC868-A8M v1.1 board and ran into some issues right from the start. Inputs and outputs don’t seem to respond, even though I2C scanner detects the PCF modules at 0x22 and 0x24. The debug logs show read/write errors, and LEDs don’t light when outputs are triggered. It looks like something with the PCF initialization isn’t working correctly, and I’m still trying to figure it out.

do you use KCS v2 firmware or ESPHome yaml?
if use by KCS firmware, you need to set IFTTT for INPUT toggle OUTPUT.
