KC868-A8 and PCF8574 Interrupt pin

[powerup]

YES, PCF8574's interrupt pin not used by ESP32.

Thank you. is there any plan to do this in future?

It's a bit easier and I think more reliable than scanning the bus continously to get input.

I have ordered the A16 board which arrived today. I will take a look at that one as well.

Thank you.
