KC868-A6 Digital input IRQ

[Libramale]

@Admin

Thanks for the feedback, I did see the thread linked before posting the question.

So. just to clarify: What you are saying is that the nINT pin on the PCF8574 has not been connected to any GPIO and that I will have to strap wire it to an ESP32 GPIO.

Any chance you can share a photo showing where the PCF85743 nINT pin/pad can be intercepted and where it can be connected to an unused and suitable ESP32 GPIO.
Being primarily a FW/SW guy I would prefer not to mess around unguided on a PCB.

Thanks
