I'm looking for a pir integration in home assistant and I have some difficulties to find documentation online.

I bought a M5 atom echo esp32-pico and connected a PIR Motion Sensor (AS312) on the hy2.0-4p expansion port

I see that the hy2.0-4p expansion port pinout is G;5V;g26;g32 but it looks like it isn't related to gpio26 nor gpio32.
The standard example in home assistant refers to gpio39 for the button and it works
If I define GPIO26 or 32 for the PIR it doesn't

could you send me some documentation about it or give me some advice/support?

Thanks,
L.
