Hi,
as in the docu is written

Shutdown (you need to hold button for 2 secs for shutdown) GPIO3 (PIN5) and GND
!!! IMPORTANT Only when using the above listed pins for wiring your shutdown pin you will be able to power-up the Raspberry PI from firmware halt. !!!

As Pin 5 is used for I2C - bad.

Changing the shutdown pin in the /boot/config.txt didn't work - any idea?

dtoverlay=gpio-shutdown,gpio_pin=40,active_low=1,gpio_pull=up

#Thanks
