In order to use a GPIO connected button as a power off switch I have set a pullup for pin 23 in a dtb overlay (following http://blog.gegg.us/2017/01/setting-up-a-gpio-button-keyboard-on-a-raspberry-pi/ and https://github.com/fivdi/onoff/wiki/Enabling-Pullup-and-Pulldown-Resistors-on-The-Raspberry-Pi).
Now in python, when I
import gpiozero the pin seems to be "reset" and the pullup drops. I don't intend to use pin 23 at all in python. How can I tell gpiozero to leave it alone? Actually i would have assumed the individual pins to only be configured when first used with gpiozero.
