The referred circuit (described in second half of the page) seems a good solution as this manager the shutdown process beside powering off. But I don’t know how the writer manages the shutdown process (if with a python code like mine one or with the power wire from RPI config.txt or other ways). In other words, if you shut down and cut current on same time (from a single button), your RPI will not have enough time to shut down correctly the OS. Please ask the tutorial creator how he manages timing for both turn-off phases: shutdown and power off

I’m learning stuff on the go, so I got some doubts, if you don’t bother helping me. I’m using this, https://othermod.com/raspberry-pi-soft-onoff-circuit/
Am I supposed to do all this circuit in the link or just that single button is enough to power on and off safely the RPI?

Thank you for your feedback. I prepared a modified version of shutdown_button code using python threading. You can get it with:
wget http://peppe8o.com/download/python/shutdown_button_2.py
then renaming in shutdown_button.py instead of old code.
This should fix CPU usage. Please, can you give me a feedback if it works for you?

Many thanks

As soon as shutdownButton.service is active the CPU is running 99.7% on python3.
