If you’re running “headless (no keyboard or display)” then adding some kind of “off” switch or button will let you shutdown without unplugging.
How do I restart and shutdown my Raspberry Pi?
We can reboot the Pi by switching from the halt ( -h ) to reboot ( -r ) command. The following example loads another Python script on startup. The Raspberry Pi will safely reboot or shutdown with the commands depending on how long we press on the button connected to GPIO17.

How do I power my Raspberry Pi 4 from GPIO pins?
On the Pi 4B there is no poly fuse, pins 2 and 4 are wired directly to the power pin on the USB C power jack. It works both ways. Power the Pi via the USB C and your hat will get its +5V via pins 2 and 4. And conversely, a hat can power the Pi by supplying +5V to pin 2 or 4.
What is a GPIO interrupt?
GPIO interrupt handling is inherently a two-stage process. The interrupt from the general-purpose I/O (GPIO) controller, which causes the GPIO framework extension (GpioClx) interrupt service routine (ISR) to run, is called the primary interrupt.
