Usage

After installing our software (details below), you can press the button again to initiate a clean shutdown and completely cut the power to your Pi.


Software

Pimoroni has a one-line-installer to install the clean shutdown daemon. It watches the state of BCM pin 17 and, when pulled low (pressed), it initiates a clean shutdown. Last thing, just before your Pi shuts down, BCM pin 4 is pulled low to completely cut power to your Pi.


To install the software, open a terminal and type curl https://get.pimoroni.com/onoffshim | bash to run the one-line-installer.
