Don't forget to add the 2 lines of code to the config.txt file for the Power HAT & PiPAD:

Open terminal on Pi and type:
sudo nano /boot/config.txt
Then add the 2 lines of code:.

​

dtoverlay=gpio-poweroff,gpiopin=18,active_low=0
dtoverlay=gpio-shutdown,gpio_pin=17,active_low=1,gpio_pull=up

​

SAVE and Reboot the Pi
These settings allow a shutdown to be invoked by pulling a GPIO pin LOW (BCM17)
Once shutdown has completed, a GPIO pin is set Low (BCM18)

LibreELEC users:

​

Move into flash directory (using SSH):

​

cd /flash

 

By default /flash is mounted read-only so you need to type the following: -

​

mount -o remount,rw /flash

​

now we can edit the config file by typing

​

nano config.txt

 

Enter the 2 lines at the bottom of the file:

​

dtoverlay=gpio-poweroff,gpiopin=18,active_low=0dtoverlay=gpio-shutdown,gpio_pin=17,active_low=1,gpio_pull=up

​

Press Ctrl+x to exit and save by pressing RETURN/ENTER.

​

Next we need to setup a KEYMAP as the following:

​

Move to the relevant folder…

​

cd /storage/.kodi/userdata/keymaps

 

Create the .xml file…

​

nano keyboard.xml

 

Paste the following code into the file:

​

<keymap>

<global>

<keyboard>

<power>shutdown</power>

</keyboard>

</global>

</keymap>

​

Press Ctrl+x to exit and save by pressing RETURN/ENTER.

​

Finally reboot your system and the SHUTDOWN and STARTUP operation is managed by the power button.
