Shutdown scripts for OSMC

The default SSH user name for OSMC is osmc, password osmc

• Key in :
• cd /etc
• sudo nano irswitch.sh
  
• Copy and paste (use shift+ins to paste in nano) the following text into the editor window
  #!/bin/bash
  # this is the GPIO pin receiving the shut-down signal
  GPIOpin1=14
  echo "$GPIOpin1" > /sys/class/gpio/export
  echo "in" > /sys/class/gpio/gpio$GPIOpin1/direction
  while true; do
    sleep 1
    power=$(cat /sys/class/gpio/gpio$GPIOpin1/value)
    if [ $power != 0 ]; then
      sudo systemctl stop mediacenter
      echo "out" > /sys/class/gpio/gpio$GPIOpin1/direction
      echo "1" > /sys/class/gpio/gpio$GPIOpin1/value
      sleep 3
      sudo shutdown -h now
    fi
  done
• Press ctrl+x to exit, y to confirm, enter to save the file
• Key in
  sudo chmod +x irswitch.sh
• The above RemotePi Board shutdown script needs to be registered as a service, key in
  cd /etc/systemd/system
  sudo nano irswitch.service
  
• Copy and paste the following text into the editor window
  [Unit]
  Description=RemotePi Service
  After=systemd-modules-load.service
  [Service]
  Type=simple
  ExecStart=/etc/irswitch.sh
  [Install]
  WantedBy=multi-user.target
  
• Press ctrl+x to exit, y to confirm, enter to save the file
• Key in
  sudo systemctl enable irswitch.service

The following additional script enables the RemotePi Board to cut off the power, after OSMC has been shut down from the on-screen menu.

• Key in
• sudo nano /etc/shutdown.sh
• Copy and paste the following contents
• #!/bin/bash
  REBOOT_GREP=$(systemctl list-units --type=target | grep reboot)
  SHUTDOWN_GREP=$(systemctl list-units --type=target | grep shutdown)
  if [ "$SHUTDOWN_GREP" ] && [ ! "$REBOOT_GREP" ]; then
    # the condition above makes sure, that the shutdown sequence is not run on reboot 
    GPIOpin=15
    GPIOpin1=14
    echo "$GPIOpin" > /sys/class/gpio/export
    echo "out" > /sys/class/gpio/gpio$GPIOpin/direction
    echo "1" > /sys/class/gpio/gpio$GPIOpin/value
    sleep 0.125
    echo "0" > /sys/class/gpio/gpio$GPIOpin/value
    sleep 0.2
    echo "1" > /sys/class/gpio/gpio$GPIOpin/value
    sleep 0.4
    echo "0" > /sys/class/gpio/gpio$GPIOpin/value
    echo "$GPIOpin1" > /sys/class/gpio/export
    echo "out" > /sys/class/gpio/gpio$GPIOpin1/direction
    echo "1" > /sys/class/gpio/gpio$GPIOpin1/value
    sleep 4
  fi
• Press ctrl+x to exit, y to confirm, enter to save the file
• After saving the file, mark it as executable with
  sudo chmod +x /etc/shutdown.sh
• Key in
• sudo nano /etc/systemd/system/irswitch2.service
  
• Copy and paste the following text into the editor window
  [Unit]
  Description=RemotePi Board Shutdown Service
  Before=multi-user.target
  Conflicts=shutdown.target
  [Service]
  ExecStart=/bin/true
  ExecStop=/etc/shutdown.sh
  Type=oneshot
  RemainAfterExit=yes
  [Install]
  WantedBy=multi-user.target
• Press ctrl+x to exit, y to confirm, enter to save the file
• Key in
  sudo systemctl enable irswitch2.service
  
  
• Reboot one time
  
• After reboot you can use the RemotePi Board to power cycle OSMC

The above scripts have been tested and are confirmed to work with with OSMC version 2019.11-1. Although not yet tested, they most likely will work with newer versions as well.
