- The installation process should create a systemctl service to start/stop the process instead of using crontab.

I did the following:

Copied /home/pi/x728/x728v2-asd.py to /usr/local/bin: sudo cp /home/pi/x728/x728v2-asd.py /usr/local/bin

Then created a systemctl service file to start the script:

sudo vi /lib/systemd/system/x728-shutdown.service

Contents of the file:

[Unit] Description=Geekworm x728 Shutdown Service After=network.target

[Service] Type=simple StandardOutput=null WorkingDirectory=/usr/local/bin User=root Restart=always RestartSec=3 ExecStart=/usr/bin/python3 /usr/local/bin/x728v2-asd.py ExecReload=/bin/kill -2 $MAINPID KillMode=process

[Install] WantedBy=multi-user.target

Then I reloaded systemctl to read the new service file:

sudo systemctl daemon-reload

Enable the service:

sudo systemctl enable x728-shutdown.service

Started the service:

sudo systemctl start x728-shutdown.service

Display the status:

sudo systemctl status x728-shutdown.service

MUCH better than adding to crontab!
