There are much nicer solutions but already to complex for me to add own commands when having basically no knowledge in php programming.
With this dashboard I can perform basic testing of my raspberry using my ipad without typing any command - just pressing buttons.
1) index.php - This file containing simple HTML
2) services.php - script to generate buttons for system commands
2) services.json - file with system commands
Below is an example for the configuration file services.json
{
"step 90 <-": "/home/pi/gpio/step.py -d 90",
"step 360 <-": "/home/pi/gpio/step.py -d 360",
"step 90 ->": "/home/pi/gpio/step.py -r -d 90",
"step 360 ->": "/home/pi/gpio/step.py -r -d 360",
"avrio ": "/home/pi/avrio/avrio.py",
"avrio 10": "/home/pi/avrio/avrio.py -r 10",
"avrio html": "/home/pi/avrio/avrio.py -w",
"show messages": "tail --lines=20 /var/log/messages",
"show systemlog": "tail --lines=20 /var/log/syslog",
"Systemzeit": "date",
"show cron log": "tail --lines=20 /home/pi/crontab.log"
}
