Ping script / Alive check

[timmpo]

I have trouble with system alive checker so i wrote a little shell script...

A script for alive system check that post json to Domoticz dummy switch. No need for edit crontab

Make some dummy switch in Domoticz
Edit the settings in the script
Save script file in /home/pi/domoticz/scripts
Give the script ritghs to execute (sudo chmod 777 filename) or (sudo chmod -R 777 dir name ) or (sudo chmod u+x filename)
Test the script in terminal
Make the script to run at startup: https://www.dexterindustries.com/howto/ ... t-startup/

Code: Select all
