Interesting RPI pushbutton on/off switch
Posted: Thursday 26 September 2024 15:17
In fact this post has nothing to do with Domoticz and at the same time it has.
There are occasions that I try to jeopardize my sytem by experimenting with Domoticz.
Sometimes the system 'hangs' and I can see the WiFi leds flicker and the green led flickering as well.
That means there is still life in the system, however I am not able to get Domoticz pages in the browser nor do I have SSH access.
Up till today I had to shut off the system by switching off power.
That does harm the linux system sometimes and can lead to a reinstall of everything in case you didn't backup.
The button procedure is described in this youtube video showing an undocumented feature of dtoverlay.
This means you don't have to write a python script to shut off the system.
The push button both closes the system and starts it up as well.
