gpiozero VS raspberry-pi-safe-off-switch

It was a bit tricky to get CPU temperature of a host machine (Raspberry Pi) from within the running docker container. This Issue on GitHub has helped me :

No. The pi 4 is not a microcontroller. However, I would recommend gpiozero for a regular pi4

I run it in K3s on Raspberry Pi OS. The service is built on gpiozero so should work on other devices. It is a very helpful building block in my DIY home automation system. It's a general purpose connector so it can be configured for many different uses. At present I use it to:

Gpiozero is already installed in the current Raspberry Pi OS - if not, just run python3 -m pip gpiozero. The source code files can be accessed on Github. The official documentation on readthedocs.io provides rich information and plenty example code.

The code we will write will be in Python. Let's start with just getting the button to register. We will be using the gpiozero library to do this:

I'm very new to all things pi, or really electronics in general, but I'm enjoying the learning process so far. I'm trying to add a power button to my Pi4, using the GPIO zero library, but can't quite get the last step to work. I've set up my button on the GPIO3 pin and the ground next to it. For now I'm just trying to get the simple_shutdown working, so after changing that script from GPIO21 to 3 I've saved it, changed it's permissions using 'chmod a+x', then added the following into /etc/rc.local: ````echo '~pi/shutdown-press-simple.py &' >> /etc/rc.local

You need a power switch and a reset switch. See here for instructions https://github.com/TonyLHansen/raspberry-pi-safe-off-switch/
