Power button + Status LED

HesiRe

I'm trying to configure a power button and a status LED adding this lines to /boot/config.txt:

# Enable power button

dtoverlay=gpio-shutdown,gpio_pin=3

# Enable LED/power status indicator

enable_uart=1

In Rapsbian and Octoprint it works well, but in Repetier-Server I only can have status LED working. How can I enable pushbutton with this overlay?

Our image is also based on Raspbian, so same solution should work I guess. We are already based on buster and there might be a package missing you need. Never did this with overlays so no idea. 
We have gpio support for our lua language in side server and you can do the shutdown there as well, see

last example is a shutdown button.

This overlays worked on Jessie and also on Buster with RPi 3. I don’t know what is missing in RPi repetier-server image.

Adding the special dtoverlay to config.txt will allow a safe shutdown without the need for any additional code running. It’s one easy option and also adds power on feature.

I just added this line:

dtoverlay=gpio-shutdown,gpio_pin=3

after

enable_uart=1

Now it works!!!

This way it's better than adding code. Adds power on and power off features and is lighter because you need no code.

If order does matter it sounds like enable_uart=1 uses the pin as well also pin 3 is I2C pin.

Your solution is also nice because it can also repower the pi according to

I’m using this solution with pushbutton and LED integrated and it work very well in my Raspberry Pi with Repetier-Server.
