I know there is an emergency stop button plugin, but how hard would it be to have a physical button to trigger it?
That could be a case for our plugin guru @jneilliii
I did see this once, which is similar idea
Unnecessary for me to do anything. I think the Enclosure plugin supports that if I'm not mistaken. Or possibly this one..
Configuration couldn’t be simpler, all you need is to configure listening board pin (board mode) and if the second switch terminal is connected to ground or 3.3V.
What's a "Listening board"?
I assume that would be a GPIO pin on your Raspberry Pi that it monitors.
Edit: Looking at the code, I suspect that is correct because it's using RPi.GPIO library in the plugin.
Additional warnings on their github repo...
Let me just use this thread to add some more questions
Whats "board mode"?
And according to the official spread sheets for the GPio pins it might be ok to connect a switch to
Pin 30 (Ground)
Pin 40 (GPIO021)
Is the "switch" meant to be a push button/momentary like a reset switch, or should it be a breaker?
