Execute bash command/Turn off GPIO (LED) from mirror

BKeyport

I’m looking for a quick and dirty way to turn off an LED once the mirror fully loads - basically getting around the slowness in Electron from all the random little errors on startup and waiting for systems that will never start.

I don’t care if it’s a quick module I build myself, or something else.

I’m assuming it can be done with all the abilities to read system info etc - just not sure how to do it myself.

Thanks!

tip: try to use gpiozero ;)

@bugsounet I actually have the bash command I need to run. Just the part of interfacing through the Mirror is what I need help with.

ah sorry, so exec your code it when all modules are started.

with ALL_MODULES_STARTED incoming system notification, you can send a notification to node_helper for exec your bash script

For execute it in node_helper, you can use exec command of child_process library

See:

system notification: about all system notification
sendSocketNotification for send a notification to node_helper
socketNotificationReceived for read notification in node_helper

@BKeyport
MMM-NotificationTrigger for that purpose.

@wishmaster270 @MMRIZE I figured one of you wizards already figured it out. I had forgotten about the all modules notification, and then I would have realized all the pieces are already there.

FWIW, MMM-Notification-To-Command is exactly what I was aiming for.

@BKeyport you might want to look at raspberry pi 5 I use it to turn LEDs on and off
I also use believers are not Dragon NaturallySpeaking which is pretty cool because I can write a letter and also turn LEDs on and off just by voice

@Ray pinctrl 17 op dl does the work behind the scenes, I just needed a way to call it from the mirror, which I got with MMM-Notification-to-command.
