Quit MM with script

start-the-fire

Hi,

I’m kinda fresh to the python & bash programming but I make some progress.
I set up my MM with additional modules and an Alexa Skill via AWS services which works quite well (atm turn HDMI port on/off + start MM via npm start trigger)
This works all without any problems at the moment. I set up today the MM launch via pm2 which launches the application after every reboot. Right know I’m looking for any script (bash / python, …?) with whom I could stop the MM instance (going on I would like to activate this via an Alexa Skill trigger)

//#taken from www.cyber-omelette.com/2017/01/alexa-run-script.html
print(message)
                if message == "on":
                        os.system("~/on.sh")
                elif message == "off":
                        os.system("~/off.sh")
		elif message == "start":
			os.system("~/mm.sh")

I tried some things I came up with but I’m kind clueless how I could do this
So I’m looking for two options to quit MM - CTRL-C isn’t an option cause I’m using my rpi without any keyboard that’s why I try to set up everything with Alexa voice commands:

-> Script for deactivating MM which has been started by pm2*
-> Script for deactivation MM which hast been started manual*

//#taken from MM tutorial
//#used for pm2 & manual start with Alexa skill (if needed)
/cd ~/MagicMirror
DISPLAY=:0 npm start

If anyone have some recommendations & hints for me I would be more than pleased

Cheers Ben

Hi, maybe you can use my bash script mmhelper.sh to start/stop MagicMirror from the command line or from another script (e.q. python, nodejs).

#!/bin/bash
#
#	mmhelper.sh  start | stop | status | hdmi_on | hdmi_off| hdmi_status

function monitor_on() {
    /opt/vc/bin/tvservice --preferred > /dev/null 2>&1
    sudo chvt 6

    #  get power status --> 1 = off ,  0 = on
    power=$(/opt/vc/bin/tvservice --status |grep "TV is off"|wc -l)
    if [ $power -eq 1 ]

	cmd=start

case $cmd in
    "start") #  start MagicMirror
        pm2 start mm
        ;;

        pm2 stop all

        monitor_status

    *) echo "undefined command"
       echo "usage: $MY_NAME start|stop|status|hdmi_on|hdmi_off|hdmi_status"
esac

You also need the mm.sh script in your home directory!

pm2 flush

# start Magic Mirror system
cd ~/MagicMirror
DISPLAY=:0 npm start

Merry Christmas!
