Quit MM with script

  • S

    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*
      0_1514065764454_37b4104c-9236-4f20-8271-c8b78bfa70fb-image.png

    • -> 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

    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!
