BINGO Got it to work. Not sure if others had a problem with this or its something new. but here it is.

However, there is a bug on the generated startup script that prevents PM2 from automatically run at startup. You will need to edit /etc/init.d/pm2-init.sh and

replace: export PM2_HOME=“/root/.pm2”
with: export PM2_HOME=“/home/pi/.pm2”

Got this from here: https://bekti.io/automatically-start-a-node-js-application-on-raspberry-pi/

Ok so i started doing some more digging. First i have a question PM2 does it actually load MM from a full reboot? meaning power off to RPI and a full start.

The reason i ask is because
When i open terminal in RPI and type npm start from MM directory it loads MM without any problems. Then i hit Ctrl Q it quits.
Then i do PM2 list and gives me 0 apps running.
Then I do pm2 start mm.sh again loads MM without a problem. Then i hit Ctrl Q it exits MM for about 10sec and then loads it back. During the 10sec I did pm2 list again and it said MM is running.

So I dont think PM2 is actually loading MM from a full reboot.

Ok so i also tryed to do pm2 lists and there is nothing in the list. Does that mean anything?

Well Just reinstalled PM2 and still nothing. Using this guide not sure if everything is correct on that. https://github.com/MichMich/MagicMirror/wiki/Auto-Starting-MagicMirror

Is there a way to see if PM2 is even trying to load MM on start up. Or maybe something wrong with this command:
cd ~/MagicMirror
DISPLAY=:0 npm start

Yes it did I will try to uninstall and install it back. Thanks B.

Noobs is the PI noobs interface almost like a windows (https://www.raspberrypi.org/downloads/noobs/). From there i can select terminal and then i get the pi@raspMirror:~ $. PM2 seems to work and is linked because when i type pm2 start mm.sh it does load MM. So I assume that PM2 is linked with MM since i can load it through PM2. So for some reason PM2 is just not loading it on start up.

Ok so i did the config option that you said and still no luck. Is there a way to uninstall PM2 so i can try to reload it again?

Ok so i figured out how to exit out of MM. But its still not starting after reboot. Can anyone help me or is there anything i can try to do.

Ok so i got everything set up installed pm2. I am able to start pm2 and also MM “pm2 start mm.sh” load fine but when i reboot the raspberry pi 3 it doesn’t load in to MM it loads in to NOOB. Not sure what i did wrong.

The one thing i had a problem with is when starting MM through pm2 your supposed to exit it and save settings. Problem was i didnt know how to exit so i rebooted rpi. So my question here is also how do you exit MM? :(

Hi I was wondering if some one can give me a hand with this Module.
So i am trying to set this up and have a dum question. How do you “Run getToken.sh”

How would i put that in to the terminal?

I Know i would direct it to the MMM-Nest folder and then from there would i put “npm start getToken.sh”

Any way you can point me to the module?
I did order rpi 3 and the camera for it. I am guessing the motion will have to work through that camera.
