How I got my Magic Mirror working on a Raspberry Pi 0 (zero)

Wieber

@SebTota Well I think there isn’t really anything wrong with your Mirror, since it shows the default page for when the Config.js is missing.
What you could do is search for the ‘config.js.sample’ file with the following command:
find -name “config.js.sample”
I haven’t used this command myself, but more info on it is found here: https://www.digitalocean.com/community/tutorials/how-to-use-find-and-locate-to-search-for-files-on-a-linux-vps

Edit: a loss in SSH connection doesn’t necessarily means that your Pi messed anything up, just like your PC can still run when your monitor disconnects. Although a connection loss could have a lot of reasons that would also mess up the Pi ofc ;)

Alright after some time I figured it out.

cd MagicMirror
cd config
sudo nano config.js
then the file should open.

This is for the noobs like me who might need that.

@SebTota What @Wieber has forgotten to mention is that the config.js.sample file is the default configuration that is included with the mirror software. The mirror software itself is looking for config.js. So the step that is missing is to copy the sample to the end file name. Once you have it copied over, this will become the file that you use to change your mirror’s behavior.

You copy the file with this command: cp ~/MagicMirror/config/config.js.sample ~/MagicMirror/config/config.js

You can then edit the config.js command as you have already discovered: nano ~/MagicMirror/config/config.js Nano is the editor, config.js is the file you are editing.

Great guide!

I have a quick question though. When my pi zero boots, it boots into a command line where i can see the modules are loading. It ends with

Ready to go! Please point your browser to: http://localhost:8080
Whoops! There was an uncaught exception...
{ [Error: listen EADDRINUSE :::8080]
  code: 'EADDRINUSE',
  errno: 'EADDRINUSE',
  syscall: 'listen',
  address: '::',
  port: 8080 }

any ideas what causes this and how it can be fixed?

@piziie I believe my pi had the same response but after a few seconds it boots into the browser and shoes the mirror and works fine. Is it the same with you?

@SebTota
unfortunately no, it remains on the terminal. When i open a browser and go to localhost:8080 it does appear to be working so i know the MM and modules load correctly.

It seems to be an issue with the midori start script?

/home/pi/startMidori.sh

#!/bin/sh
xset -dpms # disable DPMS (Energy Star) features.
xset s off # disable screen saver
xset s noblank # don’t blank the video device
matchbox-window-manager &
unclutter &
midori -e Fullscreen -a http://localhost:8080

My /home/pi/start.sh script:

#!/bin/bash
cd ~/MagicMirror
node serveronly &
sleep 45
sudo xinit /home/pi/startMidori.sh

and the last line in .bashrc

/home/pi/start.sh

another side note- on boot i get this error:

(EE) 
Fatal server error:

        If this server is no longer running, remove /tmp/.X0-lock
        and start again.

could this be the source of the error?
