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

Doubleve

don’t work for me, cannot connect to destination :-(

when i do

DISPLAY=:0 npm start

npm ERR! path /home/pi/package.json
npm ERR! code ENOENT
npm ERR! errno -2
npm ERR! syscall open
npm ERR! enoent ENOENT: no such file or directory, open ‘/home/pi/package.json’

Doubleve

why he’s looking for /home/pi/package.json then it is /home/pi/MagicMirror/package.json ?

This is my log

@Doubleve
In which directory did you execute npm start
? I would assume you would first go to your MagicMirror directory (cd /home/pi/MagicMirror ). This would also explain the problem with the missing package.json file.

However, I’m not sure if npm start works at all in combination with the serveronly mode (needed for the Pi Zero). For starting, I use the method described in the first post of this thread in the section “Setting up boot scripts”.

I can acccess my MM from remote, however still didn’t get it to show in the Midori browser :-/

Doubleve

as you said I was not in the right record.
I had an error with the libnss3 library. Now more error

DISPLAY =: 0 npm start

magicmirror@2.1.3 start / home / pi / MagicMirror
sh run-start.sh

pi @ raspberrypi ~ / MagicMirror $ npm run config: check

magicmirror@2.1.3 config: check / home / pi / MagicMirror
node tests / configs / check_config.js

Checking file … /home/pi/MagicMirror/config/config.js
Your configuration file not containt syntax error :)

but it still does not work with midori

What does npm start do in /MagicMirror

bhepler

@noorm91 npm start is the command to start the Magic Mirror application and display the interface on the screen.

I can’t seem to start MM with npm start, tried through SSH and directly on rpi with keyboard.

Thats what I expected for the Pi Zero. Did you try the method described in the first post of this thread in the section “Setting up boot scripts”?

Doubleve

I took everything back with the first post everything works !!!

Hawking

@Doubleve
Can you tell me which Linux distribution (lsb_release -a), node version ( node -v ) and version of MM you are using?

Hi guys, I saw someone asked before, isn’t there anyone who has a working image for MM2 on a Pi Zero. I tried a lot of things before, cant get it to work. Now, I don’t have a lot of time to experiment with it, school and work are killing me. My mirror is lying around, unused. Please help me out here,
Thanks!!

noorm91

@delusional112
Here is an image, it has a couple of errors that needs fixing but the magicmirror starts at least.
If you have any solutions please keep us informed…this image is made by Sebtota.

Any clue on what is trying to start and not functioning alright here?

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?

This usually means that you already have a process trying to serve up web pages on port 8080. In my experience, this happens when you do not terminate your previous attempt to run the MM process and start up another one. The new one also tries to serve up pages on port 8080 and you get that error.

You can use ps ax | grep node to see if node is running when you attempt to start your mirror. If it is, node is already serving up pages, so you will want to stop whatever process is running first. Alternately, if you are running a web server on port 8080 already, you can switch the port of the MM process in the config.js file.

So did anyone get MM2 on a Pi Zero W with Raspian Stretch lite running?
Or is it better to stay with Jessie?

Hawking

@MarWind
I still didn’t get it to work using Midori in combination with Raspian Stretch Lite.
On this distribution, I could only get it to work using Epiphany or Chromium. However, their performance is much slower than Midori (which worked fine in Jessie Lite). I can’t tell if this is due to some general changes in Stretch or in the newer versions of Midori.

noorm91

How did you install Chromium on rpi 0 ?

MarWind

@hawking, thanks for your answer!

I’ll do some more testing:

*So my main issue will be now the update of mm2 :-(
I’m running an working image on the pi zero w with npm 2.14 and node 4.2.1 for month’s now.
But after updating MM2 last week with git pull && npm install it’s broken :-(*

Hawking

@noorm91
I simply did

sudo apt-get install chromium-browser

and the start is by

chromium-browser --incognito --kiosk http://localhost:8080

I don’t know if this is a new possibility in Stretch light or is also possible in Jessie Lite (I know that there were some issues in the past). However, as I said, the performance is slow and not stable (I see that the free amount of memory gets low and the system freezes every few hours). Therefore I would prefer to use still Midori, whoch worked fine for me in Jessie. However, using Midori with Stretch I simply get a black screen. I don’t know if this is due to an error in my installation, due to changes from Jessie to Stretch, due to changes in the Midori browser, due to changes in MM (I tried to install an older version, which didn’t help) or yet another reason.
