Raspberry Pi Zero W for Magic Mirror

[davidgagne]

@sdetweil said in Raspberry Pi Zero 2 W for Magic Mirror:

flash the sd card… its a pi02W, a 3 in pi0 form factor

I’m sorry but I don’t understand what this means. Which PiOS should I flash? I have been trying with the Legacy, 32-bit.

(If it makes a difference, I actually have a Raspberry Pi Zero W Rev 1.1. I don’t think it’s a 2.)

Thank you!

[sdetweil]

@davidgagne ok, if it IS a pi0W, then 32 bit legacy image

flash sd card, boot to the desktop, use terminal window or ssh

then my install script.

they have removed the chromium browser, for armv6l, so you will have to use firefox or one of the others… midori or surf

so YOU MUST use the environment variable in
~/MagicMirror/installers/mm.sh to set the browser to use ( all have to be installed manually)

[davidgagne]

@sdetweil Okay. I’m doing this right now.

1. Flashed card with Legacy 32-bit.
2. Connected via ssh to run your script.

   bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/raspberry.sh)"
   

   Answered yes to disable screen saver and use pm2 questions.

3. Removed chromium with:

   sudo apt-get remove chromium-browser
   sudo apt autoremove
   

4. Added Firefox with:

   sudo apt-get update
   sudo apt-get install firefox-esr
   

5. Enabled VNC using sudo raspi-config GUI
6. Connect via TigerVNC
7. Edit mm.sh via VNC in Pi's baked-in text editor by adding:

   cd ~/MagicMirror
   export external_browser=firefox
   DISPLAY=:0 npm start
   

8. sudo reboot

9. Connect via ssh

10. cd MagicMirror
    pm2 start MagicMirror
    

11. And now -- finally! -- some progress:

    [PM2] Spawning PM2 daemon with pm2_home=/home/dvg/.pm2
    [PM2] PM2 Successfully daemonized
    [PM2][ERROR] Script not found: /home/dvg/MagicMirror/MagicMirror
    

So … now what have I done wrong? What script is missing?

[sdetweil]

@davidgagne well…

it seems the pm2 setup failed for some reason

can you send me the ~/install.log

my same userid at Gmail.

you didn’t have to vnc to edit, nano works over ssh.

because the pm2 setup was not completed,
when you did pm2 start from the MagicMirror folder, it was trying to create the app MagicMirror command
/home/username/MagicMirror/MagicMirror

can you try to run the fixuppm2 script from my scripts page

@sdetweil Here’s what I got after running your fixup script:

I’ll email install.log to you as soon as I can figure out how to … find and copy the install log.

[sdetweil]

@davidgagne and MagicMirror should have come up using firefox

you should install one of the windows ssh clients tools. Winscp or Bitvise ssh clients.
they provide the typical ssh terminal AND also a windows file manager view of the remote system.
so you can double click to edit on windows and automatically save the file back.

bitvise also provides drag and drop file copy support to/from the remote system… for logs and credential files

I use notepad++ or visual studio code to edit on windows.

such a time saver!!

[davidgagne]

@sdetweil I am not going to bother sending you the install log because it worked!

It took a long time to launch, but now I can see MagicMirror running when I VNC into the Pi.

After running your fixuppm2 script I executed pm2 start MagicMirror and got this:

[PM2] Applying action restartProcessId on app [MagicMirror](ids: [ 0 ])

Now when I VNC into the Pi I see it running! So far the date and time is the only thing correctly displaying, but at least now MagicMirror is running. Thank you!

[sdetweil]

@davidgagne I am interested in the log to see why the inline pm2 setup failed.

yes, pi0w is not fast.

the default calendar and weather take configuration before they produce output.

[sdetweil]

@davidgagne you can also adjust the MagicMirror config so you can open your windows browser to see it too.
