Raspberry Pi Zero W for Magic Mirror

davidgagne

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

Flashed card with Legacy 32-bit.

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.

Removed chromium with:

sudo apt-get remove chromium-browser
sudo apt autoremove

Added Firefox with:

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

Enabled VNC using sudo raspi-config GUI
Connect via TigerVNC

Edit mm.sh via VNC in Pi's baked-in text editor by adding:

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

sudo reboot
Connect via ssh
```
cd MagicMirror
pm2 start MagicMirror
```

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

davidgagne

@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

sdetweil

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

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

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:

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.

davidgagne

@sdetweil I’m an Apple user. I am sure there’s something similar, though. Thanks.

davidgagne

@sdetweil It looks like I spoke too soon. After a reboot, I cannot seem to get any output from MagicMirror.
I rebooted and then called pm2 start MagicMirror from within the MagicMirror directory, and it seems to execute just fine. But … nothing happens. It doesn’t actually start the app, as far as I can tell. Even though the output seems the same:

Any ideas?

sdetweil

@davidgagne pm2 logs --lines=75

sdetweil

@davidgagne that circle with the arrow heading column says times restarted. 148 is a problem

davidgagne

@sdetweil I emailed you the output from that. I’m guessing Error: Cannot find module 'electron' is bad?

davidgagne

@sdetweil It’s frustrating because I swear it was working before I rebooted.

davidgagne

@sdetweil If you thought 148 restarts was bad … This is what I see now:

sdetweil

@davidgagne got it. Just back from my walk… will examine…

davidgagne

@sdetweil I followed your tutorial on adding the Jeopardy module (just to see what would happen) and it worked fine. The last step is npm start and when I did that I got this:

@davidgagne yep,

not my tutorial just one I reference

see this

@sdetweil Hmmm. Okay. I tried that for the ‘alert’ module but it didn’t seem to have any impact:

Same result; just a bunch more restarts and nothing appearing. (The Pi desktop is there, though.)

sdetweil

@davidgagne why alert? it’s the mmm-jeopady module that is missing a library
