Raspberry Pi Zero W for Magic Mirror

sdetweil

@davidgagne ok, lets clean up and restart

all command line commands

pm2 flush (to get clear out the old logs) 

pm2 status

cd ~/MagicMirror
npm start

all show work… and if you loaded the missing library in the MMM-Jeopardy module then all should be ok.

then ctrl-q on the MM screen should stop it

then

pm2 restart 0

and MM should come back up

davidgagne

@sdetweil Okay! I’m doing this right now and will keep you posted. THANK YOU AGAIN.

davidgagne

`@sdetweil Sadly that didn’t seem to work at all.

pm2 flush gave me:

[PM2] Spawning PM2 daemon with pm2_home=/home/dvg/.pm2
[PM2] PM2 Successfully daemonized
[PM2] Flushing /home/dvg/.pm2/pm2.log
[PM2] Logs flushed

Then pm2 status gave me:

Then I did cd ~/MagicMirror/ and ran npm start which spit out this:

> magicmirror@2.27.0 start
> ./run-start.sh $1

This all seemed pointless, but I ran pm2 restart 0 anyway and got this:

At this point I’m going to give up and go back to square one and flash the drive again and start over. Ugh.

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

024-05-29 23:10:01.570] [ERROR] Error: Cannot find module ‘request’

/home/dvg/MagicMirror/modules/MMM-JEOPARDY/node_helper.js

no… just fix the MMM-Jeopardy module as I suggested yesterday

two steps
you only did 1

… the more concerning part is that pm2 didn’t get setup as a service and start on boot… i haven’t looked at the log yet

sdetweil

@davidgagne the install log looks good…

don’t know what is going on… will have to think on it while I sleep…

time to rest… til tomorrow

davidgagne

@sdetweil I understand what you’re saying about fixing the Jeopardy module, but I really think that’s secondary to not getting MM to run in the first place (and it not starting as a service on boot). Once I get MM running reliably in the first place I will play around with modules. :-)

How to Get MagicMirror to Run on a Raspberry Pi Zero W Rev 1.1

Late-May 2024

Huge thanks to @sdetweil for all his help!

Flash card with Legacy 32-bit.

Connect via ssh to run script:

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

Answer yes to disable screen saver and use pm2 questions.

Remove chromium with:

sudo apt-get remove chromium-browser
sudo apt autoremove

Add Firefox with:

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

Enable VNC using GUI (Interface Options):
sudo raspi-config
Connect via TigerVNC (Apple app)
Edit installers/mm.sh via VNC using Pi's baked-in text editor by adding:
```
cd ~/MagicMirror
export external_browser=firefox
DISPLAY=:0 npm start
```

Execute fix'em-up script:

bash -c "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/fixuppm2.sh)"

cd ~/MagicMirror/
pm2 start MagicMirror

sudo reboot

Note: On my Pi Zero W it takes a solid ten minutes from reboot to actually seeing MM output via HDMI.

sdetweil

@davidgagne thanks.

5 and 6 are optional
as 7 can be done with nano over ssh

   scroll down with keyboard arrow keys
   hit enter to add a line
   type the export line
   ctrl-x to exit nano, yes to save contents

8 and 9 over ssh
9 pm2 can be run from any folder location

davidgagne

@sdetweil Is there any reason why this same procedure would not work on a 3B+? I’ve tried with multiple different versions of the OS but it always seems to get stuck on “Updating packages …” and – as far as I can tell – there’s nothing meaningful in install.log. Is this install script unique to the Zero W?

sdetweil

@davidgagne no. the script works of any Debian based os. pi0 is SLOOOOOW…
but pi 3b+ should be ok. there should be a moving <-> while it’s updating… (haven’t figured out how to make that stand out more)

the script is doing apt get update, apt upgrade . this could take a while based on how much change since distro was released. over wifi, nothing I can do to speed it up.

I’ve tested on all the pi models. except the pi 1.
on odroid, Jetson nano, a chrome box and book running linux and a bunch of x86 distros., and macos Intel and arm.
I also tested on my arm chromebook, with the extra Ubuntu installed. install worked and server mode worked. no ui

if there is a problem, I’ll fix it. I’ll setup my 3b later.
