Installing on a Pi Zero

sdetweil

@ebolisa i would rebuild the sd card and start again

ebolisa

@sdetweil I agree but which OS should I use? The lite one?

sdetweil

@ebolisa full desktop

ebolisa

@sdetweil Thank you! Finally got it going. I had to change the SD card.

Now I can finally replace my P4 with the P0. The P4, along with the display, are causing heat related problems so, P0 to the rescue.

Just FYI, I cannot hide the cursor and sudo apt-get install unclutter didn’t help.

sdetweil

@ebolisa in css/main.css body should have cursor:none

you are running chromium-browser, not electron, but should have been the same

sdetweil

@ebolisa pi0 doesnt have a lot of power, so beware running too much…

check swap space usage

free -m

to see if it needs to be made bigger

ebolisa

@sdetweil Yes, I set swap to 1024. It’s slow but it works.
Thanks again!!

@sdetweil , I went through a fresh SD card install for a Pi Zero W. raspbian and then the raspberry.sh script via your github page. I believe everything completed without error.

However when Magic Mirror launches on reboot, I get a blank page indicating:

This site can’t be reached
localhost refused to connect

Any idea what to do to troubleshoot?

sdetweil

@rushhour99 is this with extra modules or just the base?

can u show the output of

pm2 logs --lines=100

@sdetweil said in Installing on a Pi Zero:

pm2 logs --lines=100

This just the Magic Mirror base. I haven’t added any extra modules.

Unfortunately I cannot paste the pm2 logs output. When I try it gets caught in some sort of spam filter and won’t let me post.

sdetweil

@rushhour99 u can email to me… same userid on gmail

also attach /home/pi/install.log

RushHour99

@sdetweil Thanks, error log emailed. Ive done this process before without error ~9 months ago. Maybe the rasbian version or magic mirror version has changed recently that is now causing the problem.

sdetweil

@rushhour99 there is a new MM version every 2 months…

I test on my own pi 0 .

haven’t seen a problem like this

sent email back, can u send install.log

sdetweil

@rushhour99 do this

sudo npm i -g npm@6

this will downgrade npm to v6

then

cd ~/MagicMirror
rm -rf node_modules
rm package-lock.json
npm install --only=prod

and check if the config.js file exists

ls ~/MagicMirror/config/config,js -laF

sudo npm -i npm@6

I got an error. Thanks for helping out, this is a new build so I don’t mind if it gets messed up and I need to start over.

$ sudo npm -i npm@6

sdetweil

@rushhour99 typo, sorry

sudo npm i -g npm@6

RushHour99

@sdetweil Thanks!

I copied the config.js.sample to config.js before running the downgrade commands.

After downgrading and rebooting, the Magic Mirror showed up on my Pi 0 with the default configuration.

sdetweil

@rushhour99 great, thanks for the update

I pushed a change to the installer to prevent npm going to v7.

I recently purchased a pi0, and installed MagicMirror successfully. However when I go to install more modules, it starts to fail (ie. become very unstable). Other than just ‘upgrading’ to a Pi3/4, is there any reason why I couldn’t host the mirror on my website and just use the browser to display the data?

what do u mean?

this is a programmed app… its not just a web page.

did u increase the swap space… pi0 doesn’t have much memory…

and its under powered, so it can’t do everything that a pi3 or 4 could do…
