Hi,

Last week I setup a Pi with the Pi display and noticed this too.
As I only was interested in testing 1 module, I did not bother too much.
Most persons of course use HD, full HD or even higher pixel density.
The modules do not care about your screen and have their own sizes, characters sizes, margins, etc.
They do not auto-adjust, in general, perhaps there are exceptions.
I do not known about generic settings that can be adjusted, so it seems you will need to adjust each module in the custom.css.
Personally I think there is only space for max. 4 modules per screen/page.
There are modules that can rotate pages or even rotate modules in 1 page, allowing you too run more modules.

This will supply you with a bit more effective total space:

body {
  margin: 1px;
  height: calc(100% - 1px);
  width: calc(100% - 1px);
}

For starters.

Hi,

I found this to keep the pm2 log under control, pm2-logrotate:

http://pm2.keymetrics.io/docs/usage/log-management/#pm2-logrotate-module

Of course the module needs to be fixed, but this could prevent you from getting a full log again.

I do not have it in use myself.

@bill22
In the config part add

rotateStreams: true,
rotateStreamTimeout: 60,

and add 2 or more streams (stream1 and stream2).

Hi,
I have no idea what you mean with “first pi code” and “the other code”.
2 Pi’s with 2 Magic Mirror instances running?

Do you have ssh access to your Pi 4?
If / is 100% full it normally does not allow you to.
You need to have access again and disable all your modules.
Then check if the / usage is increasing.
If not, or in normal quantity, then allow the modules again one by one, checking the usage after every step.

A reboot might grant you access again, or you might need to take the card out and use a card reader to have access via your PC.
Cleanup /tmp and try to boot from it with your Pi again.

Free space :

sudo df -h /

Usage:

sudo du -sh /
sudo du -sh /tmp 
sudo du -sh /home/pi

Until you have access, trouble shooting is not possible.

Good luck.

@dazza120

I would suspect either /tmp being filled up or some log directory being filled up.
Or a log file going AWOL.

You can try to find out which directory under / is using the most:

$ sudo find / -xdev -maxdepth 1 -type d -exec du -s {} \; | sort -rn

When it is working again (perhaps after a reboot you have enough space again), you can look periodically which files are touched / created in the last 60 minutes:

$ sudo find / -xdev -mmin -60 -type f -exec ls -als  {} \;

I wrote a small post on this topic.
JSON is supposed to be easy and straightforward, but when there is nested data it can get quite complex.

I guess the keywords are css canvas circle.
Something for the make-up artists on the forum.

Hi,

I used this Sunday to setup a second Pi, whilst watching F1.
Used a new SD, installed Debian Buster and Magic Mirror v2.8.0.

After I made sure I did not have any errors after rebooting, restarting MM, etc, I setup MMM-RTSPStream.
It now works for Bucks Bunny, my IP cam and my SAT receiver.
I can even rotate 2 SAT channels.

I also tested the little fix with --audio_queue 4and that works to (although I cannot check audio, as I have no speaker).

It does not say that this method will work for you (my RTSP was dead as a dodo), but it could be something to consider.
I will play a bit with single quotes, double quotes, etc, as that is a potential problem in your URL.

And it still leaves the issue with selecting a channel at will, through a trigger.

@bill22

Btw, do you “fancy” stuff like Voice Control or Alexa ?
I don’t, but those would be modules that could trigger something.

@bill22

I will look if there is a module that can trigger linux commands at will.
Would be interested in that myself.
