A pity it does not work for you.
Strange that is only happens after a several hours
But mplayer is rather old, perhaps that is the primary issue.

Still, I tried it on my Pi 3b with 1Gb RAM and it runs well.
It is 3 to 5 seconds lagging.
Like the stream on my P4b with 8Gb.
It also does not seem very memory hungry.

Pi 3b is steaming now for over 2 hours, so I will need to look later again to see if it got messed up.
The Pi 4b is streaming for 2 weeks straight now, without issues.

To me it looks more like a camera issue, but if you say that other players have no issues …
Somehow mplayer does not like your rtsp stream, or it is a combination of factors.

I have found that there is a config file, where you can set options.
Try out some options (need to restart MagicMirror after every change).
For example try nocache first.
Then try cache=65536.
The option nosound is always good (can be set in the MMM-Mplayer options too, if not already done so).
The bandwidth option is just a shot in the dark.

$ vi ~/.mplayer/config
# Write your default config options here!

# No cache
nocache=yes

# Cache size in kBytes (4MB / 8MB / 16MB / 64MB)
# cache=4096
# cache=8192
# cache=16384
# cache=65536

# Do not play/encode sound
nosound=yes

# Bandwidth (10MB / 100MB / 1000MB)
# bandwidth=80000000
bandwidth=100000000
# bandwidth=1000000000

What also can be the case, is that the windowSize is not matching your stream resolution.
This can cause issues as it needs to recode this portion.
Try:

windowSize: { width: 960, height: 540 },

for a 1920x1080 (16:9) stream.

That is all I can think of.
Good luck.

@plainbroke said in pm2 doesnt work with crontab:

@evroom,
I get that nothing is found, when I run either of your suggestions.

The journalctl -f shows the current activities.
Simular to tail -f <filename>.
So when there are none, you will see none.
Use that when you know that a cron job is going to occur anytime soon.
The --since "1 hour ago" searches for activities in the last hour.
Change to, for example --since "24 hours ago" for activities in the last 24 hours.
When nothing comes out, then indeed nothing happened (during the time period you are searching in).

Other --since options:

"today"
"00:20"
"2025-11-12"
"2025-11-12 07:30:00"

About /var/log/syslog.
Debian does not use that anymore, already since a while.
As far as I understand it, you will need to get familiar with journalctl.
For cron jobs try this:

$ journalctl --since "1 hour ago" --unit cron.service

$ journalctl -f -u cron.service

Happy hunting.

@Jose1701

No, sorry, no idea.
What Sam says, but that needs knowledge.
But I opened an issue/request, so let’s see if it will be granted:

@Jose1701

Remove the old module from the config:

$ vi ~/MagicMirror/config/config.js

Remove the "MMM-Hoymiles-Wifi" config, or set:

    module: "MMM-Hoymiles-Wifi"
    disabled: true,

Delete HoymilesWifi from pm2:

$ pm2 stop HoymilesWifi
$ pm2 delete HoymilesWifi
$ pm2 save

If desired, completely remove the old module:

$ cd ~/MagicMirror/modules/
$ rm -rf MMM-Hoymiles-Wifi

Install MMM-HoymilesPVMonitor:

$ cd ~/MagicMirror/modules

$ git clone https://github.com/CuddlyCow/MMM-HoymilesPVMonitor.git

@Jose1701

Yeah, stopped is not good.
I will need to get it working myself before I can give more useful information on what to check.
Will keep you posted.

@Jose1701

>> You installed that already, so no need to install it again.
>>The schris88 requirements.txt contains the hoymiles-wifi package.

If you want to repeat it under the new module name, then you will need to copy the requirements.txt file from the previous module.
But again, since you already did this, no need to repeat.

@Jose1701

You installed that already, so no need to install it again.
Probably using:

python -m pip install -r requirements.txt --break-system-packages

The schris88 requirements.txt contains the hoymiles-wifi package.

@Jose1701

You also might try this module:

https://github.com/CuddlyCow/MMM-HoymilesPVMonitor

I may give it a try myself.

@Jose1701

First of all, where I write

/home/admin/

please use

~/

(tilde sign)

And can you please send me:

cd ~/MagicMirror/modules/MMM-Hoymiles-Wifi
git branch
git remote -v

Every time you get that port in use error, run the long command to see what programs are using the port.
And of course do not use HoymilesWifi.sh when it is also active under pm2.

I am starting to wonder if the module works at all.
I finally got a picture, but it showed an error in it.

To be honest, for me the MM does not display anything.
Although it is dark, I still expected the graphic with 0 or so.
Or I have to wait a bit longer.

I used
https://github.com/schris88/MMM-Hoymiles-Wifi/
and all the above is correct and running.

A year ago I made a fork and made some changes, of which I think are present in the schris88 version as well.

https://github.com/evroom/MMM-Hoymiles-Wifi/
I will give this one a try when I have time.

PS: it seems that when the microinverter is off-line, you will not see anything. Need to wait for it to be active again.

@Jose1701

First I would disable the module:

$ vi ~/MagicMirror/config/config.js

    module: "MMM-Hoymiles-Wifi",
    disabled: true,

$ pm2 restart MagicMirror

I build this command to try to get more info on port 5000:

$ for pid in `lsof -i :5000 | grep -v 'PID' | awk '{print $2}' | sort -u`; do echo $pid; ps -Flww -p  $pid; done

Hopefully the Forum tool does not change it.

Furthermore please verify and supply the following data:

$ cd /home/admin/MagicMirror/modules/MMM-Hoymiles-Wifi

Check path:

$ which hoymiles-wifi
$ echo $PATH

Check if the path is in the PATH.
If not, do (using the path from ‘which’):

$ export PATH=$PATH:/home/admin/.local/bin

Check config.js:

$ grep ':5000' ~/MagicMirror/config/config.js

Expected is:

{ src: 'http://127.0.0.1:5000' },

Check HoymilesWifi.sh:

$ grep 'dtu_ip_address' HoymilesWifi.sh

Expected is your DTU IP address, for example:

python hoymiles_data.py --dtu_ip_address 192.168.178.50 --max 800

Test run (hoymiles-wifi):

$ hoymiles-wifi --host 192.168.178.50  identify-inverters

Expected is a response.

Test run (HoymilesWifi.sh)

$ ./HoymilesWifi.sh

Expected is:

* Serving Flask app 'hoymiles_data'
* Debug mode: off
INFO:werkzeug:WARNING: This is a development server. Do not use it in a production deployment. Use a production WSGI server instead.
* Running on http://127.0.0.1:5000
INFO:werkzeug:Press CTRL+C to quit

If you wait a bit some more output is shown.

If it works, then I would suggest to stop the ./HoymilesWifi.sh command and do:

$ cd /home/admin/MagicMirror/modules/MMM-Hoymiles-Wifi
$ pm2 start HoymilesWifi.sh
$ pm2 save

$ pm2 status HoymilesWifi

$ pm2 logs HoymilesWifi --lines 10

If everything is okay, the enable the module again:

$ vi ~/MagicMirror/config/config.js

    module: "MMM-Hoymiles-Wifi",
    disabled: false,

$ pm2 restart MagicMirror

@Jose1701

Yes, so an instance is already running.
You added it to pm2 too?

pm2 status

If yes, then you do not need to run it manually.
If no, then kill the (p)pid.

sudo kill -9 [ppid]

@Jose1701

This command should give more information on the PID found:

ps -Flww -p

E.g.

ps -Flww -p 64879

Perhaps there are easier ways, but this should do.

@Jose1701

Try this to find out what is using port 5000:

sudo netstat -apln | grep -w 5000

And did you update the bash program?
https://github.com/schris88/MMM-Hoymiles-Wifi?tab=readme-ov-file#enter-dtu-ip-address-of-dtu

@Jose1701

The
};
needs to be
},
So a comma iso of a semicolon.

@ge

I have almost the exact environment and Raspberry Pi.
I am running MM version 2.33.0, but that should not matter IMHO.

Btw, have 8Gb, and you ?

vcgencmd get_config total_mem

Can you open the RTSP URL in VLC and then open Window - Media Information ?
Then the Codec Details tab and please provide the Codec, Video resolution and Frame rate information.
I have H.264, 2560x1440, 25.

And can you try to change the config to this (add 2 lines):

    windows: [
      {
        windowSize: { width: 990, height: 557 },
        windowPosition: { x: 471, y: 20 },
        rtspStreamOverTcp: true,
        noSound: true,
        streams: [
           'rtsp://admin:Camadmin@172.16.0.37:554/cam/realmonitor?channel=1&subtype=0'
                 ]
      }
    ]

From looks the RTSP URL you are using a Dahua cam, right ?
Maybe you can try subtype=1 ??
Or another channel perhaps.
I do not know the relation between channels and resolutions.
Try to find a lesser resolution to see if it makes it better.

Also good to know how many other applications are streaming, for example Synology Surveillance Station.

@ge

You may have seen this example config.
I am using this for my Axis P1448-LE.
It works okay, but is sometimes lagging, not stuttering.

https://github.com/evroom/MMM-MPlayer?tab=readme-ov-file#config-example-for-a-single-window-single-rtsp-stream

There is also a section on data gathering:

https://github.com/evroom/MMM-MPlayer?tab=readme-ov-file#data-gathering

You can supply me with this data and your config, then I can have a look at it.

@plainbroke
Happy to help.

@plainbroke

Can you please provide me with the output of:

$ grep Version /home/admin/MagicMirror/modules/MMM-MPlayer/node_helper.js

And the commands found in this section of the README:

https://github.com/evroom/MMM-MPlayer?tab=readme-ov-file#data-gathering

I have a feeling you have placed the config from the old version into the ‘new’ version.
Or in other words: you installed version 2…0.1, without changing the config accordingly, which has changed quite a bit.
See https://github.com/evroom/MMM-MPlayer?tab=readme-ov-file#config-example
