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

$ cd MMM-HoymilesPVMonitor

$ git branch
* main

$ git remote -v
origin	https://github.com/CuddlyCow/MMM-HoymilesPVMonitor.git (fetch)
origin	https://github.com/CuddlyCow/MMM-HoymilesPVMonitor.git (push)

$ which hoymiles-wifi
/home/admin/.local/bin/hoymiles-wifi

$ echo $PATH
/home/admin/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games

$ vi ~/MagicMirror/config/config.js

      maxPower: 800,                  // Maximum system power in watts
      updateInterval: 5 * 60 * 1000   // Update interval in milliseconds (default: 5 minutes)
    }
  }


$ grep 'dtuIp' ~/MagicMirror/config/config.js
      dtuIp: "192.168.178.50",        // IP address of your Hoymiles DTU

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.

>> 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.

evroom

@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.

evroom

@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.

evroom

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]
