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 -vEvery 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. -
You also might try this module:
https://github.com/CuddlyCow/MMM-HoymilesPVMonitor
I may give it a try myself.

* master origin https://github.com/schris88/MMM-Hoymiles-Wifi (fetch) origin https://github.com/schris88/MMM-Hoymiles-Wifi (push)I used the ~ symbol.

Well I tried that but I’m to silly to install it.
florian@raspberrypi:~/MagicMirror/modules/MMM-Hoymiles-Wifi $ pip3 install hoymiles-wifi error: externally-managed-environment × This environment is externally managed ╰─> To install Python packages system-wide, try apt install python3-xyz, where xyz is the package you are trying to install.

You installed that already, so no need to install it again.
Probably using:python -m pip install -r requirements.txt --break-system-packagesThe schris88 requirements.txt contains the hoymiles-wifi package.
-
By unsing this, I get the following error:
python -m pip install -r requirements.txt --break-system-packages Defaulting to user installation because normal site-packages is not writeable ERROR: Could not open requirements file: [Errno 2] No such file or directory: 'requirements.txt' -
>> 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. -
Okay. But in the end I can’t get it to work. Don’t know whats wrong …
Does this has to do with that:

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. -
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-WifiInstall MMM-HoymilesPVMonitor:
