MMM-Hoymiles-Wifi

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.

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'

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-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

Great job! It could work for me. Unfortunately it’s dark outside but I can see the gauge on my mirror.

I don’t even dare to ask, but do you have a hint how about resizing it? I tried it with width and height but it won’t work.

 {
    module: "MMM-HoymilesPVMonitor",
    disabled: false,
    header: "PV Monitor",
    position: "top_left",
    width: "100px",
    height: "105px",
    config: {
      dtuIp: "192.168.178.150",        // IP address of your Hoymiles DTU
      maxPower: 800,                  // Maximum system power in watts
      updateInterval: 5 * 60 * 1000   // Update interval in milliseconds (default: 5 minutes)
    }
  },

Many thanks and kind regards

@Jose1701 said in MMM-Hoymiles-Wifi:

width: "100px",
height: "105px",

those are outside the config:{} section, that means they are for the MM runtime…
but we don’t process width/height

if you want to do this you need to learn to use css(cascading style sheet) to customize the html presentation
ALL updated css goes in css/custom.css

a css entry in custom.css is

selector_clause {
   styles to apply to elements selected by the selector clause
}

we add the modulename as a class to the web content so that one can ‘select’ only for that module

key selector clause elements
starts with . means element has classname=xxx
starts with # means element has id=xxxx
does not start with either, means html element name, div, span, p, h1, img…

@sdetweil

Alright, I will try to get some info in the internet. Never done sth with css.

Thanks

sdetweil

@Jose1701 I understand , the browser provides a developer environment with different capabilities

logger
code execution
and elements viewer, css tester env

see the second link in my signature below for a starter course on the elements tab.
