@strawberry-3-141 thanks for the great advice.

Ive tried your advise. Nevertheless my screen is now completely black, too.

Ive tried it several times now, sometimes it works sometimes it doesn’t.

After Ive changed the API Key of openwjeathermaps my screen went black again.

So @strawberry-3-141 do you have and advise maybe? :-)

Kind Regards from Germany,

Paul

@PaulB A completely black screen usually means there is an error in the config.js file. Please post yours, (specifically the openweathermaps module entry) using the markdown features and we’ll take a look at it.

At a guess, it looks like you put the header for your module in the module name specification. The module: [name] lines must match the name of the module. These names also correspond with folders in the ~/MagicMirror/modules path. The modules that are installed with the MagicMirror code (which I believe you are trying to use) will be in ~/MagicMirror/modules/default/[module name]

So try this instead:

{
		module: 'currentweather',
		position: 'top_right',
		config: {
			location: 'Bayreuth, Germany',
			locationID: '5128581', 
			appid: '158010f0c45e255e6439eb1885b3482b'
		}
	},
	{
		module: 'weatherforecast',
		position: 'top_right',
		header: 'Wettervorhersage',
		config: {
                     location: 'Bayreuth, Germany',
		     locationID: '5128581',  
                     appid: '158010f0c45e255e6439eb1885b3482b'
		}
	},

@bhepler You are a Genius! Thanks a lot. :-)

Changing the module names was not my best idea, I guess :D

[PaulB]

Nevertheless the index.html-file shows me just a black screen.

[strawberry 3.141]

@PaulB the html file itself will show only a black screen, the modules get loaded dinamically so there is no point in open the html file in a browser, if you want to open the mirror onto another computer and type in the ip followed by the port specified in the config.js

@strawberry-3-141 Ah!Now I get it. Thank you very much for your help. :-)
