How did you install MagicMirror, did you use the automatic installation?

pm2 restart MagicMirror && pm2 log MagicMirror

Hier bekomme ich nur eine Fehlermeldung: Kommando nicht gefunden

pi@Door:~/MagicMirror $ npm start

> magicmirror@2.3.1 start /home/pi/MagicMirror
> sh run-start.sh

Ist es normal das die Helper Module nicht gefunden werden?

Da ist keine location in deiner config angegeben, es sei denn, du hast die id durch die *** ersetzt.

@MichaelS said in Wetter wird nicht angezigt:

module: “currentweather”,

heißt das Modul currentweather? oder MMM-Wounderground?
unter Modul muss der Name des Moduls stehen der gleich mit dem Name des Ordners ist

Das default Modul heisst currentweather. Soweit ist alles richtig.
MicharlS: hast du mal gemacht, was idoodler gesagt hat? Logs könnten weiterhelfen.

module: “currentweather”,

heißt das Modul currentweather? oder MMM-Wounderground?

Warum umbenennen?

because the Mainprogram looks for a file named config.js without this file it dontn know what to display

Are the other modules showing?

var config = {
	address: "localhost", // Address to listen on, can be:
	                      // - "localhost", "127.0.0.1", "::1" to listen on loopback interface
	                      // - another specific IPv4/6 to listen on a specific interface
	                      // - "", "0.0.0.0", "::" to listen on any interface
	                      // Default, when address config is left out, is "localhost"
	port: 8080,
	ipWhitelist: ["127.0.0.1", "::ffff:127.0.0.1", "::1"], // Set [] to allow all IP addresses

It’s probably best to share your config with us. Just remember to remove anything you don’t want to share (e.g. API keys, maybe location etc.).
