Or start mirror in Dev mode, not full screen

npm start Dev

Alt-tab will also walk u between the available windows

cd MagicMirror/
npm start

Then the black screen opens and i can’t see whats in the command line because if i want to stop MM i have to reboot the pi (I’m a total beginner, sorry, maybe there is an other possibility to stop without reboot).

I despair :loudly_crying_face:

node.js, long lines, single quotes, and whitespace mess

may have to comment out a few trailing commas…

should find the problem, if its config text related…

otherwise

start the mm from the commandline on the pi and see what the error reports,

@yawns same problem, nothing else than a black screen

But you did run npm install in ~/MagicMirror/modules/MMM-DHT-Sensor ?

		units: "metric"

{
	module: "MMM-DHT-Sensor",
	position: "bottom_right",
	config: {
		sensorTyp: 11,
		sensorPIN: 7,
		updateInterval: 2000,
		animationSpeed: 0,
		titleText: "Raumtemperatur",
		units: "metric",
	}
},

Befor i added the DHT-module, my MagicMirror was running. Here is my complete config.js file:

if (typeof module !== "undefined") {module.exports = config;}

And ending after the close brace of config

This new close brace, also needs a trailing comma
