@sdetweil i tried that code, but it doesnt work. Still the same problem.
I always start the MM in the command line with:

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:

@yawns yes i did

@binia doesn’t work

@yawns same problem, nothing else than a black screen

@sdetweil i tried it but then there was a black screen with the massage i should create a correct config.js file.

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

Hi,
I need some help. I tried to install the DHT module from bernardpletikosa (https://github.com/bernardpletikosa/MMM-DHT-Sensor). But when i start my MagicMirror i onley get a black screen.
Did i anything wrog in my config.js file? This is what i added:

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

Thanks

@strawberry-3.141 Thanks, now the config file and the magic mirror surface are running but there is no response from the sensor. i have moved the potentiometer but the screen doesnt turn off. Do you know any possible mistake i could have made?

@johnnyboy yes i tried it like this :

               {
			module: 'MMM-PIR-Sensor',
			config: {
				sensorPIN: 23,
                                powerSaving: true,
                                relayPIN: none,
                                relayOnState: 1
			}
		},

But it dosent work. Same problem as before.

@pjkoeleman when i want to start the magic mirror it says that i should create a correct config.js file. But the only thing i added in my config.js file (which runs without the following lines) is:

               {
			module: 'MMM-PIR-Sensor',
			config: {
				sensorPIN: 23,
                                powerSaving: true,
                                relayPIN: none,
                                relayOnState: 1,
			}
		},

@johnnyboy But it doesnt matter as long as i use the gpio that belongs to this pin or am i wrong?
