1. open a terminal type in cd ~/MagicMirror/config to change directory
2. nano config.js
3. After you made your changes press ctrl+x and confirm
4. change directory to parent directory cd ..
5. start the mirror npm start

the first prototype is nearly finished for the nhl module

@jproehl custom.css

.newsfeed div.light.small.dimmed {
  color: #e54a1b;
  font-size: 9px;
}

@istepgueu

Module.register("MMM-door-sensor",{

	// Default module config.
	defaults: {
		text: "Hello World!"
	},

	// Define start sequence.
	start: function() {
		Log.info("Starting module: " + this.name);
	},

	notificationReceived: function(notification, payload, sender) {
		if (sender) {
			Log.log(this.name + " received a module notification: " + notification + " from sender: " + sender.name);
			if (notification === "DOOR_STATE") {

				this.door_state = payload;			
	
				this.updateDom();				
			
			}
		} 
		
	},


	getDom: function() {

		var wrapper = document.createElement("div");
if(this.door_state){
		wrapper.innerHTML = '<img src=" + this.door_state + " />';
} else {
		wrapper.innerHTML = 'No door state present.';
}
		return wrapper;
	}
});

config mmm-button

{
                pin: 24,
                name: "power",
                longPress: {
                    title: "Power off",
                    message: "Keep pressed for 3 seconds to shut down",
                    imageFA: "power-off",
                    notification: "DOOR_STATE",
                    payload: "close.png"
                },
                shortPress: undefined
            }

you would therefore need a button released to send open.png

@zichao92 not only you had some more issues and sendCommand is a custom method

there is a first prototype on the develop branch

git clone https://github.com/fewieden/MMM-VocabularyTrainer.git
cd MMM-VocabularyTrainer
git checkout develop

[card:fewieden/MMM-VocabularyTrainer]

@Mykle1 you can go to every commit you’d like to go, but it’s easier to choose a specific tag

git clone ...
git checkout v2.1.0

@P-Bo726 if they won’t do it, there are also possibilities to reverse engineer their api

@Lahim because you changed the context by removing the arrow function, to preserve the context you have to do something like:

 if (this.config.remoteFile != null) {
  var self = this;
  this.complimentFile(function(response){
    self.config.compliments = JSON.parse(response);
  });
}

I can recommend @yawns and @ianperrin for this positions.

They helped a lot and made also some excellent modules.
