@strawberry-3.141 Yes, pasted below are the two files. I am new to JS modules and node.js servers so I was not aware you had to log if you’re receiving a notification. What are you notifying and where do you declare the notification? Do you know of any good documentation on this? I pasted in the code ianperrin suggested to see if it would work but it still displays this.temp as undefined. I must be missing something basic. Thanks for the help!

/* global Module */

/* Magic Mirror
 * Module: Bike

 * MIT Licensed.
 */

Module.register("bike",{	

// Default module config.
defaults: {
	text: "Hello good!"	
},
start: function() {
	this.temp = "This should change";
},
notificationReceived:function(notification, payload, sender) {
    if (notification === 'Temperature' && sender.name === 'currentweather') {
        var currentweather = payload;
        if ( currentweather && currentweather.hasOwnProperty('temperature') ) {
            this.temp = currentweather.temperature;
            Log.log('The current temperature is ' + currentweather.temperature);
        }
    }
},	
// Override dom generator.
getDom: function() {
	var wrapper = document.createElement("div");
	var myTemp = document.createElement("div");
	myTemp.innerHTML=this.temp;
	
	wrapper.innerHTML = this.config.text;
	wrapper.appendChild(myTemp);
	return wrapper;
  }
});

Here is the current weather function that contains the submission.

processWeather: function(data) {
	this.temperature = this.roundValue(data.main.temp);
	
	if (this.config.useBeaufort){
		this.windSpeed = this.ms2Beaufort(this.roundValue(data.wind.speed));
	}else {
		this.windSpeed = parseFloat(data.wind.speed).toFixed(0);
	}


	this.windDirection = this.deg2Cardinal(data.wind.deg);
	this.weatherType = this.config.iconTable[data.weather[0].icon];

	var now = new Date();
	var sunrise = new Date(data.sys.sunrise * 1000);
	var sunset = new Date(data.sys.sunset * 1000);

	// The moment().format('h') method has a bug on the Raspberry Pi.
	// So we need to generate the timestring manually.
	// See issue: https://github.com/MichMich/MagicMirror/issues/181
	var sunriseSunsetDateObject = (sunrise < now && sunset > now) ? sunset : sunrise;
	var timeString = moment(sunriseSunsetDateObject).format('HH:mm');
	if (this.config.timeFormat !== 24) {
		//var hours = sunriseSunsetDateObject.getHours() % 12 || 12;
		if (this.config.showPeriod) {
			if (this.config.showPeriodUpper) {
				//timeString = hours + moment(sunriseSunsetDateObject).format(':mm A');
				timeString = moment(sunriseSunsetDateObject).format('h:mm A');
			} else {
				//timeString = hours + moment(sunriseSunsetDateObject).format(':mm a');
				timeString = moment(sunriseSunsetDateObject).format('h:mm a');
			}
		} else {
			//timeString = hours + moment(sunriseSunsetDateObject).format(':mm');
			timeString = moment(sunriseSunsetDateObject).format('h:mm');
		}
	}

	this.sunriseSunsetTime = timeString;
	this.sunriseSunsetIcon = (sunrise < now && sunset > now) ? "wi-sunset" : "wi-sunrise";

	this.sendNotification('Temperature', {temperature:this.temperature});

	this.loaded = true;
	this.updateDom(this.config.animationSpeed);
},

Ok,

I am making a module that wants to use the current temperature from the default Currentweather module. In the README file for modules it appears that I can just have the currentweather module call the sendNotification() function and my module will receive it with the notificationReceived() function. For example,

In the currentweather.js file:

this.sendNotification('Temperature', {temperature:this.temperature});

In the receiving .js file:

notificationReceived: function(notification, payload) {
	if(notification === 'Temperature')
			this.temp=notification;
},

Am I missing something? I dont think I would have to create a node_helper to have one module send a payload to another. The issue I am getting is that this.temp remains undefined and I don’t know why this is happening.

Thanks!
