Trying to write my own Module...

@mochman Thanks for sharing the link to the w3 schools page! I managed to get it working by following the example on the website. Glad I learned something in the process! Happy New Year!

@mochman ->

How would I go about formatting my table? I would like to have each column have it’s own title, like “Load” and “kWh”. Is it also possible to put them into a tabulated table?

My getDOM currently looks like the following:

getDom: function(){
        var wrapper = document.createElement("div");
        if(!this.loaded) {
                wrapper.innerHTML = "Loading...";
                return wrapper;
        }
        if(this.xml !== null){
	 var table = document.createElement("table");
         table.classList.add("xsmall", "table");
         var channels = this.xml.getElementsByTagName("channel");
         for(var i = 0; i < channels.length; i++){
	   var row = document.createElement("tr");
           for(var n = 0; n < channels[i].children.length; n++){
		name = channels[i].getAttribute('name');
		if(channels[i].children[n].tagName === "kWh"){
                var element = document.createElement("td");
		element.classList.add(channels[i].children[n].tagName);
		if (channels[i].children[n].textContent != 0){
			element.innerHTML = name + channels[i].children[n].textContent;
			row.appendChild(element);
			table.appendChild(row);
			}
		}
		
		
           
	   
           }
         }
         wrapper.appendChild(table);
        } else {
                console.log("Returned no Data");
                wrapper.innerHTML = "NO DATA";
        }
        return wrapper;
   },

   parseXML: function(xmlStr){
        return ( new window.DOMParser() ).parseFromString(xmlStr, "text/xml");
   }

You should just need to put

var row = document.createElement("tr");
var header = document.createElement("th");
var header2 = document.createElement("th");
header.innerHTML = "Load";
row.appendChild(header);
header2.innerHTML = "KWh";
row.appendChild(header2);
table.appendChild(row);

before

var channels = this.xml.getElementsByTagName("channel");

You can add a title by modifying your config.js file to add a header.
The documentation for that is here.

@mochman Thanks a lot! I’ll take a look at the documentation and try your suggestion.

Have a good weekend!

@mochman I have another question. As shown below in the attached image, I am appending the name to the kWh values. How do I put the name into the Load column and the numbers into their kWh column?

In this case, the “name” is in the same object as the channel, so that’s why I extracted it the way I do in my code… I have the name as a variable, but I can’t seem to put it into it’s own column.

Code:

   getDom: function(){
        var wrapper = document.createElement("div");
        if(!this.loaded) {
                wrapper.innerHTML = "Loading...";
                return wrapper;
        }
        if(this.xml !== null){
	 var table = document.createElement("table");   
	 var row = document.createElement("tr");   
	 var header = document.createElement("th");
	 var header2 = document.createElement("th");
	 header.innerHTML = "Load";
	 row.appendChild(header);
	 header2.innerHTML = "kWh";
	 row.appendChild(header2);
	 table.appendChild(row);

	 table.classList.add("xsmall", "table");
         var channels = this.xml.getElementsByTagName("channel");	 

         for(var i = 0; i < channels.length; i++){	   	
		var row = document.createElement("tr");
           for(var n = 0; n < channels[i].children.length; n++){
		name = channels[i].getAttribute('name');
		if(channels[i].children[n].tagName === "kWh"){
                	var element = document.createElement("td");
			element.classList.add(channels[i].children[n].tagName);
		if (channels[i].children[n].textContent != 0){
			element.innerHTML = name + " " + channels[i].children[n].textContent;

			row.appendChild(element);
			table.appendChild(row);
			}
		}          	   
           }
         }
         wrapper.appendChild(table);
        } else {
                console.log("Returned no Data");
                wrapper.innerHTML = "NO DATA";
        }
        return wrapper;
   },

I am trying to begin the next iteration of my module.

I have the real-time energy usage, and monthly power usage being displayed in a list in the top left and right corners of my mirror.

I am hoping to do something similar to the following:

• Take a value from my Monthly Usage, and then display it in the center of my mirror with a sentence like, “Your monthly power usage is: XXX Watts”.

Since this monthly energy usage module is in the top right of my mirror, how would I extract a value or variable from that module and then display it into the center of the mirror.

So basically, I have a long list of power usages being displayed on my mirror, but I would like to display a sentence or two about that data on another part of my mirror - extracting a value from the module and displaying it in the center of the mirror. Can this be done using the same .js code in the module, and just modifying the .css?

@nbrenn the easiest solution without messing with the css around is to create a second module, which is litening on the broadcasts you will send with the data in it from your module you already have
