Trying to write my own Module...

yes the xmlhttprequest is also better known as ajax request
for each channel a row will be created and for name and watts a column will be created with their specific values
the data will still be displayed, but without any custom styling

I’m trying to display just the names where the watts that are != 0. I want both the values greater than 0 and the values less than 0 (in order to include the negative values from the solar generation).

I attempted to modify the getDom. It is displaying every names in the .XML and shows the watts value only if it is != 0. But how do I also remove the names that are 0? The output currently looks like the following:

Power Panel        66
Outlets            20
Heat Pump
Oven   
East Solar Panel  -70
West Solar Panel  -50

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++){
                if(channels[i].children[n].tagName === "name" || channels[i].children[n].tagName === "watts"){
                var element = document.createElement("td");
                element.classList.add(channels[i].children[n].tagName);
                if (channels[i].children[n].textContent != 0){
			element.innerHTML = 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;
   },

Looks like you need to modify your other if/then statement. The one you’ve modified checks both the name and watts to see if they are !=0. Since the name always !=0, it’s displayed.

nbrenn

It looks like the values are not updating. (The wattage values didn’t change at all overnight).

Should the line:

setInterval(this.getCurrentData(), this.config_interval);

be changed to:

setInterval(this.getCurrentData(), this.interval);

Are we calling the interval variable in the config incorrectly?

Thanks!

@nbrenn this.config.interval

For posterity, I modified the if statement as follows, to remove the row items that have a 0 for wattage:

if (channels[i].children[n].textContent != 0) {
     element.innterHTML = channels[i].children[n].textContent;
     row.appendChild(element);
     table.appendChild(row);
}
else {
     table.removeChild(row);
}

Glad it all worked out for you!

I’m working on getting historical data (my API has a function getHistoricalData). The XML looks like the following:

<Time Time="2016-11-03 00:00:00">
<channel channel="194882" name="Main Power Main Panel">
<kWh>0.319</kWh>
</channel>
<channel channel="194885" name="Outlet 1">
<kWh>0.000</kWh>
</channel>
<channel channel="194886" name="Solar Panel 1">
<kWh>-5.737</kWh>
</channel>
<channel channel="194887" name="Solar Panel 2">
<kWh>-4.877</kWh>
</channel>

The difference between this XML output, and the XML output from my getCurrentData call, is that name is not it’s own element. With the old function, <name> was in brackets. Now, it is name = ....

Would be getDom be the same as it was for getCurrentData, or is it different since it’s name= and not it’s own <name> ... </name>

You’re going to have to modify the code to get that info. Take a look here for info on how it’s done.

@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!
