@sdetweil Thanks! I’ll make the change and see what happens when it should update mid-day tomorrow.

Or you could do this:

scheduleUpdate: function() {
       setInterval(() => {
           this.getMenuData();
       }, this.config.updateInterval); 
   },
    getMenuData: function() {
       this.sendSocketNotification('GET-MENU-DATA');
   }

At the top of the main js you set the interval:

updateInterval: 15 * 60 * 1000,

Then in the start section you call it:

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

Either the way Sam showed you or the above will work :)

@cowboysdude Thanks! I might switch to that. I’ve had to rework it a little because the URL wasn’t getting set except at the first call. I just moved setup for that into the getMenuData and I think it’s all working now. I’ll give it a day to run and see what happens tomorrow before I try messing with it again and update the file on github.

-updated to fix grammar

Sam is a REALLY smart guy so he gives you the smart guy answer…
I’m not as smart so I give you my dumb guy answer LOL

It will work either way … so now you def have an answer that works :)

nah, Sam is the LAZY guy… change as LITTLE as possible. especially for folks just starting out

Well, thanks to both of you! I can confirm it is finally working.

Now to update github. Someday I should write some documentation too.

@cowboysdude, I’m looking for the part where you “change” the XML data to JSON data. I’m trying to write a new MMM, but the data is presented in XML. I like the have it in JSON, so I can use it.

Maybe I read over it, but I cannot figure out where you do this.

sdetweil

@htilburgs there are a few xml to json modules

https://www.npmjs.com/package/xml2js

google search
‘nodejs xmltojson’

here is one with a just code, no extra libs

https://davidwalsh.name/convert-xml-json

@sdetweil , I’ve found them, but I don’t know how to use it in combination with the URL that creates the XML.

Indeed the last one with no extra libs looks promising. I tried to simply add this in the node_helper.js but getting stuck at how to use it.
I’ve looked into all the MMM Modules but cannot seem to find an example.

@htilburgs the url bring back the data with request

request(url, function(err, res, body) {
    // if no error and server was happy
    if(err == null && res.statusCode ==200){
    console.log(body);
    var json_data=this.xmlToJson(body)
    console.log("Speed[0] text is "+json_data.SD[0].SPEED.@attributes.TEXT)
}
});

when the server responds, the function is called and passed the data, body)
and then u would convert it from xml to json . using the last code

var json_data=this.xmlToJson(body)

then the json is accessed with the normal structure notation
(using the sample with the code in the last link)

json_data.SD[0].SPEED.@attributes.TEXT will be ‘1421’

SD is an array (multiple of same xml tags)

a little ugly in the data layour, could get rid of the @attributes thing with a small code change
