GIF update from URL with MMM-EyeCandy

JRWJR

Weather radar is a tough thing to solve, but I stumbled across a solution if I can get a module like MM-EyeCandy to do an update pull from the URL.

	{
        module: "MMM-EyeCandy",
        position: "bottom_right",
        config: {
            maxWidth: "50%", // Sizes the images. Retains aspect ratio.
            //style: "1",            // 1 - 52 or use ownImagePath to override style
            ownImagePath: "https://icons.wxug.com/data/weather-maps/radar/united-states/united-states-current-radar-animation.gif", // ex: "modules/MMM-EyeCandy/pix/YOUR_PICTURE_NAME.jpg", or internet url to image
            //ownImagePath: "https://icons.wxug.com/data/weather-maps/radar/united-states/san-antonio-texas-region-current-radar-animation.gif",
            updateInterval: 10 * 60 * 1000,
        }
    },

It does not appear the updateInterval is working unless it is throwing the following error when isolated.

Whoops! There was an uncaught exception…
TypeError: Cannot read property ‘hash’ of null

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues

Any ideas?

I’ll take a look at this tonight

I think this should work; add the following at the bottom of the start function in MMM-EyeCandy.js:

  start: function () {
  
    ...
      
    // ADDED: Schedule update timer
    setInterval(function() {
    self.updateDom(self.config.fadeSpeed || 0); // use config.fadeSpeed or revert to zero
    }, this.config.updateInterval);

  }, // this was line 83

Thanks ninja. I was a little tied up last night with yesterday’s Nor’Easter slamming NYC late into the evening. If you don’t mind, I’ll just incorporate that into the module when I get home from work.

Peace!

Thanks again but the problem still exists. Let me explain what I’ve done so far.

Added your setInterval(function().
Tried to seed the url of the .gif file with a timestamp but that was rejected with a 404 error.
Added a timestamp div/tag so I could check if the module was actually updating. It is.

This url is not refreshing upon updateDom but the timestamp is.

I’m lost.

@Mykle1 How did you seed the url with a timestamp? When I visit https://icons.wxug.com/data/weather-maps/radar/united-states/united-states-current-radar-animation.gif?1521767776, I get the image returned (not a 404).

@ninjabreadman

Like this, because I need the seed to change. Feel free to tell me what I’m doing wrong. Hehe

var getTimeStamp = new Date().getTime();
img.src = "https://icons.wxug.com/data/weather-maps/radar/united-states/united-states-current-radar-animation.gif&seed=" + getTimeStamp;
pic.appendChild(img);
wrapper.appendChild(pic);

@Mykle1 Yep, just needs to be a ? before the first parameter. Anything after gets appended with an &, e.g. https://icons.wxug.com/data/weather-maps/radar/united-states/united-states-current-radar-animation.gif?seed=1521767776&otherseed=4846528&page=2.

Making your code the following:

... // img creation, etc
var getTimeStamp = new Date().getTime();
img.src = "https://icons.wxug.com/data/weather-maps/radar/united-states/united-states-current-radar-animation.gif?seed=" + getTimeStamp;
pic.appendChild(img);
wrapper.appendChild(pic);

Making your code the following:

That did the trick. The .gif file is refreshing to reflect the new data when it changes.

Thanks for the lesson. I do appreciate the help.

Peace!

I will post the update on github shortly. Thanks to our friend, @ninjabreadman, the module now works as it should.

EDIT:

A git pull in the /MagicMirror/modules/MMM-EyeCandy folder will fix you up. Please take note of the changes to the config.js entry. Also, please take into account that the url you gave only updates itself about every 15 minutes.
