Scheduled restart for MM or module

  • Hi,

    I´m in the middle of building my first MM and know next to nothing about coding. Thanks to Google I came very far, but now I´m stuck.

    Here is my problem: I want to show the stream of my foscam camera to my mirror. I tried the module “MMM-ipCam” but i could not get it to work (it always returned “undefined object”). But I am able to see the stream in a browser via URL. So I got the iframe module and now the stream is shown on my mirror, yeah.

    But: The stream freezes after a few hours. Sometimes it runs for a day and a half, sometimes for only 10 hours. After restarting the mirror, all is fine again.

    This is what I already tried:

    • I copied the “update interval” section from the compliments module and inserted it in the iframe module. I thought this would fetch the stream every few minutes and solve the problem. I don’t even now if I did it right, but it did not help.

    • I looked up cron jobs and thought maybe I could start and stop the mirror every six hours. But since I know nothing about it and I did not find the right command to quit the mirror (I know start is npm start, but what would I say to quit…?) I gave up.

    Can you help me with a few lines of code that I can insert into the module or for restarting the mirror?

  • @CyanKali have you checked out MMM-iFrameReload??

  • Thank you so much, that was exactly what I was looking for!
    I can’t believe I did not find it with by searching, I thought I checked all the modules and forums…

    Someone added the possibility to get rid of the scrolling bars in the iframe module. I just copied the code from the iframe module and it works in the iframe reload module, too.

    I don´t want to take credit for it since I just copied it, but if it helps someone else, here is what I did:
    I added “iframe.scrolling = this.config.scrolling;” in the module file, there:

    // Override dom generator.
    getDom: function() {
    var iframe = document.createElement(“IFRAME”); = “border:0”
    iframe.width = this.config.width;
    iframe.height = this.config.height;
    iframe.scrolling = this.config.scrolling;
    iframe.src = this.config.url;
    return iframe;

    After that, you can set “scrolling:“no”,” in the within the module in the config file.

    Thanks again!

  • …me again. Unfortunately, iframe reload did not work. There seems to be an known issue with refreshing pages but I tried the suggested fixes and nothing worked:

    The author of the module does not answer me, maybe I can get some help here? When you click on the link you see my post where I describe what I already tried.

  • Did you ever resolve this? I’m running into the same issue.

  • Unfortunately no. I am still looking for a solution. And I´m still hoping somebody might help with this issue.

  • @CyanKali I’m not sure why the developer didn’t update the git pull for this one.

    I ran into every issue you did when trying to implement the “fix.”

    @CyanKali can you try iframe.setAttribute("timestamp", new Date().getTime()); between line 32 and 33 of the js file?

  • @strawberry-3.141 This worked for me. Outstanding. Thank you.

  • Hi straawberry, thank you for your help!
    So, my js file now looks like this:

    	getDom: function() {
    		var iframe = document.createElement("IFRAME"); = "border:0"
    		iframe.width = this.config.width;
    		iframe.height = this.config.height;
    		iframe.scrolling = this.config.scrolling;
    		iframe.src =  this.config.url;
                    iframe.setAttribute("timestamp", new Date().getTime()); =;
    		return iframe;

    is that right?

    And my congif.js now looks like this:

    	module: 'MMM-iFrameReload',
    	position: 'bottom_right', // This can be any of the regions.
    		config: {
    		// See 'Configuration options' for more information.
    		url: "http://MY_URL",
    		width: "80%", // Optional. Default: 400px
    		height: "400px", // Optional. Default: 800px
    		refreshInterval: 60, //Optional. Default: 3600 = 1 hour
    		animationSpeed: 4000,

    Is that right?

    The stream is working right now, but I don´t see any refresh animation. I will have to wait until tomorrow to see if it reloads because most of the times it takes some hours for the stream to freeze.
