MMM-BackgroundSlideshow just shows black screen

  • To start, I just copy/pasted the code directly from the page. I have checked and I have the sample images in the folder. Any ideas what I’m doing wrong?

    var config = {
    	address: "localhost", // Address to listen on, can be:
    	                      // - "localhost", "", "::1" to listen on loopback interface
    	                      // - another specific IPv4/6 to listen on a specific interface
    	                      // - "", "", "::" to listen on any interface
    	                      // Default, when address config is left out, is "localhost"
    	port: 8080,
    	ipWhitelist: ["", "::ffff:", "::1"], // Set [] to allow all IP addresses
    	                                                       // or add a specific IPv4 of :
    	                                                       // ["", "::ffff:", "::1", "::ffff:"],
    	                                                       // or IPv4 range of --> use CIDR format :
    	                                                       // ["", "::ffff:", "::1", "::ffff:"],
    	language: "en",
    	timeFormat: 24,
    	units: "metric",
    	// serverOnly:  true/false/"local" ,
    			     // local for armv6l processors, default 
    			     //   starts serveronly and then starts chrome browser
    			     // false, default for all  NON-armv6l devices
    			     // true, force serveronly mode, because you want to.. no UI on this device
    	modules: [
    			module: 'MMM-BackgroundSlideshow',
    			position: 'fullscreen-below',
    			config: {
    				imagePaths: ['modules/MMM-BackgroundSlideshow/exampleImages/'],
    				transitionImages: true,
    				slideshowSpeed: 1000, // 1000 is 10 seconds
    				randomizeImageOrder: true

  • @CliffordW said in MMM-BackgroundSlideshow just shows black screen:


    did u do the npm install in the module folder? it has required dependencies…

    usually black screen means something missing

  • I thought I had, but I did it again. Does the message mean something is ‘wrong’?

  • @CliffordW no. That’s ok.

    If you do, npm start dev
    Select the console tab and scroll up to see any errors

    Do u see anything in red?

  • @sdetweil Considering how early on I am, I’m just going to wipe it clean and start again. Thanks for your help, I’ll be back to let you know either way.

  • @sdetweil As I suspected. I rebuilt it, and it’s working now. Obviously some kind of newbie error. Thanks again!

  • @CliffordW glad u got it working!!
