@sdetweil it has debug:true support. Here is the original js cinfig file

Module.register("MMM-WiFiPassword", {  
  defaults: {
	  qrSize: 125,
	  colorDark: "#000",
	  colorLight: "#fff",
	  authType: "WPA", // WEP, WPA, NONE
	  network: "REQUIRED", // Your Network ID
	  password: "REQUIRED", // Your Network Password
	  header: "Local WiFi Details", // Default heading
	  hiddenId: false, // Whether your Network ID is hidden
	  layoutVertical: true, // Whether to display in vertical (true), or horizontal (false) mode. 
	  showNetwork: true, // Display network name
	  showPassword: true, // Display password
	  showAuthType: true, // Dispay authentication type
	  debug: false
  },

I know it reads my network and password right because if i copy paste them after scan to a notebook the text is correct. I even tried to change the scan application but same result. When I choose to connect to the scaned network nothing happens.

@sdetweil In fact I just did and 2 minutes now I have black screen

@sdetweil I don’t think it work. I set debug to true and after restart I did not find any debug log and beside that my network name and my password was shown below the module. I don’t know. Maybe I will try uninstall it and reinstall it and see how it goes. Thank you for your answer though.

Hello everyone. I hope you are all well. I have a problem with the MMM-WiFiPassword module. I installed it but it does not seem to work. When I am scanning the QR code nothing happens. I have also change my password so is does not have any special cahracters as the author recomends but still nothing. I hope someone can help me with this. Here is my config:

 {
      module: 'MMM-WiFiPassword',
      position: "top_center",
        config: {
          //See 'Configuration options' for more information.
          header: "WiFi",
          network: "VODAFONE_7402", 
          password: "***********",
          showNetwork: true, // Display network name
          showPassword: false, // Display password
          showAuthType: false,
        }
    },

Also after playing around with my custom.css for exact positioning I noticed a very big delay on the MM start up. It takes more than 1 minute with black screen and more than 2 minutes to load all modules. I know that probably it has nothing to do with my custom.css but it happened after I changed some things to figure out the desired position of the module. If anyone has any idea what is causing this delay please share it. Thank you in advance.

This is a screenshot of what happened after about half an hour after restarting magic mirror.

I will try this as well but 3 days now the problem does not appear. I haven’t touch anything on my MM and I don’t see the black screen. I will try a sudo apt-get update && sudo apt-get upgrade although. It is always usefull. Thank you.

@sdetweil
I don’t think that this is the problem but I want to test it just in case.

@sdetweil
In my case when the screen goes to sleep everything is hidden, modules, dev console etc. I see only black screen. Is there any possibility that pi “forgets” the setting to disable the screensaver? I will try to go and change this setting and after put it back again to see if anyhting changes.

This is getting too weird. Yesterday I had the MM running in dev mode and after I saw the screensaver I moved the mouse and everything came back as normal and no errors in the console. I don’t know why this happens not all the time and with different characteristics everytime.
