OK - thanks for the reply anyway!

@veldrovive
Thanks again for implementing the current page as “dynamic” class. If I get it right, you had to code procedures to add and remove the page class when switching pages.

Ok, the development branch now has support for the new class name changes. When a module is shown on a page, it will be given the class page_{Current Page} and then the class will be removed when the module is hidden.

Would it be possible to make these procedures accessible via notifications? I am still looking for a way to add and remove classes based on external triggers. A scheme could be like this:

Notification: "MMM_Page-Selector_Update_Class"
Payload: {"add":["Module_1_Name:ClassA_to_add", "Module_2_Name:ClassB_to_add"], "remove":["Module_3_Name:ClassC_to_remove", "Module_4_Name:ClassD_to_remove"]}

Dear @agp42,
I am finally getting back at my mirror and get some time to incorporate your updated module. Thanks again for making dynamic URLs possible!

Would you mind changing this.urlToDisplay = payload.url; to this.urlToDisplay = payload; in your code? Thus, one could send a plain url as payload without the need to process it to be in the format{"url":"http://..."}.
This would make things easier and as the payload will only contain a URL if the notification is iFrame_Ping_URL, this should not cause any problems with other possible content.

Fantastic news!! Thanks a lot!
Will you be keeping the “temporary fix” as additional option to visualize the moon? It worked well and has a quality of its own. Maybe it would be possible to rotate it according to the users location and time.

Dear AgP42,

thank you so much for considering this and spending the time to make it happen. I am traveling at the moment but am looking forward to testing it when I get back home.

Have a nice weekend!

Dear all,
would it be possible to have this module hidden until a weather module (e.g. MMM-DarkSkyForecast broadcasts a DARK_SKY_FORECAST_WEATHER_UPDATE) broadcasts a weather update that contains a snow forecast for today? That would be really useful

@AgP42 Thanks for your reply and happy new year!
I using MMM-Remote-Control to inject notifications from my home automation system (FHEM), as it knows all the other relevant states in the house (user-presence, lighting situation, etc.).

Maybe your module could listen to "iFrame_Ping_URL" notifications and take the "URL" from the payload and use it until a new one is provided or until a restart, in which case it would revert back to the standard URL from the setup?

This way, it would not change its behavior presented to its current users and just gain an option to change the preconfigured URL on the fly.

Dear @agp42,

unfortunately, a playlist does not help for my use case:
I found a 90 min 4K Video Collection from the ISS and want use a defined / selected / random 35 minute section to fill in for the time when the ISS is in the dark.
Currently, I am circumventing it by having multiple copies of the “Night”-page with MMM-Page-Selector and defining different instances of MMM-iFrame-Ping for each page. Each of these instances get a defined URL and I call the pages via notifications, depending on the daylight-status of the ISS.
Having a little more flexibility in the module would make this a lot easier and more dynamic.

Maybe it could be possible to pass on an URL via a notification?

Dear @Veldrovive,
oh - I have to run and hide somewhere. I did forget to clone the development branch when setting up the Mac Mini. Sorry for bothering you with this

As always, if you do things right, they work

You said you it would be a quick change to update the class list to contain the current page. If you have time to add this, it would help me a lot!

Dear @Veldrovive,
I am trying to use an old MacMini to host a mirror, as I would like play BluRays and Amazon Prime Videos on my mirror as well. Everything works fine - except for the option to save the current page.
Frist, I thought this might be a permission issue - but even setting the MagicMirror folder and all its contents recursively to “chmod 777” did not solve it. The mirror always goes back to the standard page and not the current page. Setting “persistentPages” to true does not have any effect.
As you know how you store and restore the “current page” - do you have any idea how to get this going again?
Thanks a lot for your help!
