Following up because it took me a while to figure out.

You use the iCloud album id as a config item.

source: “icloud:”,

The album id is simply the last bit in your iCloud shared album URL. It will look something like this:

https://www.icloud.com/sharedalbum/#nUm83r5N13t+3r5

That’s not a real link, just an example.

Copy everything to the right of the #, basically nUm83r5N13t+3r5.

You must use a shared album and you have to set it to Public Website (anyone with the link can view the photos). That will allow you to generate the link. See: https://support.apple.com/en-us/108314

This is what a basic config will look like.

modules: [
  {
    module: "MMM-Wallpaper",
    position: "fullscreen_below",
    config: { // See "Configuration options" for more information.
      source: "icloud:nUm83r5N13t+3r5",
      slideInterval: 60 * 1000 // Change slides every minute
    }
  }
