Display-Feed Card by @appdevelopmentandsuch

Context

• Display-Feed-Card requires a carefully constructed entity with a very specific format from your Home Assistant instance to display feed entries on your dashboard, otherwise it will not work as expected.
• The entity you choose must have an attribute called values, which must be an array of objects in the form of:

{
    id: "some-unique-string" ,
    name: "My Sweet Project" ,
    creator: "John Doe" ,
    image: "some-image-to-project" ,
    url: "some-link-to-project" ,
    favico: "some-image-to-original-site" ,
}

or i.e.

attributes: {
    values: [
        {
            id: "some-unique-string" ,
            name: "My Sweet Project" ,
            creator: "John Doe" ,
            image: "some-image-to-project" ,
            url: "some-link-to-project" ,
            favico: "some-image-to-original-site" ,
        },
        {
            id: "another-unique-string" ,
            name: "My Awesome Project" ,
            creator: "Jane Doe" ,
            image: "another-image-to-project" ,
            url: "another-link-to-project" ,
            favico: "another-image-to-original-site" ,
        }
    ]
}

• The best way I've discovered to do this so far is by using the Home Assistant Node Red add-on to facilitate the creation of the entity for the display-feed-card. I've attached a template below as a starting point for anyone interested in creating their own custom feed.
• At the end of the day, as long as you have an entity in your Home Assistant that matches the above template, you should have a feed going.

Setup

1. Go to the display-feed-card release page, download display-feed-card.js, display-feed-card-[some_hash].js, and editor-[another_hash].js and upload them to <config>/www/ on your Home Assistant instance.
2. In your Home Assistant instance, go to Configuration -> Dashboards -> Resources and add the following resource: /local/display-feed-card.js
3. Restart your Home Assistant Server.
4. Go to a Dashboard and add a Display-Feed Card.
5. Set the required information and enjoy!

Node Red Example

NOTE

To use the Thingiverse API you must provide your own token, otherwise the Thingiverse section of the flow will not work. If you are unable to provide your own token, remove the link between the Map Thingiverse Output and Join Outputs, additionally modifying the Join Outputs node by setting After a number of message parts to 1, otherwise the flow will never finish.
