Can we create a card and instead of connecting to data it would display a website?
That's a great idea. There isn't a card that displays a website, but you can set up a table card to display a link to a website. You can put a subset of HTML commands into a cell value in a table card and it will be rendered and displayed. If you use the <a> tag you can add a link.
Can you add your idea to the Idea Exchange here? The product team watches these ideas very closely when then determine what features will be added to future releases.
Let me know if that helps!
