Home Assistant custom cards
What a custom card actually is, what HACS does and does not do for you, and how to tell which cards will still work after the next Home Assistant update.
6 packages, all installable through HACS
Mushroom5.2kA coordinated family of compact cards with visual editors. People reach for it for the look, plus its chips and templating.
Bubble Card4.7kA single card type that takes the shape of whatever you point it at, from a light slider to a media player, plus pop-ups that let one dashboard hold a page per room. Most people install it for the look and the pop-ups together.
card-mod1.8kLets you add your own CSS to almost any Home Assistant card, for the changes a card's options and your theme can't make. It adds one card of its own, mod-card. Everything else is styling on cards you already have.
Room and Notification Cards293Two button-card templates by polamoros: a room card with a column of round controls and status badges, and a notification card that stacks alerts on top of each other until you hover. You paste them into your dashboard YAML rather than installing them.
Ultra Card277Ultra Card is a visual dashboard builder for Home Assistant. Rather than adding one card per thing, you add one Ultra Card and build inside it: 94 modules, drag-and-drop rows and columns, and every setting in the editor instead of in YAML.
Compact Power Card161A single card that draws the whole flow of power through a solar house: panels, grid, batteries, the home, and the individual loads underneath. It fits that picture into a card you size yourself, rather than a page of its own.
