Battery state card displays battery levels from sensors connected to Home Assistant. It allows users to visualize battery levels using a customizable card in Lovelace and provides various options for configuring the appearance and behavior of the card. It was created to add features and address issues with an existing similar card.
The card offers a highly configurable display of battery levels, including customizable colors, sorting options, and a detailed configuration interface. It handles recent changes and updates to user configurations gracefully, maintaining layout and functionality across Home Assistant updates. The card offers both entity and group support to facilitate display of many batteries.
