Battery Companion Card is a polished dashboard card for Home Assistant that gives you a clear overview of all battery-powered devices in your home.
It shows battery levels, low battery warnings, charging status, hidden devices, and a compact summary panel with useful insights. The card is designed to work inside Drag & Drop Card, so it can be resized, positioned, and styled directly from the dashboard editor.
The outer container stays transparent, while the card itself supports background color changes from the Drag & Drop Card design settings.
