Device Card for Home Assistant

Everything attached to one device, on one card, sorted into controls, sensors, configuration and diagnostics.

Three device cards, each listing a device’s configuration, sensors and diagnostics in sections

The situation

Home Assistant’s built-in cards don’t give an organized, per-device view. People with dozens of integrations wanted one card that shows everything a device exposes, grouped sensibly.

What I built

Two cards in one package. The device card shows a single device’s entities in expandable sections. The integration card rolls up every device from one integration, like Z-Wave or Hue, into a grid of device cards. Both have visual editors, filtering, and translations in four languages.

What changed

2,362 tracked downloads and 120 GitHub stars as of May 2026, listed in HACS by default.
