The situation
Room dashboards in Home Assistant tend to turn into a scattered mix of climate readings, lights, devices and warnings. People wanted one compact card per room without hand-building every chip and sensor row.
What I built
Point the card at a Home Assistant area and it finds the room’s entities itself: temperature, humidity, lights, occupancy, and problem indicators like mold or an open alarm. Thresholds, labels, badges, backgrounds and custom styles are all configurable from a visual editor or YAML.
Why I did it this way
Area first
Leaning on Home Assistant’s own area model means the whole setup can be two lines: the card type and the area.
Performance, per card
People put a dozen of these on one dashboard. Later work narrowed the state updates each card listens to, so one light switching doesn’t wake up every room.
What changed
It’s the most-downloaded card in the collection: 7,825 tracked downloads and 228 GitHub stars as of May 2026, and it’s listed in HACS by default. Most of its feature list came from requests by the people using it.
