Room Summary Card

Room Summary Card is a dashboard card that shows a small summary of a room with a few basic entities. It adds a room overview to a Home Assistant dashboard, covering climate information, device states, and problem indicators. The card displays room temperature, humidity, connected devices, and entity states in a flexible layout. It discovers room entities, sensors, and device counts automatically based on the area configuration. It can be installed through the Marketplace, or through HACS on version 2026.10 and older, or by copying the card file manually.
