# Treemap Card

> Treemap Card is a dashboard card for Home Assistant. It has 79 GitHub stars and was last updated September 22, 2026.

Treemap Card is a dashboard card that shows Home Assistant entities as a treemap of colored rectangles. Rectangle size reflects each value relative to the others, and color indicates status, which makes it easy to compare sensors, lights, thermostats or other numeric data. Data comes either from entities, with wildcard support and per-entity settings, or from a single entity whose attributes hold a JSON list. Lights are sized by brightness and show their actual color, and climate entities offer computed values such as the offset from target temperature. Climate tiles can also be colored by heating or cooling activity, and sparklines highlight when the HVAC was running. Tap and hold actions, per-tile CSS, number formatting and auto-entities filtering are supported, and it installs through HACS or manually.
