The ability to change the color of the tile based on the reported temperature value is now available. You can find more details in the release thread here:
Icons and Colors based on States + Window Shades
We’ve noted the requests around setting tile color based on other attributes (eg. Humidity, Lux, CO2, Power, etc) and are working on extending the new ‘State Mapping’ feature that’s used in the Temperature tile to work in the Hero Attribute tile.
