3. Lukevink’s Floor Plan UI
Source: https://github.com/lukevink/hass-config-lajv
You can find hundreds of different variations of Home Assistant floor plans, but I found this one to be the most functional as well as aesthetically pleasing. Individual rooms change brightness and color based on which lights are currently on and the floorplan dynamically adjusts brightness based on the calculated brightness of the sun. It also comes with a custom vacuuming view (see above).
