Many strings such as the WS2812 are individually addressable, yet the support for RGB LEDs in homeassistant (and esphome) is to treat the entire string as a single color. I am currently using some homebrew code on nodemcu and I really enjoy defining patterns of color. For each stage of the day I have, rather than a different color, a different pattern. On average about 2 to 5 pixels in length that repeat for the length of the string.
I’d like to see a pattern editor in homeassistant and support to applying a pattern to RGB light strings that are individually addressable.
