@coneyrabbit there is now in ESPHome 1.14 (updated this gist). BEWARE that brightness in Home Assistant controls the RGBs and White Value controls the White brightness.. if you have both values at 100% both sets of LEDS will run and overheat chip causing random restarts within 10min.

If you put color_interlock: true in the rgbw platform attributes it will force the white off for colors and turn the colors off when going back to white preventing both being on and overheating. Also when you click white or tell google to set the light to bright white it goes back to white. Saying just white they still turn to a dim white cause it doesn't turn the white value back up unless you say bright white. Pretty much fixes this is sure you are taking about here

Thanks @jokesters, I'll try it out tonight... Didn't get a notification of your mention/response so I'm just seeing this.
