* - state: Whether the light should be on/off. Represented as a float for transitions. Used for

* - brightness: The master brightness of the light, applied to all channels. Used for all lights
* with brightness control.
* - color_brightness: The brightness of the color channels of the light. Used for RGB, RGBW and
* RGBWW lights.
* - red, green, blue: The RGB values of the current color. They are normalized, so at least one of
* them is always 1.0.
* - white: The brightness of the white channel of the light. Used for RGBW and RGBWW lights.
* - color_temperature: The color temperature of the white channel in mireds. Used for RGBWW and
* CWWW lights.
*
* state - Whether the light should be on/off. Represented as a float for transitions.
* brightness - The brightness of the light.

* color_temperature - Temperature of the white value, range from 0.0 (cold) to 1.0 (warm)
* For lights with a color interlock (RGB lights and white light cannot be on at the same time), a
* valid state has always either color_brightness or white (or both) set to zero.
