ESPHome Adaptive Lighting

Adaptive lighting component for ESPHome. It sets the light color temperature based on the current position of the sun.

If the light color is adjusted manually, the adaptive lighting will be disabled until the light is turned off and on again. The adaptive lighting is also a switch, so it can be enabled or disabled manually, or by automation.

adaptive_lighting:
  - light_id: cw_light

Configuration variables

• id (Optional, ID): Manually specify the ID used for code generation. At least one of id or name must be specified.
• name (Optional, string): The name of the component.
• icon (Optional, icon): Manually specify the icon to use for this component. Used for enable switch in the frontend.
• light_id (Required, ID): The light to control. It must support color temperature.
• cold_white_color_temperature (Optional, float): The color temperature (in mireds or Kelvin) of the cold white channel. This can differ from the configuration of the light, but it still must be within the supported range.
• warm_white_color_temperature (Optional, float): The color temperature (in mireds or Kelvin) of the warm white channel. This can differ from the configuration of the light, but it still must be within the supported range.
• sunrise_elevation (Optional, float): The elevation of the sun at sunrise. Default is nautical (-12 deg).
• sunset_elevation (Optional, float): The elevation of the sun at sunset. Default is nautical (-12 deg).
