    Version 4.1
    Switch or dim lights based on the value of a light sensor.
    Light colors or temperature can be set to a fixed value when inside or outside the measuring range (different values are possible).
    Settings for brightness, color or temperature outside min and max values of the sensor can be set.
    To smoothen out transitions, a time can be set where the light will move from the current to the new brightness.
