        It is possible that the calls are made for multiple lights at once,
        which in turn might be in different switches or no switches at all.
        If there are lights that are not all in a single switch, we need to
        make multiple calls to `light.turn_on` with the correct entity IDs.
        One of these calls can be intercepted and adapted, the others need to
        be adapted by calling `_adapt_light` with the correct entity IDs or
        by calling `light.turn_on` directly.

        We create a mapping from switch to entity IDs and keep a list
        of skipped lights which are lights in no switches or in switches that
        are off or lights that are already on.

        If there is only one switch and 0 skipped lights, we just intercept the
        call directly.

        If there are multiple switches and skipped lights, we can adapt the call
        for one of the switches to include only the lights in that switch and
