class IotLightStrip(IotBulb):
    """Representation of a TP-Link Smart light strip.

    Light strips work similarly to bulbs, but use a different service for controlling,
    and expose some extra information (such as length and active effect).
    This class extends :class:`SmartBulb` interface.

    Examples:
        >>> import asyncio
        >>> strip = IotLightStrip("127.0.0.1")
        >>> asyncio.run(strip.update())
        >>> print(strip.alias)
        Bedroom Lightstrip

        Getting the length of the strip:

        >>> strip.length
        16

        Currently active effect:

        >>> strip.effect
        {'brightness': 100, 'custom': 0, 'enable': 0,
        'id': 'bCTItKETDFfrKANolgldxfgOakaarARs', 'name': 'Flicker'}

    .. note::
        The device supports some features that are not currently implemented,
        feel free to find out how to control them and create a PR!


    See :class:`SmartBulb` for more examples.
