class IotPlug(IotDevice):
    r"""Representation of a TP-Link Smart Plug.

    To initialize, you have to await :func:`update()` at least once.
    This will allow accessing the properties using the exposed properties.

    All changes to the device are done using awaitable methods,
    which will not change the cached values,
    but you must await :func:`update()` separately.

    Errors reported by the device are raised as :class:`KasaException`\s,
    and should be handled by the user of the library.

    Examples:
        >>> import asyncio
        >>> plug = IotPlug("127.0.0.1")
        >>> asyncio.run(plug.update())
        >>> plug.alias
        Kitchen

        Setting the LED state:

        >>> asyncio.run(plug.set_led(True))
        >>> asyncio.run(plug.update())
        >>> plug.led
        True

    For more examples, see the :class:`SmartDevice` class.
