How to use the pyvera.VeraCurtain function in pyvera

def test_curtain(vera_controller_data: VeraControllerData) -> None:
    """Test function."""
    controller = vera_controller_data.controller
    device = cast(VeraCurtain, controller.get_device_by_id(DEVICE_CURTAIN_ID))
    controller.register(device, lambda device: None)

    assert device.is_open(refresh=True) is False
    assert device.get_level(refresh=True) == 0

    device.open()
    assert device.is_open() is True
    assert device.get_level() == 100

    device.close()
    assert device.is_open() is False
    assert device.get_level() == 0

    device.set_level(50)
    update_device(vera_controller_data, DEVICE_CURTAIN_ID, "level", 55)
    device.stop()
