    \title WeMo

    \ingroup plugins
    \ingroup network

    This plugin allows to find and controll devices from WeMo, the
    \l{http://www.belkin.com/de/PRODUKTE/home-automation/c/wemo-home-automation/}{Belkin}
    home automation system.

    \chapter Plugin properties
    Following JSON file contains the definition and the description of all available \l{DeviceClass}{DeviceClasses}
    and \l{Vendor}{Vendors} of this \l{DevicePlugin}.

    Each \l{DeviceClass} has a list of \l{ParamType}{paramTypes}, \l{ActionType}{actionTypes}, \l{StateType}{stateTypes}
    and \l{EventType}{eventTypes}. The \l{DeviceClass::CreateMethod}{createMethods} parameter describes how the \l{Device}
    will be created in the system. A device can have more than one \l{DeviceClass::CreateMethod}{CreateMethod}.
    The \l{DeviceClass::SetupMethod}{setupMethod} describes the setup method of the \l{Device}.
    The detailed implementation of each \l{DeviceClass} can be found in the source code.
