 If a \l{StateType} has the property \e writable the \l{DeviceManager} will create automatically an \l{ActionType} for this state, which will also have exactly one \l{Param} with the same properties like the \l{StateType}. The created \l{ActionType} has the same uuid (\l{ActionTypeId}) like the \l{StateType} uuid and will be named "set <stateName>".
