A device that monitors one or more sensors in a building and can raise an alert if a sensor detects unexpected activity. Security systems can be armed and disarmed. They can be armed at multiple security levels (for example, Home and Away) and they can report information about certain sensors, such as a sensor that detects motion or an open window.
Given a similar accessible trait set as the function above, returns a subset of those traits that are present in the associated HomeConfig.factoryRegistry union'ed with those already known to the extended sub-class (e.g specific DeviceType that is aware of the set of TraitFactorys specified in its type definition).
