A system for including a set of software components and an application programming interface for the logical networked representation and implementation of a system of smart devices within a home or small office environment. The software components include a control object component and a user interface component. The control object is a software object capable that carries out communication, accepts and issues control messages. The control object allows a user to remotely control or query a physical device for which the specific control object has responsibility and for maintaining logical and physical connections and control of the device. The user interface supplies a coherent and transparent interface across all network media and topologies. The user interface is capable of communicating with any control object that it identifies as being controllable in a given system. The communication may be across a logical network or may be local to a particular device. The user interface takes on the “personality” of the physical device for which the attendant control object carries a logical and physical mapping and control responsibility.

The method as recited in claim 13, said manager object further:sending said list to any new control object that registers with said system;periodically broadcasting said list to all registered control objects; andperforming a synchronization to force all other control objects to synchronize to the said list. 15. The method as recited in claim 13, wherein said list contains an identifier and an address for each registered control object on said system. 16. The method as recited in claim 13, further comprising performing an election if said manager object ceases to function, said election comprising:promoting a second registered control object to said manager object;promoting all other control objects up one position on said list; anddistributing said list to all registered control objects on said system. 17. The method as recited in claim 16, further comprising distributing said list to all registered control objects if any control object other than said manager object ceases to function. 18. In a network comprising a plurality of software controllable devices that communicate over said network, said software controllable devices containing an embedded operating system and a computer-readable storage medium within which information is stored, a system for controlling said software controllable devices, comprising:a plurality of control objects residing in said embedded operating system of respective ones of said software controllable devices, said control objects comprising component object model objects and including logical attributes of said respective ones of said software controllable devices, said control objects further accepting and issuing control messages to and from said respective ones of said software controllable devices, and said control objects being polymorphic such that said control objects are adapted to take on the logical attributes and command and control capabilities of any of said software controllable devices,wherein said control objects register with said system and are assigned an random unique identifier and are active while said respective ones of said software controllable devices are functioning, and wherein said control objects maintain a list of all other registered control objects and their logical attributes andwherein a first registered control object of said plurality of control objects is designated to be a manager object, said manager object performing list management to maintain and administer said list by periodically broadcasting said list to all registered control objects on said system, and wherein said list contains said logical attributes, said random unique identifier and an address of all registered control objects on said system, andwherein any control object in said system can function as said manager object. 19.
