Abstract

The present disclosure relates to a method for discovering, identifying, and cataloguing devices on a network, particularly, devices included in a home automation or building control network. In embodiments, a node information table is populated with generic entries representing potentially-discoverable devices on the network. The table is traversed iteratively and potential devices are queried in turn to determine the type and capabilities of each potential device in the network. Device responses stored in the node information table, replacing generic entries with updated entries representative of actual network devices. Additionally, device responses may be used as a basis for subsequent queries to network devices. After device queries are completed, any remaining generic node information table entries are removed from the table, thereby only entries corresponding to positively-identified network devices remain in the table.
