A method may be provided for a system having a logic device interfaced between a management controller and a plurality of subsystems, wherein the logic device includes a plurality of purpose-built engines, each purpose-built engine configured to perform single-wire communication with one or more subsystems in accordance with a particular protocol associated with such purpose-built engine and a purpose-built engine group switch interfaced between the plurality of purpose-built engines and a plurality of connectors for communicatively coupling the plurality of subsystems to the logic device. The method may include establishing, with a purpose-built engine group switch, a plurality of communication routes based on one or more switch control signals, wherein each route of the plurality of communication routes is established between a respective purpose-built engine and a respective connector. The method may also include monitoring all possible one-wire communication paths between the purpose-built engines and the subsystems for announcements of protocol types. The method may further include in response to such monitoring, communicating the switch control signals to the purpose-built engine group switch in accordance with supported communications protocols of individual purpose-built engines of the plurality of purpose-built engines.
