Detailed Description

IO-Homecontrol command IDs, result codes and protocol enumerations.

Command bytes, CMD_ERROR_RESP result codes, wire position/status flags, cryptographic constants, and the manufacturer/originator/ACEI/discovery lookups. These describe what travels on the wire, independent of the frame container (proto_frame.h) and the device model (proto_device_model.h).
