The IoT test bench represents a partial section of a room air conditioning system on a laboratory scale, whereby the volume of air conveyed can be varied and the air volume flow can be conditioned with heat. The research focus here is the investigation of the underlying automation system(s), as three different control concepts are available: One local system and two systems connected to the FIWARE cloud. For the two cloud systems, all communication with a FIWARE instance at RWTH Aachen University proceeds under consideration of encryption, authentication and authorization.
