Such systems comprise of devices manufactured by various suppliers. Verification is a challenge due to high heterogeneity of composing devices. In this paper, we present initial results of model-based interoperability testing for IoT systems to facilitate automatic test case generation. We utilize messaging model of Constrained Application Protocol so as to deduce complex relations between participating devices. We use Complex-Event Processing (CEP) techniques in order to streamline the verification process after generating proper runtime monitors from sequence diagrams. We demonstrate our solution on a fictitious healthcare system.engrestrictedAccessconferenceObject242606610.1007/978-3-319-93797-7_8Internet of thingsModel-based testingConstrained-application protocolRuntime verificationComplex-event processing2-s2.0-85051081121
