  Internet of Things systems design and development suffers from heterogeneity
in different aspects. The component behaviors also change due to events being
internal or external and the system needs to take action subsequently. In this
paper, we demo the event-based modeling capabilities of the CHESSIoT tool on a
smart parking application. Different components was been decomposed with
functional and behavioral specifications following the component-based
approach. In the end, we have given a brief description of the future work.
