Abstract	The Internet of Things (IoT) is the new rapidly-growing domain that is constantly evolving in terms of infrastructures, integrated solutions, development tools and best practices. The availability of so many devices in the environment, for various purposes and missions, entails a critical control challenge, raising issues related not only to security and safety but also to individualization and adaptation. In fact, the main benefit in everyday life is expected by the wide introduction of software automations that can control and coordinate such devices in ways matching individual people needs, preference and requirements. But the demands for such automations are so customized and fluid that the corresponding digital market is currently either non-existent or very limited. Now, one potential solution to this supply-demand gap is enabling users develop directly their own automations. In this context, the adoption of visual programming gained increased attention as a vehicle to enable composition of individualized automations by non-professional developers. In this thesis, we present a custom toolset, built on top of a recently developed visual programming IDE, which facilitates end-user development, execution and testing of IoT automations. Firstly, an automatic generator is introduced, which produces userinterfaces for smart devices relying on their API specifications. Then, we present a runtime environment for automations that provides advanced monitoring and interaction tools including a device dashboard, a calendar for scheduling automations and a history panel that records and displays device events. Following, we discuss a custom runtime for testing purposes, which offers virtual counterparts of all physical smart devices, so that testing is done locally, in a protected and isolated environment, without requiring operation of the real devices. The latter is possible through our simulator, which enables interactive manipulation of all device properties and operational modes. Additionally, we implemented a time controller (i.e. virtual time) to handle the flow and pace of time during testing, enabling trigger scheduled tasks in a way not interfering with system time. Finally, we outline a case study involving various scenarios of everyday automations.
