The more complex the processes, the higher the need for process transparency through high-quality real-time data. The steady improvement of Internet-of-Things technologies, or of the recently phrased cyber physical systems, during the last years ensures this process transparency. Although these technologies are promising, the potential of IoT/CPS technologies is not yet fully applied in practice. One reason is that technology novices have difficulties participating in development processes and consequently prevent case-specific and relevant services from being described. This paper presents an adaptive interface approach to support the development and utilization of IoT solutions. An exemplary solution is presented based on an IoT toolkit with a GUI for configuration, making service development possible without coding skills. Based on experiment observations, design improvements of the GUI are implemented. Furthermore, a more sophisticated design is introduced. This will allow users with different competence levels to improve their interaction with sensor and actuator networks further; consequently, more appropriate solutions can be developed and used.
