Woldcraft Digital was involved in the technical implementation of an IoT project in the field of heating and energy technology for Wimmer Solutions OG. The goal of the project was to intelligently connect heating systems in order to efficiently collect, process, and utilize operational and sensor data for various applications. Woldcraft Digital primarily supported the project during the implementation phase, contributing technical expertise in both the development of core software components and architectural topics. The main focus was on frontend development using Angular, delivering modern and high-performance user interfaces for managing and visualizing system data. In addition, backend components based on .NET were implemented and integrated into the existing system architecture. PostgreSQL was used as the database solution for storing and processing the data. The result is a scalable IoT platform that enables reliable communication with heating systems and provides a solid foundation for future extensions.
