The KIT's RoofKIT project focuses on increasing housing density by adding sustainable extensions to existing buildings. The extension includes, among other things, a solar thermal field, several earth collectors for heat generation, a heat pump, and several pumps and valves for hot water control. All devices communicate with each other via MQTT.

The devices mentioned were connected using a Python application so that the heat pump, depending on hot water demand and defined thresholds, either draws heat from solar thermal energy or from the earth collectors.

Additionally, the client was supported in connecting one of their devices via Modbus to MQTT.

The application is delivered as a (Docker) container and operated via ArgoCD in a Kubernetes cluster.

Platomo GmbH develops products in the field of automation and data acquisition in mobility planning. For this purpose, they developed the central server OTCloud, which communicates with smaller services. Both OTCloud and its associated services were successfully containerized using Docker. Subsequently, a central user management system was implemented to regulate access to OTCloud. This involved creating a rights and role concept and securing the corresponding endpoints in the code. The existing user interface in NiceGUI was extended to allow for convenient user management.

The IAI (Institute for Automation and Applied Informatics) has numerous research projects that generate diverse data, which ends up in different systems. This data is not always uniformly structured or complete. A Grafana plugin is being developed to enable the consolidation of data from different sources, providing users with uniform access to all data. For this purpose, an HTTP interface of an existing Java system is extended and integrated in the background, and connected with data from an InfluxDB. The plugin can be dynamically configured in Grafana settings and then used as a data source in panels. When querying data, all possibilities are displayed to the users, along with various filtering functions. Additionally, certain data query settings are possible, such as the size of the aggregation period or the inclusion of thresholds.
