In the context of making shipping more environ-mentally friendly this paper provides a first concept for setting up a cost-effective overall system letting various subsystems and devices cooperate automatically. In the implementation a Flettner rotor or Torqeedo motor gets controlled by a Raspberry Pi 4B sending and receiving data via MQTT. The data of various subsystems is stored efficiently in a database for later optimisation purposes. The database is also implemented with a Raspberry Pi 4B. The concept of collecting data can also be interesting for similar projects.
