The third SmartOT project meeting was again a great success. It took place on 21 September 2021 in partial presence; some project partners met in person in Oldenburg, the others joined online. Since the last meeting, the project work made significant progress in all areas. The current interim results were presented in various contributions and illustrated with demonstrators and simulations. Everyone is already looking forward to the next big step by setting up a test system at the Pius-Hospital Oldenburg to evaluate the functionality in different scenarios.
