Thank you @sparkylarks ! I wrote down (please correct me): 1. The UMH is considered "big" and hard to start with (requires VM, does not run on RPI 4) 2. It seems to be not obvious how to integrate the UMH into the companies landscape without scrapping everything else. Maybe this can be mitigated with more examples. 3. We are definitely on the right track with the management console

Where do I put the data? What is my Topic hierarchy. i.e. Where does the ERP data go. When to I put a lot of data in a single payload, when do I use lots of little paylods with one datapoint.
