I am downloading the data from https://vrm-api-docs.victronenergy.com/#/operations/installations/idSite/data-download to make a summary display which is similar to the sunny portal.
All the info is available in 15 minute chunks from this api.
However, the 1215 data does seem to arrive for 10 minutes or so. Are the same datapoints on the filesystem of the Cerbo GX? Or is it a case that the calculations to create them are done in the cloud? If I can get better resolution than 15 minutes that would be useful.
