Hi Carlos,

Optimization of power allocation:
As we discussed in person, good examples for similar Controllers are:

and

CSV file
The way we usually do it, is:

  • Record data via Timedata.InfluxDB into an InfluxDB database
  • Analyze data using Grafana (https://grafana.com/)
  • Export data from Grafana to CSV
  • Import to OpenEMS

This gives good control about what data we want to use for simulation and in which resolution (e.g. one value per second or one value per 15 minutes).

Otherwise, see also this post for details on how to implement your own Datasource: EMS-Simulation durch Daten aus DB statt CSV-Dateien - #2 by stefan.feilmeier

UI historic view

The Datasource for simulated meters is a different concept than the Timedata provider. I understand, that those can easily get mixed up.

  • Datasource provides a new value on each Cycle for live simulation
  • Timedata provides access to historic data that it was previously recording

Stefan
