Hi David,
welcome to the OpenEMS Community!
OpenEMS is not designed as a software for simulations - but it can to some degree be used accordingly.
@kmaruani1 already pointed you to the “Simulator.App” which we developed a few years ago for this kind of tasks.
- Simulation OpenEMS with my own Data (CSV File) - #6 by kmaruani1
- openems/io.openems.edge.simulator/readme.adoc at develop · OpenEMS/openems · GitHub
The resolution of data (5 minutes) in OpenEMS UI is dynamically calculated based on the display resolution. You can adjust it here → openems/ui/src/app/edge/history/shared.ts at develop · OpenEMS/openems · GitHub
Hope this helps. Keep us posted on your progress - it’s certainly interesting for many other users.
Regards (and happy new year)
Stefan
