ProfitOrLossReporter and creating reports for battery

[tnlrgn2]

Hi;

Reporting has nice tutorials which adds a process and creates different costs and reports ProfitOrLoss.

I wonder if reporter can also create a report for profit or loss for a battery (which can charge and discharge).
I have tried to create a report for the battery I created with Tutorial I but always got 0 euros at Breakable report even thought system says:
flexmeasures add report --source 4 --parameters breakable-parameters.json --start-offset DB,-1D --end-offset DB,2D

Report scope:
start: 2024-06-09 00:00:00+02:00
end: 2024-06-12 00:00:00+02:00
Reporter ProfitOrLossReporter fetched successfully from the database.
Report computation is running...
Report computation done for sensor costs (Breakable).

Your question is not related to the timely-beliefs package, but to flexmeasures. Unfortunately, I cannot transfer this discussion because these two packages live under different organisations (even though our company is maintaining both). Please repost here.
