Hi @Gruijter , I switched to v9. I was looking for a capability which states the costs of the battery today. This helps to see in what way the battery costs money or not. So: - cost should be raised whenever the battery is charging (tarif = export whenever the battery is charged with solar power of tarif = import whenever the battery is charged with net-power - cost should be lowered whenever the battery is discharging (tarif = import whenever the power is used by our home and tarif = export whenever the power is delivered to the grid I couldn’t find this. Is this in the current version (maybe I didn’t look at the right place)? If not, do you also see the added value of this and can you put it on the roadmap? ---

so if I understand it correctly, Geld deze dag is the revenue/cost of (dis)charging the battery where a negative value means revenue and a positive value means cost?! That whould be exactly what I need but I couldn’t figure this out by looking at the insight-graphs so thank you for you help. ---
