Cost analysis without export

Is there a way to display cost savings by rate avoidance? I’m in the U.S. and currently cannot export energy to the grid. DESS is doing a good job managing solar power and grid usage to use power from the grid when it’s cheapest. It already knows how much I use and when as well as the cost at any given time from the power company. It would be nice to have that displayed. Something like solar power generated: 20 kWh, rate in use, $0.29/kWh saving $5.80. Battery power used: 18 kWh @ .29/kWh and 8 kWh @ .11/kWh saving $6.10. Batteries charged 25 kWh @ .02/kWh costing $0.50. Total saved : $11.90 - $0.50 =$11.40

Displayable per day/week/month etc..
