Energy dashboard features

I’d like to see some updates to the energy dashboard

The ability to set a Standing Charge ie. my energy provider charges me a Standing Charge per day regardless of electricity used. This Standing Charge should be added to the total cost info on the energy dashboard.

Add cost to the actual graph hover overs. At the moment we get energy consumed etc.

The ability to group/view by group both the graph detail and the individual devices.

Add total cost to the individual devices chart.

Expose the data the energy dashboard uses to generate its graphs.

Would be nice. Right now I can not see the cost by hours, the minimal unit is a day.
