Just like the energy dashboard calculates cost when a tariff or tariff entity is entered it would be really nice if utility meters could do the same.
My use case is that I have hourly rate for electricity (different for buying and selling) and I would like to calculate my savings from using solar energy and selling solar energy. But since both of these are dependent on a hourly rate it is difficult using the current utility meter.
Proposed solution:
If the utility meter had an option to add a tariff or an tariff entity (just like the energy dashboard) it would be very easy to calculate the savings from using solar energy.
