Energy-panel savings follow up for self-used solar power

Feature Requests

Hello!

I really like the energy-panel. It tracks my use very nicely. I do however feel It can be improved.

What we have is:
Solar produce tracking
(Imported Energy) * (Energy purchase price) tracking
(Exported Energy) * (Energy selling price) tracking

What we, in my opinion, lack:
There is no separate COST tracking of what portion of the solar power produce is consumed by the actual household.

Reason for needing this type of follow up is it gives us better data on the return of investment of our solar power installations!
(Used solar power) * (Energy purchase price) = “savings” income (not having to purchase this power)
(Sold solar power) * (Energy sell price) = “selling” income

Savings + selling = total return of solar power

Basically

sun_consumed = sun_produced if power_export = 0 else sun_produced - power_export

And this is then tracked against a cash/kWh sensor/static value as the other data sources.

I have created a sensor of sorts myself but I would love to see it somehow better integrated in the energy tab. I’m still evaluating the sensor I created to see if it works as I have imagined it.

Hey, did you every find a work around for this ?

Hi, I created my own sensor just to have it run in the background but its not visible on the energy dashboard. It’s atleast collecting data

if it helps heres my code
copy and adapt

Thaksiwill look to see how i can adapt
