Hello everyone,
I want to show the total energy cost, which is already displayed in the energy panel, on a custom card.
I want to put this value into a card like it is displayed here.
How can I do it?
The energy dashboard does not expose any entities. You will have make your own.
I have this desire too but I’m struggling to make a sensor that sums it for the month.
Did you have any luck?
create a TEMPLATE with the calculation?
or a HELPER with the integral function?
I created a sensor doing the calculation but the values are not the same that in the energy dashboard 
I have done something similar with my gas meter monitoring…
See my most recent update on this thread… there is an explanation of what I did and some yaml that I created.
I hope this helps! 
Cheers,
Mike.
Hi David,
I have done something similar and noticed a small difference between the ‘official’ HA Energy dashboard costs, and my own, custom dashboard costs. It is only a few pence out over the course of a day, so I’m not that bothered about it.
I can’t explain why, as both the Official Dashboard and my custom dashboard are using the same sensor information. 
Maybe a maths rounding error at a guess. 
Cheers,
Mike.
I wish there was a simple way for this. Where do I vote for the “Total Grid Cost” entity to be added?
