Hi comunity,
I am quite new with Home Assistant and hope to find some help for the following little project (on wich I still do not have an approach of how to implement this, at all)
I would like to permanently store the amount of power, our E-car was charged with in a kind of variable. I then would like to be able to query this variable for a specific day (calendar view?!) to figure, how much power was charged to the car…
In a further process, I would like the last stored value to be added to an excel sheet, to track, the charging processes of the EV…
Any ideas, on how to start on that? What do I need? A template? A helper? Thanks
Holger
