Recharge at home exact charge

Home recharge

In the case of charging at home, I do not immediately get an exact number of kw charged, which in the public columns are highlighted in a standard way. However, at the end of the month, I find myself with a difference of +20% of the kw charged by the operator. I thought it would be useful to implement the possibility of importing from an excel sheet. Where I will have inserted an increase on every single cell (recharge) of + 20%.
It seems to me that there is already an import from Tesla, an identical import from an excel sheet should be implemented.
