I have a fairly simple use case where I want to calculate some stuff.
Per day I am consuming a number of kWh electricity for charging my Electric Vehicle (EV). Per kWh I am paying for a given amount in Euro per kWh (0,16EUR per kWh). I would like to have an overview per month (or other variable time selection like per year/per day) that represents the cost EUR as per the time period selected in the grafana time selection (relative or absolute).
Use case is fairly simple. My accountant asks me to prove cost evidence of the charging times and cost of the charging time. This in the same or separate graphs.
how should I accomplish this?
I already have the following:
Cost per kWh is 0,16 EUR
