Charging data for a wall connector

Hi, I have a wall connector installed in my home and I have a need to understand how much kW was drawn in a certain month to be able to split the cost of the bill. During setup of wall connector in the app, there is an option to set utility rate plan where one can define peak and off peak rates, which is exactly what I need since I sometimes charge during peak hours as well. However, how can one see, at the end of the month, how much power was drawn peak and off-peak, so that I can get exact amount of money I need to pay for the Tesla charging? The only thing I see is how much energy (in kW) was drawn cumulatively for a given period, but no data is shown how much was drawn in peak of off-peak hours. There is also no report of any kind where I could see the actual cost of energy drawn. What is the purpose of entering my utility rate plan and cost per kw, if nowhere in the app this data is utilized to give me any meaningful info? The only thing I see is that I can download a report in a raw format, then I have to import in excel, and calculate on my own, but this is time consuming and impractical. Am I doing something wrong?
