The OCHPdirect InformProvider meterReading is defined as "The current meter value as displayed on the meter with corresponding timestamp to enable displaying it to the user". Those absolute meter reading might be a privacy issue or in this case more a company trade secret issue. I think it should be up to the CPO to send absolute or relative values, what means to start with a value of "0" at the start of a charging session.
