Volkszähler integration: Current Consumption/Average

Is there a way to get the average with timestamp now? I need the acutal consumption. Is the timeperiod from the curent average value documented? I can’t find out, what is the underlying timeperiod.

I want to start washing machine when my solar panels produces more power as the curent consumption. My eletric meter doesn’t count backwards so the actual consumption is the only way to see, wenn the total consumption is negative.
