devolo smart plug metering problem

Dear Community

I have an issue with the devolo smart metering plug:

It works mostly fine however the metering function delivers utterly unreliable readings:

-Voltage and power are ok (but the update intervall is much slower than the programmed 5sec)

-Current and cos phi are always zero

-Cummulative consumption is completely odd: Occasionally it decreases again(attached pic), meanig I would push power back to the grid - noteably with a resistive heater ;-) But as the instant power readings are never negative I guess I can exclude the impossible.

Does someone see the same thing, or is it just my device? Please let me know, maybe my piece just has a bug and I need to make an return:-(

Thanks

Raffael
