Hi all,
I have a power meter (vendor: ISKRA MT681) that I read out with IR interface from Hichi.
It works fine after the January 2022 update of HA (see screenshot).
I get a reading (via template code I found on Github) showing me instantaneous net consumption (“Nettobezug”) from grid under consideration of my photovoltaic production - this is what I need to charge my vehicle while I have more production than consumption.
However, I would also like to see my instantaneous production (negative active energy) and consumption (positive active energy). I tried with statistics and also riemann integration but to no avail (failures in parsing configuration.yaml).
I only get absolute readings (see screenshot) - could someone point me into the right direction of how to get the present consumption/production from my EDL21 sensors?
It would probably have to be calculated by (reading at time t2 minus reading at time t1)/(t2 minus t1).
It should be ok if the sensor value is aggregated over the last e.g. (t2 minus t1) = 10 to 30 seconds.
