DSMR feature request: provide current power consumption


#1

It would be nice if the component not only provided meter readings but also actual consumption.
So instead of a steadily increasing kWh reading show W consumed since the last reading. I think the DSMR resolution is 10s, So it would be the number of watts consumed since the last reading (or some other time-interval.)
It would make the component more useful to monitor power usage in the house.
