Device power usage on the energy dashboard


I’ve added smartmeter for pool and integrated it to HA to monitor consumption of it. Can someone please explain me why the consumption on the energy dash looks like this, in first hours with plus, in the second with minus?

Energy is supposed to be a continually increasing value.

Your sensor appears to be a power sensor (instantaneous consumption), not an energy sensor (cumulative consumption). The units seem incorrect as well (should be kW, not kWh?)

In case I had sensor in kW, it couldn’t be selected in the energy dashboard. Regaring the cumulative consumption, you were right. I have updated it.

Now it show little bit better results, but still negative values are shown. The question would be whether our filtration and heatpump generates electricity?! :smiley:
