I want a flow to update current energy euro/hour by multiplying current energy price by the number of Watt shown bij the energy dongle in the energy tab and on the device icon. I can however nowere find this number in the values I can insert in a variable calculation. I can choose from all numbers be it variables or app readings but nowhere can I find e reading with the name “Energy comsumption” or any other desciption that shows the current value in Watt as mentioned before.

I have

vermogen -606

vermogen (fase 1) -953

vermogen (fase 2) 145

vermogen (fase 3) 13

While the energy dongle reports 450 Watt

Well it seems “vermogen” is the correct value but current value shown next to it is wrong. Or is this number never updated?

You seem to expect real values, but since Pro 2023 only bogus values are shown in the tag selection list. Just ignore those:

BTW “vermogen” is the one you want, but it"s consumed power and produced power, depending on positive or negative values.

Energy consumption = Energy (kWh), not Power (W)

Ah bogus values yes that’s where I went wrong, thanks. To convert watts to kilowatt-hours (kWh), multiply the watts by the number of hours. Since I want to know consumption/cost per hour I multiply by 1. So Wh = W and kWh = W/1000
