Hi,
I have a virtual feed which is my grid connection but filtered with “allow negative” which I call “Grid Feed-in”
I also have a CT on my solar, “PV CT”
I’d like a virtual feed of these two that I’d call “Self Consumption” that is “PV CT” - “Grid Feed-in”
This should theoretically be the amount of power I’ve self-consumed.
But I can’t see how to make the logic in feeds work. I cant take a virtual as a source for another virtual and I need to do the “allow negative” on the Grid CT before I use it in the process.
Basically I’m after the mathematical concept of brackets for virtual feeds.
Or the concept of storing the current value in a variable to use again later.
Is that possible?
I know I could store the calculated values from this point forward but Virtual Feeds would let me see this data point historically.
