Is there a good emonCMS tutorial on how to combine feeds?
I have a 3 phase system, I currently have 3 phase feeds and 3 voltage feeds, one for each phase. I’d like to combine the 3 phases to give me a single power consumption/generation figure.
I’ve seen in the “solar PV” pre defined feed example of power1 plus power2, but I can’t find and info as to how I can make my own feed with for example “power1+power2+power3”.
I have a bit of a weird system in that I have a 3 phase supply and a 2 phase PV generation. so currently I can tell on an individual phase whether I’m exporting or importing but I like a combined 3 phase view.
Are there any other operators available such as minus, divide, multiply etc?
