Thanks for your link.I want use the result in app or graph. Thus virtual seems to be ok. But It is not so obvious… and version are newer.
I don"t understand where I should add your code. I’d like to keep the emonCMS solution if possible. I’m surprised that people using emontx don"t have this issue.
We all were newbys once, it’s nothing to be ashamed of, and the best way to learn is to play with the data. You sometimes need to be very inventive when you manipulate the values. When you click an operation, read the text in blue, because that gives a brief description of what the command does.
You didn’t need the Reset to zero and you didn’t need to add emonpi:p1, because that’s automatically there at the top of the list.
So you could have had
1 + input Node emontx3:power1
2 Log to feed emonpi:powerRDC
If you had wanted to log emonpi:p1 separately, and you had done other things first that made the number that’s passed down the list different, then generally you do need a Reset to zero so that you can start again.
