I see what’s happening now. The problem is one that @TrystanLea will have to sort out.
I looked at the Github link; but I don’t understand Github and it made no sense whatsoever, and the code isn’t in the standard emonCMS. So I can’t offer a patch.
What’s happening is the code doesn’t apply the “addresses” suffix from the configuration in post no. 112 to the node names, with the result that, as pointed out by @m2ts in post 116, both sets of values are written to the same feed, and the second value to arrive (most times it will be address 2 - not always) will overwrite the first.
So I’m afraid only @TrystanLea, as far as I know, will be able to help you. Sorry.
I’ve just noticed this:
That problem might actually be related?
