Oh but you are doing it right. Even though you’ve tried to balance the loads, which in itself is the correct thing to do, you’ll never achieve perfect balance all of the time. There will inevitably be an imbalance most of the time. You must measure the current in both legs. If you -
and your neighbours who are supplied by the same transformer - could always guarantee a balance, your electricity company would be most grateful because they could do away with the neutral conductor and save money! [It won’t happen - ever.] And then you could guarantee both voltages would be the same too, so you wouldn’t have any error from assuming they’re the same when they aren’t. But experience shows there’s little error in that assumption.
There’s nothing technically against a 240 V kettle connected line-line, but I’m prepared to bet there’s a regulation forbidding it.
You have an emonPi? If you go in via your web browser, you’ll find listed under “Setup”, and entry for Emonhub, and there “Edit config”. That takes you into the configuration file for emonhub - emonhub.conf, which you’ll find mentioned very frequently here. It’s in sections, the one you want is
[nodes]
and your emonPi is Node 5

nodename = emonpi

Your scale multipliers are there.
If you want to do it in the process list, you can. Just add “x” with a value “-1” fairly early on in the list. But as I wrote here only minutes ago in another thread, there’s a danger of needing to do it more than once if you re-read the input to process it for another purpose.
I’m not that smart - I’ve just been doing it a long time.
