Ah I had added it just for completeness. But thanks for the effort!!

Oh, could you please double check if your setup is the same as my diagram above?  
I had drawn that diagram quickly during my short lunch break today, to get some feedback.  
But in my hurry it seems I have drawn it incorrectly ☺  
My setup looks currently like this:

So I would REALLY appreciate if you could double check my drawing with your setup.

I have done it like that, because in our other [discussion](https://discourse.nodered.org/t/3-phase-power-consumption-measurement/68489/163) on Discourse it was adviced to do it that way. Although now I see that in that drawing the pull-up resistor was connected to 5V while mine is connected to 3V3. Perhaps that is my issue?
