So…
I finally succeeded at placing a 50A CT around the neutral (blue) cable which goes toward the 3rd table.

I also put a 50A CT around the black thread which empowers the Vue (I find a bit silly that the Vue does not report its own consumption directly in the app/graphs).

2 strange results :
– The App is able to give the total consumption of all circuits. But when I click on it the graph is flat zero ! In the CSV exports, this total is not present too.

– The CT around the black thread empowering the Vue detects absolutely nothing.

I see that I didn’t mention it clearly but I’m in Belgium (Europe) so our voltage is 220-240V@50Hz. My meter is in a “main breaker table” and a single phased 40A one. All the cables and breakers feeding the daisy-chained breaker tables are set up for an eventual 3P+N future usage (if I add EV & Solar).

Here’s a picture of my “secondary breaker table” connected to the Vue : power come through a 4x10mm² cable from the 40A meter (main breaker table) towards the top right 300mA Diff-O-Jump which feeds the 3phase breaker and 4x6mm² of the cooktop (only one phase being used for now). The rest of the table is cabled as single phase and split between wet (30mA breaker -> washers & dryers) and  non-wet (oven & fridge/lights) appliances.

The “tertiary beaker table” 4x10mm² feed was tapped directly at the top of the 300mA Diff-O-Jump so it bypasses the “secondary breaker table” to optimize the cable lengths.  But now this is where 200A CTs will never fit… hence my question about using only 50A CTs.

Hi, I’m Oliver.

I was lurking for years at ways to accurately monitor and put concrete numbers behind our household consumptions.
Was interested in Smappee, Sense, Emporia Vue Gen1… and finally got my Vue Gen2 last week.

Being in Belgium (Europe), I’m on single phase 40A – 220V meter for now but will eventually pass on 3P+N when I’ll get my EV and will install solar panels.

I’m still struggling with the installation of my Vue because of the size of our breaker panels. These are waaaaaay smaller than yours (in the US) and there’s no room for the Vue and even not much for the CT’s. Besides that, I’ve also my 3 breaker tables daisy-chained which complicate things a bit further…
