Hi! I'm trying to understand why some of my energy usage is showing up as 'untracked'. I have clamps on every circuit, and some of the smart plugs downstream also report power - they're tagged with an upstream device. I'm also confused by the two "Total consumed" lines. There's no power production, three phases coming in, and the clamps on the individual circuits assume that the three phases have equal voltages.
I'm also looking at the new sankey graphs, and wondering if that would explain some (mis)configurations? The music loft and pyramid that show up without parents on the right are both supposed to have the same upstream, which is missing

there's some error in your measurements, so your devices are reporting more energy in total than the upstream devices see
that's why 'untracked' is showing up as negative

Ah, right. So likely one of the clamps is misreporting, correct?

What's their upstream that's missing?

It's a bit tricky in North America because you get 208V from combining two phases into a circuit, and then you multiply that by √3, and while my config looks correct, that's where I suspect I might be miscalculating
@proper wedge "North Room W Wall Energy"
Which, hmm
Looks like that might be unplugged or unclamped

Do you have 3-phase or split phase?
tough thistle
3-phase

But you can't just sum current of the phases. If using √3 you assume a power factor of 1 which is rarely the case.

Ok, it works a lot better when you don't forget one of the clamps 🙂

Yeah. Looks like that 60 amp breaker should better match wire size.
tough thistle
Yeah no kidding. That one kept me awake the night I realised it was probably way oversized.
It's cleaned up now
It was also a different brand, which is a no-no
But thank you for noticing and warning me!
@harsh trench how do you do it, if not by √3?
harsh trench
You need a device that measures the current, voltage and power per phase. And power can just be summed if needed.
Just calculating the power from voltage x current or using √3 will all assume a power factor of 1. Which nowadays is rarely the case.
