#Strange "upstream device" behavior in dashboard.

So I have a North American split phase power system. I have added CTs to the feed lines into my house (not the top of my distribution but can be considered as such for this discussion) and defined my "Total Home" consumption there. I have set it as the upstream for defined devices in my house and I regularly see negative power values (but not all the time) for the Total House usage.
Now the picture does show some negative but what it doesn't show is that this graph can change on reload, sometimes the 0600-0700 bar shows the total home power as negative and sometimes as positive and I'm quite confused about it.
Verified CTs are all turned the correct way and the computational nature of the "untracked" value has me scratching my head.

Negative untracked implies that the children of House Total Power consumed more energy than was reported by House Total Power

So I might be confronted with a recalibration of my CTs then.

Or just learn to accept that you're dealing with imperfect information 😂

I dunno, might trigger me into full blown OCD. 😛

Curious though why you have lots of grey untracked. If House total power was really your whole house consumption, there wouldn't be any untracked energy as it's all tracked by the green?

#

Or do you have more sources

That's why the "not the top of my distribution" comment. My power feed comes into my detached garage and house fed from there. I have a lot of stuff in garage like freezers, most of my IT stack, etc. outside of the house panel.

The dashboard for me is mostly about an educational program for my family to become aware of where power is being used and why we do things like put timers on the espresso machine rather than let it run all day.
