Energy dashboard for individuals device not working with upstream

[nimbusparis]

Hello,
I’ve configured the energy dashboard with some individual devices and I have 1 upstream device like this:

My downstream devices are configured like this:

But, on the dashboard, it doesn’t work like intended:

Canopus (in blue) device is a big computer that use a lot power, why it is counted for the upstream device (in green)?
And why there is unflowed power with negative value?
What is the problem with this panel?

The problem is likely that the sum of individual devices exceeds the grand total use of the house, or the sum of downstream devices exceeds the upstream one. The Sankey chart should show this more clearly. I personally do not see any indication the the upstream sensor configuration is malfunctioning in my config.

A problem might be is a power sensors was offline for a while, and its use during that time gets counted in the wrong our when it comes back online. I do not see any indication of this in your chart though. But since the use for that hour and is quite high, it might be the case. Note there is not prise informatique in the previous hour. Could it be that sensors is reporting irregularly?

And last but not least: is any of those power sensors a template sensor? It might be missing an availability sensor, causing it to count wrong values when sensors it relies on become unavailable.

It seems that my device Prise informatique doesn’t report Energy regulary:

But Power is reported more often:

Whereas energy for Canpus is reported regulary:

And power too:

I need to check where I can configure the tick of Prise Informatique, for Energy, right?

It is up to the integration to do so. If power is reported regularly, you could consider creating an integral sum helper for it, using left Riemann.
