I've noticed (possibly since updating to 2025.5.1) that my calculated power usage ('Home') doesn't show any value.
Selecting the monthly overview doesn't show any either, and selecting older months doesn't either.
Since a couple of years I've been exporting this data to google sheets, and I do see changes in the meter reading (p1).
Does anybody recognize this issue? and ofcourse: does anyone have a solution ? 🙂
tnx

How do you have 7kWh of solar produced, and exported 20kWh?

hahaha, I knew that would raise questions. I have 2 setups. One is monitored by a ESP sticky, but the other one isn't (No USB port 😦 ). So the 7kw is produced by one setup, and the rest by the other

Well it raises questions because it directly affects the calculation.
The home consumption is inferred by a calculation using those other variables.
If you have bad data feeding the equation, then you will have unexplained results.
There were some changes in the calculations in this last release, though I'm not sure how you would have got good data from the previous set of calculations either.

The home ...
Well, it's been fine for the better part of 2 years, so I don't see that correlation.
ALthough, as you say, if there are changes to the calculation, that could explain it
As far as I know, the usage 'home' is based on a calculation of Usage/Production taken from P1 data.
If I remove the Solar addition, I still get the same results:

If you're exporting more than you've produced it won't add up right.
potent pebble
Consumption cannot be negative
modern hull
If you're exporting more than you've produced it won't add up right.
true true, but that's nto the case here
potent pebble
While there can be negative production this isn't possible for consumption on the right
Instead of showing -22kwh it's 0
The only way to properly resolve this is to fix your sensors
modern hull
My sensors?
what could be wrong with my sensors, when this has worked properly for almost 2 years?
The data comes from P1
Also: The data exported to Sheets is correct, so there is consumption
potent pebble
The data clearly is not logically correct
You are producing energy from an untracked source
modern hull
The calculation is based on P1 data, so the source would be irrelevant.
potent pebble
It isn't for that graph
modern hull
hmm ok
potent pebble
Neither is it for the consumption
Like imagine you producing solar energy and using it without exporting it to the grid
That would also be untracked
modern hull
ok fair point
potent pebble
The graph can only guess so much which is why it's not what you expect. There was some issue a while back where energy exported from batteries would also throw off the balance, not sure if that was able to be resolved
(A while back as in probably years)
modern hull
ok sure. But again: it worked fine for a long time (I've been able to make some comparison with the data from the power company).
So I wouldn't know where to start to 'fix' things, as I've changed nothing (other then installing updates)
potent pebble
unless the reporting of your data changed the visuals didnt really get more wrong than they were before
like the offset in grid return and production would always have lead to it displaying wrong stuff
modern hull
like the offset in grid return and production would always have lead to it displ...
Hmm. yeah I would imagine so.
Yet I've compared some data to what I got from my power supplier (monthly overviews of usage and return) and those numbers check out. (compared to the numbers sent to Google sheets daily)
Im starting to doubt as to what I used to see in the 'home' figure. Was that Usage of the grid, or Usage of grid+usage of my own panels.
Im not sure anymore :S
😕
So anyway, thanks for your input. I think I'll try setting everything up anew, and see what happens
You too Karwosts
potent pebble
it probably just needs better tracking for your solar input. if the measurement provided from the inverters is unavailable, maybe something like a shelly clamp could measure it good enough
modern hull
Yeah. i have two Growatt inverters. The 'old' one doesn't have a USB port, so i can't use the ESPhome config for that.
The newer one does, and it reports nicely (the numbers from the old one are taken from the Growatt site)
I"m not familiair with Shelly clamp, but I'll look into that.
