Microspikes every 10 Minutes

Hi Markus,

I once in a while see spikes in my Home Assistant timeline. I've monitored the debug log and can see the spike there as well:

At 2024-11-12T16:58:32.387469025Z the SOC out of the sudden rises from 10 % to 14 %. then returns to 10. Do you see anything similiar?

Also sometimes there as spikes in the opposite direction also happening:

At 2024-11-12T16:45:09.139067652Z drops from 11 to 9, returns the next poll to 11 again.

Any idea, where this is coming from?

Hi Ralph,
well I am using this addon/integration just a very short time.
But I do not see any spikes (or dips) in the battery percentage.
So, I guess, these are real values being reported by your battery.
And they might be a sign of the battery is not working properly.
Take care
Frank

Thanks Frank. Do you also use multiple batteries in a stack?

Hi Ralph, Yes, I am using two stacked Noah 2000 batteries. This is how it looks like here:  Take care Frank

Interesting finding:
I only have these spikes on any discharge. When power goes into the Noah's, this does not encounter.

Thanks
Ralph
