Sudden large negative kWh count in solar production after reinstalling solar panel

1

Hi everyone, been really happy with HA.
I physically disconnected my solar installation for 2 weeks as I was traveling.
I connected it again and suddenly I got a large negative spike in my readings.
How can I fix this? I’m using the Pzem 004T V3.

Thanks!!

Forgot to mention I’m running HA 7.6 and Core ver is 2022.3.8

Anyone got any thoughts? It’s screwing up all the metrics and I have no idea how to correct it.
Thanks!

Hi,
I’m stuck with a large negative value from a wrong reading of a pzem-004 module.
Here is the previous thread

Open your Home Assistant instance and show your statistics developer tools.

You can fix it there.

Thanks, but how do I fix it there?

You need to look at month or day view to find the day it occurs on. Then on the statistics page I linked above, on the far right is a ramp looking thing. You find the date/time in there and change the value.
