I noticed in the past month that my daily energy production doubled in size. The problem is persistent but doesn't show up on a daily basis. I don't have a definite fix but can however fix these weird spikes manually.
I decided to post to show how to correct these spikes when they occur.
Let's say there's a weird spike in the evening which adds 100kWh to my Solis Energy Today kWh.
This would look like this:
The problem is located on a sensor which reports the daily kWh total. In this case it's Solis.
My next step would be to go to the settings menu and look for Development settings > Statistics Tool and look for the sensor which has the problem.
Then it's a search to the right moment on which the error occurs. In this case see:
Now just adjust the incorrect value to the desired one. In my case this is 0. Then just reload the energy dashboard and the error won't show.
