Top werk! Will try it asap and report back.
Great, will check it out and let you know my experiences.
MariaDB import works perfectly now. 7 years of energy and solar history imported. No idea what I will do with it now though, besides looking at it 
Thanks for your efforts!

Hi,
I have a problem in the Energy Dashboard because Homewizard changed some sensors and now I have the solar energy double from february 2023 till december 2023.
When I delete the old sensor I miss all the history till october 2021.
So that’s why I tried this import option but it didn’t go well and I lost all the data from the kWh meter.
What I did was the following, I created a csv file with the data from October 2021 till 1 feb 2023 coming from homewizard.
This a part of the csv file i created called elec_solar_high_resolution:

Then I followed the steps and find the sensor ID for the kWh meter I want to update with the historical data. Changed ID nr in the script for the correct one in my database for the kWh meter. I changed the correction to 1.0 because both measurements are in kWh. I didn’t know what to do with the cut of new meter and cut of invalid values and I changed both to 1.0.
Then I Imported the csv and processed the script. When I restored the database and restarted Home Assistant I lost all the data for this sensor.
What did I do wrong?
I hope someone can help me with this so I can correct the data.
Thanks!
You should have kept those values at 25 and 1000.
Now everything above 1kWh (per hour) is considered as an invalid value and deleted.
So for cutoff new meter: 25 means, when the sensor is in kWh that everything between 0 and 25 is still considered a new meter when the new meter case has been detected.
Invalid value: 1000 means, when the sensor is in kWh that every value above 1000 kWh (within an interval) is considered an invalid value and will be deleted.
Thanks for your quick response!
With the correct cutoff and invalid value, the current data AND all the history data are now in the Energy Dashboard!!!
Thanks for this great tool and perfect action plan.
