I am to stupid, please help with import of data

[prawnhitter]

Hello everybody, i am officially too dumb to import stuff.
I installed spook and went to the recorder describes as https://spook.boo/recorder/

But now every input (even the example) are not working.

Now en detail:
I have an photovoltaic system with historical data.
Data.csv

I do have the equivalent sensors (eg Household Energy) -> Coloum D in Data.csv
history.csv

now i want to import these data into that sensor but:
1st im not sure if everything is correct the data from history is in "W" but the data from data is in "kW". do i need to convert it first?

2nd do i need the +02:00 when i put the correct time in?

Now when i press Call Service
i do get the Error "Failed to perform the action recorder.import_statistics. expected a list for dictionary value @ data['stats']. Got None"

Where do i make a mistake?

Greetings Andreas
