How to extract power usage records from Database?

[Gatsby]

Hey there,

if played with my domoticzs install a couple of month now and it recorded some power usage
I don't want to loose. I know its all in the domoticz.db. I even looked into the db to get familiar with the structure.

Now: How would I get only the recorded data (temperature, power consumption etc.) in case I would do a complete
reinstall of domoticz? My goal is to migrate as little as possible from my current installation.

Greetings
Gatsby
