Partial import / catchup

[fysmd]

Hello all!
I'd like to import a recent period of data from teslafi as my DB stopped for a week while I was away on a road trip.
I can ecport form teslafi but I'd like to import this into the teslamate db and leave all previous data intact.

I have daily backups so can roll back so no data overlaps but how can I do the import (safely)?
