Smart tarrif & giv enery giv different date

I have octopus inteligent and have recently integrated the octopus data into my giv energy cloud. The data doesnt match though! For example on friday octopus showed 9kw of grid energy but giv enerygy showed only 1kw

Birchcottage are you expecing 9kWh of grid energy? If so, I would check the placement of the CT for the inverter as it might not be reading your EV charge.
