Battery charging from the Grid much more than before

Pulled some stats from the API
(ref - https://givenergy.cloud/docs/api/v1#energy-flow-data-POSTinverter--inverter_serial_number--energy-flows)

" Grid to Battery - The amount of energy imported from the grid that has been used to charge the battery"

So what I can see is a massive difference since January actually

I think the method of calculating energy flows was changed Christmas Week.

I charge my battery nightly, so my figures are normally 200kWh to 300kWh per month, so I cannot detect a small change.

Has there been any change in your utility meter readings?

I have eco mode set and wanted the battery to charge only from solar and never from grid. I got a reply from GivEnergy support
"This is because there is currently an issue with the reporting at the minute. We are aware of issues with the presentation of incorrect solar and grid data on Energy graphs on the web portal and app and are actively working on a fix. We are still investigating the issues behind the incorrect energy data and hope to have these resolved soon. We will shortly be reverting to our previous energy data solution while the fix is being fully tested.

Please continue to use the system data, meter data and the power flow graph to monitor the system. For accurate energy usage, please consult your energy provider."

Not sure if that is a perhaps just a standard reply to queries on charting ?? I think its really important for customers to know what usage they are using and hope they can resolve the issues asap.
