Problem with Charge Settings

For years I have run a program that uses the API to set the charge settings to optimise how much to top up the battery every night. Last night the battery charged to 95% when the API had previously set it to 50%. The portal inverter settings tab shows 95% charge between 00:30 and 05:30 yet the remote log page shows the last change to charge settings was to 50% from 00:30 to 03:30. The previous setting was 95%. Any ideas on why the API shows as successful in both the remote log and my program log yet the inverter worked to the previous settings?

Raised a problem through email with giv and was very surprised to get a response within the hour. Suggestion is there is a problem in the 3020 firmware and they are going to update to a newer level.

locked I think their default response is to update firmware to see if it helps. I once reported a problem that was clearly an issue with the portal itself (accessing the activity log), and was a bit cross to discover they updated inverter and battery firmware as a matter of course.

I guess it's simpler than actually having to think about it.
