On Tuesday it was the first properly sunny day in the UK since around October and had a full battery in the evening so decided to export around 7kw, set the schedule up, and forgot about it, it did discharge approx what I estimated and has set FDSOC to 30%, then it had dropped back onto self use which MINSOC inset to 10% and was not drawing from the grid.
Then yesterday was another sunny day, 2 in a row!!!, the same schedule was still active and again it fell back onto self use at set MINSOC and did not draw from the grid.
So something has changed.
Looks like something has changed, yes. It's now behaving more as expected through the V2 web interface - but not through the app (which doesn't have the MinSoc option when setting the time slot) - setting the time slot through the app still switches to full import when FDSoc is reached.
The other thing I've noticed, however, watching the IHD, is the import/export is *really* erratic on Self-Use. It's currently flicking between -900W and +900W, and various values in between.

I only use the app, never the web interface. It’s now working correctly with the settings shown on the app.

Nope - I spoke too soon. Still importing instead of going to Self Use at the end of FDSoc. Looks like it's still currently inconsistent, at best.

Just had a further response, after several back-and-forths:
We sincerely apologise for any inconvenience and appreciate your patience.
Our current system logic is indeed designed so that once the FD SOC is reached, the battery stops discharging during the Force Discharge period (especially if the time block is relatively long).
Thank you very much for your feedback. Our project team is actively working to optimise the platform, so that after reaching FD SOC, the system can automatically return to Self-Use mode, maximising self-consumption and overall efficiency.
We truly appreciate your suggestions and will strive to make this feature available as soon as possible.
Ref my other post on this subject:

When are they going to sort this out as it is inconveniencing a lot of users?
I am discharging from 4pm and constantly looking to check if min-SOC has been met so i can disable my discharge schedule and force self-use mode. Every day!! And we are getting sunnier in the UK so this will affect more users!!
I applied a firmware software update to my KH7, now on Master 1.6 Slave 1.2 Manager 1.58.
I suspect this wont fix a thing.
