admin Been away for a few days but I think I saw similar behaviour on Saturday 5th July.
I have pre-selected charge slots (anything below 13p) some of which I changed to be export slots. Only the ones where the battery SOC had reached 100% actually worked for export. It looks to me like the pre-selected charge slots remained selected even during the export slots. Both command sets were sent to the inverter which, on my GE AC3.0, meant that the charge took precedence over the export (the log has wrapped now but I did see this on Saturday when I looked). But when the SOC reaches 100% the charge slot is skipped and the export works as it should.
So I think charge and export can still be set for the same slot. I may have set my export slots before the 4.35pm repopulate then at 4.35pm the server added back all the charge slots - even the ones that had been selected as export slots.
I am away again for a few days and can't respond to the forum if it occurs again.
In the picture below there should have been some export slots between 0am and 4am which didn't happen as the SOC was below 100%. You can see the ones between 8am and 4pm worked as the SOC had reached 100% at the start.
