Seand when using export/discharge schedules on WW, the start/end times are reset to 00:00 at the end of the schedule, also DC discharge is disabled, see here:
WW uses Slot1 in the Giv settings. Depending on your inverter/firmware, you may have 10 slots available but, that becomes irrelevant with DC charge disabled.
It's generally a bad idea to have multiple systems controlling the same thing, as they either argue, or just don't work, so I would stick to either Giv internal settings, or WW external control.
My preference is for WW, as it has more features and manages the IOG integrations.
