A strange one last night. I had a full battery so set an export schedule in WW which for some reason didn't run so I used the " Quick Settings " button in the Giv app to force a discharge then set it back to Eco before bed. Woke up to a 5% battery. Looking at the Inverter settings I see that as each overnight charge slot completed, the battery started a discharge. I checked and there was nothing set in WW Schedule ( which was inactive ) but I deleted the shedule anyway. When I fired up the " Inverter " app on my iPad I used the inverter controls within the Inverter app to set the battery to charge, which it did. I then set the Inverter app to " Normal " and instead of going back into Eco mode it started an export to grid. Couldn't see anything in the Giv logs so I did a reset inverter in the app which seems to have righted the problem. 
EDIT: Can WW take a look at my settings and check it wasn't something I enabled accidentally please.
