Erroneous charging at peak rate!

J1m

I plugged my EV in this morning, hoping for an early IOG slot, but the only ones given out were for this evening. I unplugged the car again as I needed it this afternoon and have not plugged it in since. The Octopus slots disappeared of course. I've noticed this evening that there have been two unexpected charging sessions, one at 8:30 to 9p.m and one from 22:30 to 06:00, obviously at peak rate up to 23:30 as the Octopus app is showing no charging slots and 'unplugged'. Screenshots of my WW activity log below (my SOC has generally been too low for my export schedules to run). I shall plug in my EV now so at least the 05:30 to 06:00 slot will be cheap rate!! Can you please advise Admin? Neat-permission

Similar issue has occurred this evening. I plugged the car in earlier, and Octopus allocated several continuous slots from 22:00 to 05:30. I unplugged the car as I'd decided to let my discharge schedules run, then plug the car back in to charge during the 23:30 - 05:30 period. The Octopus slots disappeared from the Octopus App. However at 22:00 my home battery started charging from grid (see screenshot). I tried setting a WW quick schedule discharge hoping to override it but it had no effect. I rebooted the Inverter via the GE portal which eventually stopped it for a while but then it started charging from grid again! I've now plugged the car in again and its started charging (Octopus slots have appeared again).

Update today (Mon) car charged okay overnight. I'm wondering if this issue is simply caused by plugging the EV in, receiving Octopus slots for maybe much later in the day but unplugging again before any charging occurs (which is probably not a 'normal' action). Even though Octopus have removed the charging slots, WW still has them registered and proceeds with charging at the allotted time(s)?

J1m We can confirm that Octopus left these plannedDispatches (schedules) in when we queried the API at 21:56 and kept them in until after 22:00.

See detailed logs below.

So, there's not much we can do about this. I would be surprised if they get charged full rate. If so, there's a bug at Octopus end where they still show us plannedDispatches despite the car being unplugged.

admin Thanks for the info. As you say it's obviously Octopus at fault over this, even though the charging slots disappear when the car is unplugged. I shall have to be more careful as to when I plug in!
