but you get off peak 23:30 to 5:30 anywayNow that's an interesting thought.
If you do that, OI will factor a lot more time slots than perhaps needed. But you will defo get your car to the charge you set.
I'm not clear if OI will cheap rate all those slots, even if they're not being used by the car. It wouldn't surprise me if they do. They may also see that as gaming the system at some point in the future.
As long as you set up to finish your charge for, let's say 6:30 - in 90% of cases your charge schedule will be done during these off peak hours. Only on some occasions with Octopus will see that it is not enough time (or when power is cheapest) - it will allocate time in those specific slots.
but in my cases, as soon as I put anything but 100% charge in Octopus app, my charge finishes quite below the charge limit set on car. for example, if I set up 80% charge limit on the car and 80% on the app, I end up at like 70% or so. Not sure why it is like that but this is my observation
