I got the IO on cheap rate for half the session again, although they stopped my EV charge prematurely because I was ramping up the charge rate in excess of what they were expecting. But as long as you don't unplug the car.........
Luckily SWMBO came back from work not long after so plugged her EV into the second charger on full power which filled up to 100% in the final minutes of the adjustment window.
I'm expecting a 50k+ Octopointer for this last session.
Is that how it works? EV is plugged in, power across the board. Disconnect EV and its back to normal regardless of still potentially being in the window?
On a Tesla (don't know if it works on other brands), if you set a low charge rate in the EV app like 5A or 10A and a 4am departure time at 100% SOC, the IO thinks its going to take a LONG time to charge so it gives you extra slots early in the day before the cheap rate slot starts. Hence every time I am getting cheap rate at midday or 2pm even with the car at 60%. Once you have a charge plan agreed in the IO app, If the charging stops because your scamming it by increasing the charge rate or you set a lower SOC cutoff in the EV app, or it decides to stop for whatever reason, as long as you don't cancel the plan or unplug the car you still get the charge plan at cheap rate for the whole house. Some folk on the facebook forum even say you can close the app but leave the car plugged in (I have not tried that).
The only drawback is I cannot unplug the car and use it until tomorrow. Also I change the SOC cutoff to a lower rate in the EV app so it does not charge more than 6 hours total as that may mean they could charge me peak rate on the hours outside of the normal cheap slot if the actual charging exceeds 6hrs. So if its an actual charge of less than 6 hours on a plan of 10hrs I still get the full 10 hrs at cheap rate for the whole house which could include the second EV on a separate charger.

Example of IO manipulation from a saving session last month with nearly all of the in day adjustment window at cheap rate even though it was in the afternoon.
Only problem is you don't know if it worked until you get your bill.

You need to document what you did and then wait a few weeks to see if it worked. The great thing about a saving session day is you don't need to document it because you know exactly what you did.

This is pretty much what I do and I switch the app off before I go to sleep and back on again at 5.30am.
I actually use less electric as I am not trying to heat the house during the coldest part of the night, plus I don’t get close to blowing my fuse now due to overloading the house

IO normally rounds up the 1/2 hour slot
So if you get a schedule at 7:59 the off peak starts at 7:30, and the same if you unplug at 7:01 and you had a schedule until 7:30, the off peak will finish at 7:30

I sometimes go out several times, after I have got schedule, and it sets another schedule and all have been off peak.
