I have been trying to make this work for a year. I follow the process exactly as described but charging keeps coming immediately. Tried again last night.
Car only needs 20% to full (about 3 hours). At 7pm arrived home set departure time next day 8.30am) and preferred charging period 1am to 8am. Pressed on after closed down screen. Plugged in car (blue flashing) but car was actually charging. Remote says it was awaiting charge, screen in car said it was awaiting charge (in Blue) but car was actually charging. Went to remote stopped charging and got message "problem with preferred timing" restarted charging and got awaiting charge. Car stopped charging and charger light flashed showing it was awaiting charge. 30 minutes later car started charging again. Was going to give up until I saw your post.
By PCST do you mean set 1am start by do not set a finish time. Is that possible?
After writing the original post many months ago, I’ve actually given up completely on using it, as even when it worked, it was too much of a faff. I now rely entirely on the mechanical timer in my charge point, over-riding it or changing the times when necessary. I’ve also become much more relaxed about not charging to 100% - if I can be bothered, I change the timer, or, more often, wait until my %SoC is down to c40% which means a 7h charge leaves me well under 100%. But I don’t fret about it.
All this is not much help I’m afraid, but as I am also away from my car for a couple of months, I can’t try anything.
My only off-the-cuff comment is, for how long does the car charge when it starts? I think, from memory, that it always charges for a minute or so before “sleeping”. Logically, it has to do this so that it “knows” how much power will be available when it does need to start, so it can work out if it has enough time in the set window.
The only other suggestion would be to try setting a much later DT (say 1800 next day) and then change it back to 08:30 with the app when you wake up.
Or fit a mechanical timer...
