I wouldn't set the minimum charge to 90% as it will always charge to that as soon as you plug it in and he won't get the benefit of the cheaper night rate. Minimum charge setting on the car ignores the off peak rate setting.

Set the minimum charge low, say 10%. The maximum charge to 90% and the off peak time to match the cheaper night rate, give or take half an hour.

I honestly wouldn't bother with using any smart settings on the charger itself as I've found them to be hit and miss. Set the charging unit to instant charge, or boost etc and the car will then request charging instead via the settings in the infotainment.

Ensure the checkbox is ticked too. I'll take a picture of my setup in a bit if you want?

Hi just wondering where you set the minimum charge, on the charge location I can see the maximum but no minimum. Same reason as the OP so trying to get the car to take advantage of cheaper energy tariffs. Many thanks for any help.

Many thanks both, also useful to know about using battery for pre start cabin temperature
