• We set the charginging to 12:30 - 4:30 for Octopus cheap reate
• Car was low (about 12%)
• Plugged the car in at 11.m and checked scheduled charging was on (as above and 80%). All looked fine, and waiting to charge
• Next day I looked at car and to my surprise it was still charging at 11:am
• Looked at charge seetings > scheduled charging settings and it was now off and times were all at default --.-- and no 80% limit as had been set
• Checked the Bright smart meter app and it seems the car had not started at 12:30, but had actually started at 5:30

(I checked the car's clock and it was set correctly)

Does anyone lknow what could have caused this to happen?

Did you have a departure time set on the HVAC? Not sure, but I think this can confuse the scheduled charging.

Also, did you set the times in the off-peak section so that it would only charge between those times?

Yes we had a departure time and only to charge between those times.

it has been set like that for months and until now always worked exactly as expected

Ah, right. I've had that happen before randomly. No idea what causes it. Last time it happened, it charged past 80% to 83% and flattened the 12V battery!
