So I have a Renault Zoe, 2017 model (41kwh - can never remember the exact model number!) and a chargemaster charger as provided with the car. I've just switched to octopus go because it seems like a good idea. Thing is I can't make the scheduled charge work, however I try it... I have a "my ze" account set up for the car (and am paying for it!) But no matter how I try to set up a schedule as soon as I try to save it the app tells me "UNKNOWN ERROR". If I set up a scheduled charge in the car (for 00:30) then plug the car in, the charge doesn't happen. If I set up a calendar schedule (in car) the car just ignores it and charges when I plug it in. I can't believe I'm just going to have to get up at 12:30 every morning to plug the car in - did anybody have any suggestions as to how to make this infuriating system work?
