So I've unpaired the Cupra from the Ohme App - I read on another forum that this pairing was causing issues for somebody.I have had exactly the same on my first charge after a few stop and starts the charging light on the car turned red and I had to unplug and plug in again to get the charge going.
Last two charges have been fine less not being ready on time due to smart charging extending the time. I think I need to play with the charging window to find the optimal time. Today I switched to Max charge to finish off the last 2%.
I've turned off having to approve charges (for the moment).
I've set a schedule in the car to charge to 80% and selected a 0000-0700 window (my cheap rate).
The Cupra App now shows "Charging Paused" - so hopefully it will start at midnight and in the morning will be sat at 80%.
