You want car charged to 80% by morning. Your car is already charged to 35%. Set ohme app to charge 45% by 5.30am (I found that you will actually need to set it too 48% ish because it uses some extra energy for the charge process, generally more the colder it is).
That also describes what the guy with the MG4 was saying, in that you have got to the charger, the % of charge required to top up, based on the level of charge in the battery. Which is a bit weird (primative), you have to do the sums, rather than the charger calculating them based on the level of charge set in the app.
You will find I’m not the greatest fan of Ohme chargers, compared to others on the market, I’d choose to install but, hey ho beggars can’t be choosers 🙂
