I have an Ohme charger with lekky from Brit Gas. Car is VW ID.3. I do a very low mileage and do not use the reduced-price “special” charging rate. I have set the max charge to 80%. I have not connected the app things. So, when charging is needed, I simply plug in the charger; it fills it up to 80%. When light goes from green to white, I unplug. No problems at all.
