The charger is unusable if you want any control over it whatsoever. The SmartCharge app is terrible. You're supposed to be able to set up schedules to take advantage of cheaper electricity yet this does not work. You're supposed to be able to choose the charging speed, again this does not work. To top it all it reports it's not plugged in yet on the same screen says it's charging. As for the customer service, you just can't get an answer. Currently costing me £4 to charge my car instead of just 25p because we can't schedule it. I have to set an alarm to switch the unit on after midnight by the mains switch. Wish I'd never had this piece of junk installed.
