If you have an integrated vehicle, you can use the ev.energy app to track your charging on the go. You log in with your vehicle credentials on sign up - or, if you skipped this, just head to Settings > Vehicle details and update your vehicle.
Unfortunately, if you have an incompatible vehicle and a Rolec HomeSmart EV you can only use the ev.energy app to track your charging at home.
We're working behind the scenes all the time and we'll be rolling out support for other vehicles in the near future. Check our list of current compatibilities here: What cars and chargers do you support?
