I have pm'd you if you want to try to work this through off the thread (its going to get annoying for the other users) but for starters step 1 - uninstall ev.energy app and reinstall it from App/Play Store (If you can sign up for the Beta release) Put in your ev.energy username and password and it should have your car settings stored in Account > Car Details. already without you needing to put them in.
Hi Craig
Just messaged you back, so sorry I didn’t see it originally
Short story is that after raising a few tickets with EV.energy they have pushed out an API update that seems to have broken with the last Tesla update. This seems to have done the trick and I managed to get it to smart charge last night
thanks loads for the offer of help though, appreciated
