I had a simialr problem when I had the Ohme app on 2 phones! It got very confused.
The app works and the Enyaq system worked - but not together.
The charger does seem to need a good internet connection.
My Enyaq 12v system failed after 2000 miles and its been in the dealership for the past 12 weeks - so I am forgetting!
But my rental (thank you Skoda warranty) is a Ford Mustang Mach-E - which doesn't really let you change the charge settings. It works fine with the Ohme charger.....so the charger isn't the problem!
(The Ford, by the way, is excellent and range is well over 300miles - I think Ford spent more money on it than VAG did!...and it has an interior ambient noise feature that can be selected - a V8 rumble that satisfies my petrolhead tendencies. I have done 3000 miles in this so far.)
Despite its over-complicated charging, I do miss the Enyaq though, its lighter to drive and mine has a sunroof.
Is the new app working any better?
My Ohme charger has switched to German, so I haven't a clue what I am doing on it now!
