Cannot log in to HA after repairing car to app

[newbuilder22]

What happened?
Tried to add an add on to Nissan connect EV app for my 2020 EV
Didn’t work so was told to delete car from app, set NC in car to default,
Reload car and pair to app
This did not solve the add ons not appearing in app but also made no log in from HA to Nissan

If you are using the NissanConnect EV app, this integration won't be supported, but the built in home assistant integration called "Nissan Leaf" should work for you. This app is only for vehicles that use the NissanConnect app.

Apologies I am indeed using the Nissan Connect app and this integration was working before trying to purchase add on and follow above. Vehicle is a 2020 UK leaf

Nissan had to intervene to recover the account.

The battery and battery status is not yet enabled - lNissan still working on it but the auto heat function is available. Is the battery issue stopping the log in?

Still cannot get this integration to log in

I can confirm that the user must have the battery management add on added to make this integration work. If you have other addons but not the battery then it will not load

[dan-r]

Just to confirm, the integration did not function correctly without the battery management addon?
