I think something has changed at Nissan at the beginning of October. Stuff that no longer works: HA

The Nissan android app (now says “The service cannot be provided Please try again or contact NISSAN”) The android myLeaf app

I did some digging into this, and it appears that the EU app uses kamereon api, which is the same as renault… So maybe the renault codebase can be leveraged to output nissan data…
