Do you have control/information about door windows ?
If they went down during winter (long press on FOB, or any were not closed for some reason) - the car could in worst case get filled by snow.
Could the app notify/warn about being parked with window(s) not up ?
The "vehicle information" displays a lot of "options" - BS00, BX60 and so on - it would be far more useful if those had a short description.
Indemo mode:
in the "home" view, everytime HVAR or charging is toggled, or any command is sent - a huge popup spawns like something in windows from the 90's , then the battery is "animated" from 0..to 70%" , that's just a "noisy" user interface (I will not even mention the vertical scrolling)
I would use this app in the morning/evening , or especially during winter (which is always dark at this latitude) - so the bright UI is really not easy on the eyes, an stylish, black UI like the original app would be nice - are you going for some redesign/improvements anytime soon ?
As is- I consider using the Tesla app, then having your app do the dirty work in the background (scheduling, warnings etc) - would rather see one both do the job, and look good.
