Charge history, HVAC history, reset HVAC schedule, full error messages for EVs/PHEVs

[jumpjack]

Now working to a standalone Android App:
https://gallery.appinventor.mit.edu/?ga ... ead07c2545

No external servers used, no credential stored, as visible in the source.
No APK provided, so everybody can check the source before uploading app to the phone; you need to register to AppInventor site, then you have 2 alternatives:

install MIT App Inventor Companion App on the phone, and connect the phone to the PC to temporarily upload the app to the phone
or
build your own APK from APP Inventor site and permanently install it on your phone.


Advantages w.r.t official app (once this app is finished):
- viewing complete error messages rather than "ops, something went wrong"
- reset HVAC schedule and set a new schedule without need to be in the vehicle
- set HVAC temperature (but a bug on my vehicle automatically always reset it to 21°C...)
- setup HVAC start at a single specific date/time (not affecting schedule)
- download charges history

All above features have been already successfully tested in javascript version of the app.

Some additional features appears to be available in the Renault server but protected by a further security layer based on "SRP authentication" (currently under investigation):
- door lock/unlock
- windows open/close
- horn activation
- lights activation
- trips history

But it is also possible that these are only available for Nissan vehicles.
