App does not handle when integration is unable to communicate with car.

For some reason car couldn't be woken when charging should begin.

The app reports charging but it never succeed with the command to the car.

Not sure if you can get any status back, or we just need to check it.

Yes, the app does currently not validate that it actually was able to start the charging. This can be improved.
