Detecting when no command are attempted or successful anymore.

[dglaude]

It seems that from time to time, the BLE communication with the car fail or TeslaBleHttpProxy is not even trying anymore.

evcc keep trying to change the car setting to follow the curve, but nothing is happening.

I wonder what could be done to detect those case, and then what could be done to unblock the situation one way or another.

Here are my logs:
