No data from and to vehicle - need to restart homeassistant to get it working again #375
Description
The problem
Since a few weeks I don't get data from the vehicle after some time (hours). The only way to recover is to restart homeassistant.
In home-assistant.log I can't see particular issues but only errors that are a consequence I believe. I put an example of a log entry of the time when a script should set a charging break - please see in the logs section.
Please note: all other entities are wrong (=old). The log only shows something that I can see that might be of help.
What version of MBAPI2020 do use?
v0.29.4
What was the last working version of MBAPI2020?
