Sometimes the EVCC cannot get the car to start charging. It tries 4 times. I would like to be informed on this. You see it in the log or int the app, but not a push message. If this message was send I can act in the car app to start charging.

Nice idea. However if we could filter the errors (e.g. regular expressions) using either white- or blacklists. For example I frequently get timeouts from reading the RS485 bus, which I can ignore. But I don't want to get push messages for this every single time.
