EVCC Disfunction whithout grid meter

[stadlaa]

Describe the bug

Hello,
I open this Issue in reference to #13576 where my API had missing endpoints and the whole evcc seamed to stop working in the middle of the cycle when detecting the error that there is no grid meter currently connected.

I wanted to ensure that this is not a bug and expected behaviour.

Wouldn't it be a good thing if I could use evcc temporarily without a grid meter just for manual charge. Right know it seams to be useless whithout grid meter.

Steps to reproduce

What type of operating system are you running?

Linux

Version

Without grid meter we can‘t do PV charging, hence evcc waits for grid meter to come back online.
