Save JSON-Parse-Errors in _debug-Channel

[margau]

It would be helpful if a user can see JSON-Parse-Errors, so i would suggest to save them in the _debug channel - combined with a certain error code.

I'd rather make a subset of the logs available to the user in the web interface. Makes for an easier debugging than having to somehow get the info from influx, and offers better protection, e.g. for public sensors

That would be an good alternative too - but where to store the Data?
