KeyError: 'air_temperature' in HA

Seeing this since quite some time now, I think it's similar to #126:

I really should just make everything optional in all honesty - but how useful is a weather sensor that doesn't publish air temp?

I agree. Either they have issues on the API servers or there's a problem on my station that is not sending data. I'm not home now, so I can't check. Will let you know.

In either case, the API clearly does not return data even when it's "required", so I would make everything optional. Eventually you could raise a warning in the log when a required field is not present in data.
