Nest, problems with postal and weather info

Development

Hi i have an error with the nest and the postal code/weather info, see log. Maybe it has something to do with the space between numbers and char. In the nest i give up ‘1963 AH’

Not very helpful, but I can confirm you’re not the only one. I’ve got exactly the same problem with an identical stack trace (root cause a KeyError: 'my postcode').

Looking at the python-nest source, it looks like the postcode is expected as a key in the weather data that comes back from a GET to weather_url, and for some reason it isn’t there. I haven’t looked at the request and response data to check what’s going on. It could be a bug in the library rather than home-assistant itself.

If you avoid weather related conditions, the nest sensor works.
