AttributeError: module 'homeassistant.util.yaml.loader' has no attribute 'SafeLineLoader'

Seems like an issue w/ the upstream library. I'll look into it later, just documenting atm.

The yaml loaders were renamed in this commit

https://github.com/home-assistant/core/commit/e49f6b41eeb1009fe00376e1358c85739312a302

Looks like a quick bandaide would be to change all references to SafeLoader to FastSafeLoader. I'll give it a try when I get home today.

Oh and 'SafeLineLoader->PythonSafeLoader`

[Petro31]

There's a new error w/ beta2 which breaks this again. I won't have time to look at it until next week, which will be after the release.

[tbrasser]

This seems to work for me :) #58

The fix by @tbrasser has been released!
