My chromecast audio devices all fail with the same message:
17-03-14 02:43:16 ERROR (MainThread) [homeassistant.components.media_player] Error while setting up platform cast
Traceback (most recent call last):
File "/srv/hass/hass_venv/lib/python3.4/encodings/idna.py", line 167, in encode
raise UnicodeError("label too long")
UnicodeError: label too long
I have discovery off and are referencing my cast devices as follows:
media_player:
- platform: cast
name: Hallway
host: !secret cast_hallway_host
