It looks like Google TVs should be added automatically, but I’m having issues discovering mine. I’m running HA using the docker image. My Docker host is on a 10.1.x.x network, while my Google TV is on a 10.2.x.x network. Their subnet masks are 255.255.0.0, so they should be on the same one from what I understand.
I tried expliclty configuraing the Google TV using
media_player:
- platform: cast
- host: 10.2.1.17
and I get this error during start up:
Invalid config for [media_player]: required key not provided @ data['platform']. Got None.
