New Cast devices not appearing on HASS

After renaming my cast devices (I renamed them through the Google Home App and now they are called: Kitchen, Hallway, Living Room,…) they are not appearing on my HASS.

This is the content of my configuration.yaml file:

media_player:

  • platform: cast

cast:
media_player:
- host: 10.0.2.44
- host: 10.0.2.45
- host: 10.0.2.49
- host: 10.0.2.51

I believe this is the right way to do that, but I cant see the media player on HASS.
Also, let me point that I’m not using the “Cast” feature from the HASS → Config web app config utility.

Any possible troubleshooting?

Why not?

I’m pretty sure I had to set this up to get mine working.
