Chromecast specfication

My parents have a few chromecasts, one in their room, one in the basement and one in the living room.
On HomeAssistant how do I choose which one to use. I know about entity_ids but i don’t know how to originally select which cast I am referring to under my config
This is my config:

media_player:

  • platform: cast
    name: Cast

Under ‘Developer Tools’, click the States button. This will list all the entities in Home Assistant.

The entity_id will look something like ‘media_player.chromecastname’

Got it thanks. The problem was some chrome cast python file didn’t download so media player wasn’t even there. Once I downloaded it and went to where you said I found it.
