Google Cast devices like Android TVs and Chromecasts will be automatically discovered if you enable the discovery component. If you don’t have the discovery component enabled, you can enable the Cast component by going to the Integrations page inside the config panel.
The Cast component has some extra configuration options available for advanced users. You will still need to create a config entry to initialize the Cast component.
For example, Cast devices can only be discovered if they are on the same subnet as Home Assistant. If this is not the case, you want to configure the IP address of the Cast device directly:
# Example configuration.yaml entry cast: media_player: - host: 192.168.1.10
(list)(Required)A list that contains all Cast devices.
(string)(Optional)Use only if you don’t want to scan for devices.
(list)(Optional)A list of Chromecasts that should ignore CEC data for determining the active input. See the upstream documentation for more information.
If you want to manually configure multiple Cast media players, you can define those as follows:
# Example configuration.yaml entry for multiple devices cast: media_player: - host: IP_ADDRESS_DEVICE_1 - host: IP_ADDRESS_DEVICE_2
