Additional information

This maybe related to Bump pychromecast to 14.0.0 which was part of the 2024.3.0 release. Restoring HomeAssistant back to 2024.2.5 resolves the issue. The Google Cast screen displays, shows the 'Connected' prompt but stays on the splash screen never showing the lovelace view until it times out and exits. This was done on my Google Nest Hub.

I second this, same behaviour, started after 2024.3 update. Wanted to add that sometimes the dashboard still comes through somehow, maybe 1 out of 10 times or so. Got it to work after rebooting Google nest hub this morning but now it doesn't help.

Same problem here... rolling back to 2024.2.5 resolves the issue.

Same here, interestingly the UI is able to cast dashboards still reliably from the media player component. So casting isn't 100% broken.

This seems to be specific to the show_lovelace_view service. Wondering if some changes were missed in the service.

To me the behaviour is as if the URL is not constructed correctly when sent to be casted as the behaviour is the same as if you enter an invalid dashboard-path.
Also If you look on the media player for the cast device, it is not displaying a dashboard that is attempting to be casted. Where as in 2024.2.5 it is being displayed.

Also seeing the same problem.

Same problem for me too

[MarkKlerkx]

Same here

Same problem here, displaying anything else on the cast screen like images or media seems to keep working tough.

Thought it was an automation issue, as it worked trough sending a dashboard from the media player but not trough my automation's.

For those looking for a work around you can consider using Cast All the Things. I reverted my automations to use this (I was using this initially before switching to Google Cast) for now and it's working albeit only locally. I don't believe CATT works for if your HA is externally exposed though.

Once installed, you'll need a shell command like this where -d is your device name or ip address ->
cast_message: 'catt -d "Nest" cast_site http://192.168.1.131:8123/lovelace/2'

Use this in your automations ->

• service: shell_command.cast_message

@kwkid maybe it’s good to add the documentation link in the issue: https://www.home-assistant.io/integrations/cast
So the tags are automatically added by the bots and gives the issue maybe more attention by the code owner

done

I am sure my issue started even before 2024.3.
Mine will sometimes display the dashboard then continually try to refresh reconnect until finally failing.
