I have the same problem. I’ve noticed that my nest hub has been updated to fuchsia os, so I’m not sure is only a timeout problem.
Hope that someone finds a solution.
To avoid fuchsia upgrade I suggest to disable “preview program” for the nest hub on the google home app. This will prevent upgrading, at least until fuchsia turns to stable release.
EDIT. For anyone having issues with white screen, try casting your view to your TV or somewhere else that’s NOT the Nest, and then try connecting to the Nest once more. For some reason this fixed my problem, at least for the time being.
Hey Guys! That lovelace views can be sent to chromecast is brilliant. the only problem i have is that the background of the displayed lovelace views on chromecast are always in white, although it is set to black and is displayed correctly in the browser. i want them to be black, because i’d like to use the chromecast as a smart mirror.
any advices, how to get the background in black? any special parameter to be set? here is an image, how it’s been actually displayed on chromecast
Upgrading to the latest Home Assistant build I don’t have any issues with timeouts but it seems like the hub doesn’t accept any custom backgrounds, from auto dark / light or manually setting a theme with a specific background, when I cast all the cards are themed correctly but the background is always white. I assume the hub’s browser needs a specific flag or something to set background from white, anyone had luck with this? it’s a little too bright at night
Had same issue with history not displaying and custom cards not showing graphs. Just updated to 2021.12.1 and issues have been.resolved. Release notes do mention cast issues that were resolved but not specific on what was fixed.
Resolved for me too. An automation to show Cast on a Shield TV also now works, but I do need to wake the device first, then add a 5 second delay before casting a view.
