Hello, since last update of the Home app, sreen casting doesn't work anymore. I still can cast via YouTube and other apps, but not via the home app, where the Tv screen  turns black. I use Android 10. After removing the tv (Chromecast )from the app, it can't be added again....

I used home for years....

Can this be solved?

Hi Manuquick,

 

Thank you for reaching out to our community.

I understand that you have been unable to use screen mirroring from your Android 10 device to your Google TV since the last Google Home app update, even though casting from individual apps like YouTube still works. I appreciate the steps you’ve already taken to resolve this, such as removing the Chromecast from the app and attempting to re-add it. I’m happy to help you find a solution.

To get started, please provide a bit more information by answering the following questions:

  • Which model of Chromecast are you using? Here's a Google Help Center article that can help you identify your device: Chromecast and Google TV Streamer specifications.
  • What is the current color of the LED light on the Chromecast?
  • Are you receiving a specific error message in the Google Home app when you try to re-add the device?
  • When you removed the Chromecast, did you simply delete it from the app, or did you perform a full factory reset on the device itself?
  • Which version of the Google Home app are you currently using?
  • Is your smartphone’s operating system fully up to date?
  • Could you please check if "Power Saving Mode" is enabled on your smartphone?
  • Are your Chromecast and smartphone connected to a 2.4 GHz or 5 GHz Wi-Fi network?
  • Is the Chromecast plugged into a USB port on the TV or directly into a wall power outlet?
  • How far is the Chromecast from your router?
  • Have there been any recent changes to your router settings?

Please reply with these details so we can work toward a solution for you.

 

Best regards,

Virna
