Hi @Artemus4,
Greetings from the Roku Community!
We understand you are having a problem with the Google Home because it was unable to recognize the Roku TCL TV. We're happy to assist you further.
Before using Roku Action on Google, ensure your Roku device is running Roku OS 9.1 or higher. You can find the software version by visiting Settings > System > About. Your Roku device checks for an update every 24-36 hours, or you can manually check for a software update if needed.
We hope this helps. Please keep us posted on what you find out.
Best,
The Roku Community Team
