I just bought a 58" TCL TV with roku built in and could not get it to work with homeassistant. It would go offline after 20 minutes of being powered off. I have my IOT devices in a clan with no internet access but I decided to update the TV and it still didn’t work.
What I found out I had to do was update the TV AND create a roku account so that this would finish the update. I then finally had the fast startup option and enabling that it works now! Even with internet access blocked again.
Hopefully this helps someone else.
Thanks for the info. After all the ads and tracking nonsense I just took mine off the network all together. I’m lucky enough to have the harmony and Android tv states to fall back on for automations. But this is good information in case my setup ever changes.
