Hi @vedakbo2
Thanks for the inquiry, and welcome to the Roku Community!
Please be advised that a Roku streaming stick can turn on/off your TV and change the volume if you are using a Roku voice remote that can control your TV; this feature needs to be set up during the initial setup process, and not all Roku remotes have this functionality.
Feel free to contact us again if there's anything else we can do to assist you.
Cheers,
The Roku Community Team
