Re: I have a Roku Ultra Streaming Media Player 4K/HD/HDR 4670RW. How do I power off Roku itself?
Roku's do not turn off. There is a bandwidth saver that should cut the connection after a few hours of no interaction. Otherwise, get in the habit of hitting the HOME button before turning off the TV. That will cancel out any running channels and the bandwidth usage will be near zero (just occasional channel and firmware update checks.)
