The Power Button should be able to turn on/off other devices (especially TV & AVR) beside just the TV. CEC-HDMI would be the best way, but even if the other devices were controlled via IR, the remote would be more useful.
I have a simple Home Theater (Samsung UHD TV_Denon Multi-input AVR surround system) I would like the remote to be able to control the TV and AVR on/off with the Roku POWER Button. I have to use multiple remotes to turn this simple system off/on.
