Turning a TV off from your phone always works. Turning it back on needs one setting on the TV, because a sleeping TV only listens for a “wake up” signal if you allow it. Most TVs ship with this turned off. It takes a minute to switch on.
Roku sticks and boxes don't power off. They control your TV's power over HDMI, so Power works only if the TV supports HDMI-CEC.
Works with TCL, Hisense, Philips, Sony and other Google TV sets, plus Chromecast with Google TV. Support is new: if something doesn't work, please email us your model.
Works with Fire TV sticks, cubes and Fire TV smart TVs. Support is new: if something doesn't work, please email us your model.
Good to know
Keep your phone on the same Wi-Fi as the TV. Menu names vary a little between models and years.
Some TVs stop listening after a long deep sleep or with energy saving on. If power-on works in the evening but not the next morning, check the TV's energy settings.
