Turn the TV on from Kliky

Kliky can turn a TV on only if the TV stays connected to the network while it sleeps. That is a setting on the TV, and it has to be enabled once. Not every model has it.

If it still does not turn on

Press the button on the TV once. From then on Kliky controls everything else. A TV that was unplugged also needs the button the first time.

Turning off

Power off from Kliky works on any connected TV, because the TV is online at that moment.
