Importantly: The wattage has to be right, if I connect two devices there lying together more than 30 watts standby it does not.
In addition, the binding works with my remote (Samsung) not using any key.
I do not know why, but the "off button" wanted the unit for longer than a few days akzeptiern.
Now I have another key made, and it works flawlessly.
Very rarely I have the problem that can not be shut down because the TV is very short on the threshold 30W with its standby.
Then I pull the unit briefly from the can and put it right back on, then it works again.
But quite clearly lacks an adjustable switching threshold, which would broaden the scope considerably.
Recommendation: If you have standby numbers which should be about 30W rather resort to a socket with footswitch.
