Wire this to the AC device you wish to control (110vAC or 220vAC), and the sensor detects light from any infrared led (does not distinguish between different button-presses or manufacturer codes on your remote control), and switches your device on.

It can be set to operate in either latch or momentary mode, so you can have your device switch on and stay on until you press a button again, or you can have it only come on while you are holding a button on your remote control.

Now you can switch on the lights without getting up, just make sure your new remote switch isn't getting any unwanted IR input from, say, trying to change the channels on the TV in the same room.
