Prestigo is based on Infrared signals as the majority (99%) of the audio/video devices on the market use IR signals.
Some exceptions are Bose (RF) and Sony PS3 (Bluetooth). These devices can be added and controlled if they have an IR receiver or IR dongle attached to it.
The WII (RF) cannot be added to the Prestigo device list.
