Config Insteon ir link

I need information how config insteon ir link, roomie only detect Insteon Lighing

The Insteon IR Linc is an infrared product. It’s not on a network. So you control it with an iTach. Infrared is one way, so it isn’t “detected”, but rather you select the iTach, then select type Auxiliary then “Insteon” and that will create the IR Linc device.
