OK - here's a basic question from the great uneducated. I am running HomeSeer software with a CM11A interface set to house code B. I also have a Leviton Amplifier/Coupler and a plug in noise filter for each computer in the house. I can send and receive fine on house code B but none others. Do I need a seperate CM11 for each house code I want to use? Or should I be able to see all the X-10 devices?
