We are going to begin building our house soon and I am weighing my options for lighting control. I will be installing Leviton Security and automation, and I am trying to decide on lighting control. I am trying to decide between UPB switches from Leviton and the Omnibus DIN rail system. I would choose Omnibus for better reliability and flexibility, but I have not seen much use of this system in the United States. Is the system primarily designed for Euro installs? Does anyone have any insight to the pros and cons of the Omnibus system?
