I am trying to control 1 device(lutron lighting for example) using 2 controllers. i would like to be able to do 2 way control and receive feedback. Anyone done this yet? I would like to use RTI and Savant to get feedback on this and potentially other devices. I was thinking of just using a y cable/or making my own but I dont know if i need an active device in between for a potential ground issue or to avoid any voltage problems or handshaking although i dont think for simple feedback there would even be a handshake. thanks for any feedback.
