I am trying to install the lzw30 in a 4 way situation. It is a large room with 4 dumb switches that control the lights. I wanted to install the lzw30 in a single gang junction box. When I opened the box I found two red wires that I assume are the traveler wires attached to the dumb switch. There is only one place for a traveler wire on the smart switch. I do have a neutral wire.
@stan - It sounds like you found the 4 way switch with two red travelers. You won’t be able to install it here. You need to find where the source from the load center arrives. See attached photo.
