Need a little direction looked at the set up for this configuration 4way mechanical switch replaced by the MSOP-5SM (occupancy switch) and 2 companion switches but instead of showing the 4 way it shows a companion switch going in its place . I thought I saw the instructional for my situation but appears not and I am left with no lights but a clicking sound on the MSOP-5SM when I hit the companion switches. Would anyone jump in and advise me where the help for this would be. Much appreciated and thank you Laurence My config is; switch one 3 way( line power in ) - switch two 4 way and switch three , 3 way.
