Hi, I am working on a home that has the above system for what once was a home theater. VIZIA-RF is a discontinued system. It consists of two RZCS4-1L z-wave scene controllers (supplied only by hot/neutral/ground) located at the entry to the room. Leviton advises these require a remote for programming which is long gone apparently. And, in a back room nine (5 or 6 seem to do something) RZ106 dimmers (600w). Current system appears to have lost its program and only has some limited functionality. Wiring is with neutral but no travelers. Again, the convenient control in a 3-gang box at the room entrance. It has the current scene controllers.
I am looking for a cost effective “smart” system to replace this. Pulling wires for travelers is not a desire due to poor access but can’t be ruled out if the only good option. While not very elegant, one solution under consideration is to blank off the convenient controls, add up to 9 (non 3-way) smart dimmers and put an Alexa speaker in the area. The homeowner wants to be able to get the lights on “easily” from the entry to the room.
