3-way switch with z-wave relay

Hi, I have the same problem but I am getting voltages floating as high as 140v as I am in the uk with 240v mains. I lack much electronics knowledge but quite happy with house electrics. Could you define the purpose of the green and white connections you note above. I am assuming they are the switch input to the device and the neutral input to the device but would like to clarify. Also, as I have 240V would the resistor need to be the same I.e 1momh do you think or something different. Finally did you attach the resistor internally for safety, neatness or some other reason. I was planning on leaving it outside the device but with proper insulation around the connectors to ensure good heat dissipation. Thoughts much appreciated.

i have the vision ZL7432US with dual relay. does anyone have a diagram of how to wire this up on a 3 way switch setup? I have mine hooked up to the load 1 wires (blue to the switch’s common and red to the light). I have green and yellow capped seperately. it turns on my lights but sometimes, it doesn’t or it stays on regardless of the manual switch position. Please help. thank you.

@mtnbrit would you be willing to do a tutorial on this? Or maybe point us to one that is pretty similar? Thanks!

@Awhitton did you happen to do this yet how has your experience been? I am looking for a short tutorial on how to set this up on mine. Would you be able to post something on how you did it or if there is something out there close to what needs to be done can you point us there? Thanks!

@mtnbrit
Is the below image what we would need to do for the modification? Thanks.

Sorry, I never progressed this as not confident of the way forward. I was thinking of just putting wireless switches in place and not bother wiring to physical switches. More xpensive but gets job done.

Did you need to use a 4-way switch to get it work correctly or are you using two 3-way switches?

Thanks.

In my house I did not change out any of the 3-way or 4-way switches (with 1 very odd exception) but also most of my 3-way switches had the line and load both in the same electrical switch box which is the easiest scenario.

I primarily used Vision relays throughout my house. The concept is virtually the same for a single pole switch vs a 3-way or 4-way switches as long as the line and load are both in the same switchbox.

The way I have my Vision ZL7432US/Monoprice dual relays wired is: (the one prerequisite is that both loads much be on the same circuit)

  1. White relay wire is connected to the all neutral wires (white) coming in from line (circuit panel) and going out to the load (lights).
  2. Black relay wire is connected to the live wire (black) coming from the circuit and goes to 1 screw on each switch
  3. Blue relay wire goes to the other screw on switch #1
  4. Red relay wire goes to the load wire (black) that goes to the light #1
  5. Green relay wire goes to the other screw on switch #2
  6. Yellow relay wire goes to the load wire (black) that goes to light #2

The 3-way scenario I’m speaking to is Option #9 found here: https://www.easy-do-it-yourself-home-improvements.com/3-way-switch-wiring-diagram.html

If you have 3-way or 4-way switches, the #2 mentioned above has the line wire (black) going to the 3-way/4-way switch first (which is how it is probably already wired) and you connect the Blue or Green relay wire (depending on which load/light you are controlling) to the returning 3-way switch (the last switch that connects to the load/light) from the other 3-way/4-way switch. The easy way to think of adding a relay (regardless of single pole/3-way/4-way) is to identify the wire that comes from the switch and goes to the load/light and that is your relay insertion point. Just be sure that when wiring a dual relay that you keep the appropriate relay wires paired (Blue and Red are for 1 switch and Green and Yellow for the other). Obviously you also must connect the white and black relay wires to the line wires coming from the circuit panel.

I hope that helps.
