help needed: Walli Dimmer in "Stair switch" config

Question

Hi all,

I know this is a common question, however I did not find the answer to my question, yet.

 

I have two switches (no N wire) that switch the same light.

Setup is like this: 

One switch has Live and 2 Com wires connected

the other switch has the Load and 2 com wires connected.

 

Could someone lead me in the right direction how to connect Walli dimmers/switches (if that is needed)

Should I post pictures of my config?

 

cheers

All you have to do is think of the two physical switches as one logical on-off switch, and wire up per the wiring diagram in the fibaro manual. Use the wire from the right switch terminal marked P as the switch input to your fibaro device.

 

Select toggle as the switch type in the advanced settings, and do other configuration as normal.

    ok, so actually I do not need the com wires anymore, right? I think that's where I was struggling...

    thank you very much!

    Hello. Is the below diagram going to work, or I will burn something? I intend to use Dimmer 2 module.

    A the moment, I have 3 switches, connected in traditional way in a row - first S1 is connected to Lead, last one (S3) to the Light.

    There is no "N" available.

    I was following this diagram, found on the forum and instalator guide, but this applies to the Dimmer 1.

    Or maybe this would be better?

    Correct @Enriquez you don't need a neutral for the dimmer 2. (You might need a Fibaro Bypass is you have a load under 50W though).

     

    You'll wire up using one of the diagrams in the dimmer 2 manual, not dimmer 1. Choose the one that corresponds to your switch type - toggle or momentary.

    Hi Tim,

     

    In the manual, the momentary switches are between Sx and S1. Question is, can I provide "L" signal to S1 from L, instead of Sx ?

    No, you should only wire up as shown in the manual diagrams. Risk of fire or electrocution otherwise!

    With a bit of thinking, you can probably make this work.  For example, maybe you can change the location of the device - behind switch plate or behind lamp fitting, depending on what connections you have available.  Also, you can re-purpose cables - put some heatshrink on a cable to change it's designation.   I retrofitted Dimmer2's without needing extra wiring by putting in the ceiling behind the lamp.

    OK. I will answer my question myself.

    This diagram works, without any issues (I added the bypass to the light source):

    No any wire change needed.

    Since my question was about the Dimmer 2, not Walli, please move this to the appriopriate topic.
