3 toggle switches (3-way, 4-way, 3-way) US with neutral

Question

Posted (edited)

I've been searching the forum and google but only getting myself more confused since much of the information I found refers to UK and 2 wire installations.   

 

I have a newly wired house with several rooms configured with LED wafer ceiling lights controlled by toggle switches from 3 different locations.  I'd like to install a dimmer 2 to control dimming using the original toggle switches (antique retro style button i.e. -

).  

 

The wiring configuration is similar to this:

Can someone help me understand how I would wire the Fibaro Dimmer 2 into this configuration?

 

I expect to be able to dim only using the app but be able to turn on/off the lights from any physical location.

 

Thank you

  • After doing some more research, I'll attempt to answer my own question.  Given the above wiring diagram would I:

     

    1. Place the Dimmer 2 in the box with the switch leading to the light.
    2. Disconnect switch output to light and connect to switch output on Dimmer 2
    3. Connect switch output to S1
    4. Connect neutral to N
    5. Connect (always) live from somewhere else in box to L on Dimmer 2

    I would appreciate if someone could confirm this is correct, or let me know where I went wrong.

    Hello. I should have some comments:

     a) Obviously, you don't know what to do. Electric devices should be done by an expert with electrotwchnical education. It is a property or do not give a life!

    b) Any scheme in the form of images of the switch does not indicate their internal construction, so we can only guess that the extreme are "alternate" and the middle is "cross". The whole is therefore connected in the so -called Staircase mode or control from several places.

    Always use only schematic signs.

     

    And now to your question.

    The basic misconduct is that you did not use the SX terminal to connect the control button/switch.

     

    Please see the scheme in the manual on page 9.

    By the way, on page 10 is exactly what you need.

    Control from more places, schematically drawn.

     

    1- Place The Dimmer 2 in the Box with the Switch Leading to the Light.

    Yes

    2- Disconnect Switch Output to Light and Connect to Switch Output on Dimmer 2

    Yes

    3- Connect Switch Output to S1

    Yes, but incominng to the switch must be sent from Sx!

    4- Connect neutral to n

    Yes

    5- Connect (Always) Live From Somewhere Else In Box To L On Dimmer 2

    Yes
