Wiring issue with Fibaro Walli Switch FGWDSEU-221 switches in a two-way configuration

Questions & Help

Hello everyone,

I need help with a wiring problem I’m having with my Fibaro Walli Switch FGWDSEU-221 switches. I’ve installed them in my kitchen and living room to control my terrace lighting in a two-way (“va et vient”) configuration.

Here’s how I’ve currently wired the switches:

In the kitchen:

  • I’ve connected the phase and shuttle 1 to the L input.
  • I’ve connected the neutral to the N input.

In the living room:

  • I’ve connected the lamp return to the Q1 input.
  • I’ve bridged Q1 and Q2.
  • I’ve connected the neutral to the N input.
  • I’ve connected shuttle 1 to the L input.

My issue is that the light turns on when I use the living room switch, but not when I use the kitchen switch. I suspect the problem might be related to how I’ve connected shuttle 1, but I’m unsure of how to resolve it.

Would anyone have suggestions on what I could do to fix this issue? Any help would be greatly appreciated.

Thank you in advance for your assistance.
