Two-way switch with intermediate switch

Hi.

In my case i have situation in my hallway like shown in picture 1. This is also known as two-four-wire system wiring or a “hotel” wiring system. There is no N(neutral) wire in swich-boxes. So, in this case Phase(Live wire - L1) came to 1st two-way switch and then go to 2nd and 3rd switch (intermediate switch) and then go to the last two-way switch and then to junction box L(phase) on Light. (Check picture 1).

Now, I want install fibaro relay switch in the junction box in the other end of my hallway, because there i have N(neutral) wire to power supply fibaro relay, but there I don’t have same Phase(live-wire L1), just live-wire L2. Is there any way to work fibaro relay if I connected wires like on picture2 ???

Sorry, for my bad English…

Did you try it, does it work? If not, you may try a Fibaro dimmer, who has a function for 3-way switches (parameter 17=1).

Not yet. I’m on business travel. When I come back home i try…
