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…
