Your live goes into the L terminal on the dimmer and Sx is the constant live that comes out of the diner to your switch. Then your switched live comes back out of the switches to S1 on the dimmer

Yes, i have the same problem in my old installation. This is so called "intermediate" wiring. On first switch (2-way) come live wire (Phase-P or L) and two wires (1 & 3) which go to another switch (indermediate) and then go to the last switch which is another (2-way switch) to contact 1 and 3. P on last switch go to the light... Check picture (in picture i have two intermediate switches)....

 

In this wiring is problem, because you need you fibaro module in the side of last switch (last 2-way switch), because of light wiring. You can resolve this with replacing all switches witch momentary/push switches....Just connet 1's with live wire and 3's with other wire in all momentary switches. check shema in manuals for momentary switch.... That's all.
