Finaro Dimmer 2 install in 4way momentary circuit with 1 switch

I have been having trouble installing last dimmer in our flat in a circuit that has 3 momentary wall switches and one switch in a fuse box.
I have a spare Fibaro Dimmer module but not sure how to install it. The approach that i am trying is to to install the module prio to the fuse box switch. I am attaching the photos the switch:

Can someone point out how the dimmer module should be incorporated here?

Let me know if there is any additional info that i should provide,

Thanks in advance!

First point is: you need to obey your local laws when making changes to your home power circuitry.
Second point : ask an electrician if you don’t know how to do it.
Third point : look at the examples in your manual, there are a lot of.

Fourth point : I did the same to my circuitry and could not get it to work. I solved it with an additional low cost helper relay (something like this one https://www.amazon.de/dp/B000UWD6RW/ref=pe_3044161_189395811_TE_dp_1) which gets switched via the wall switches (voltage free) and then connects to the Fibaro Dimmer (voltage free) like described in the Fibaro manual. Works great.

Good luck.
