Controlling momentary external switch



Hi all,


I am new of the forum and a complete newbie in regards of house automation, I have solid background in information technology and electronic.


I am investigating to upgrade my current flat with some smartness. I believe i figured out most of the things that i need to do but as usual there is one part that i am not been able to figure out.


I have 2 switches on the wall. These two switches are simple push switch (press and they return, mono-stable). They are normally open switches.

These two switches have a live wire(220v) passing through them when pressed. The 220v goes into a relay switch that sense these current and switch state turning one the lights.


The relay in the fuse box is this:

(Unfortunately the relay is quite old and the only source i found is in Spanish... but the specs are understandable, i am living in Swiss)


Moreover the specs say that the max length for the impulse has to be max 500ms.


I haven't figured out a way to configure any of the Fibaro products in order to achieve this behavior.


Can you help me?

So Im guessing that “15489 relay” is a impulse relay. It changes state on a pulse from one of the push buttons

So if the switch board isn’t metal you can swap out that relay with a current fibaro switch or relay module.
