How to configure Fibaro FGK10x Door sensor

Hi,
could you please help me to configure the FGK10x Door sensor?
My goal is to obtaining a notification when the window is opened or the shutters is moved.
So I’m going to connect an external sensor to the FGK10x. How can I connect it?

I’m using a Raspberry where I have installed Home-Assistant and I have plugged a Z-Stick Gen5 as controller.
Further I have a node connected to the controller, the Fibaro FGK10x Door sensor.

If I’m moving the magnet, the sensor icon turn on an icon and “Fibaro … Access Control” icon changes the value to 22.
While if I connect the shutters sensor to IN and GND inputs, the magnet sensor stops to working and if I move the wire sometimes the sensor icon turn on.
In this link you can find out the node configuration file.

I have also tried to create a post in the fibaro community.

Please help me.

Thanks
Francesco

What I see in the states section:

In another forum, in this post, an user (petergebruers) told me that it’s not possible use the magnet sensor and an external sensor at the same time because they are in parallel. Removing the magnet, it’s possibile to use ONLY the external sensor. So it’s not what I need…

Can someone recommend me an another window/door sensor where I can connect the shutters sensor to it?
