Satel i3 lite module

Hi,

Concerning the new Satel Integra module on the store I was wondering what the "ID" means when adding a widget, for example a button.

I can not find an option in Integra where I can assign and ID or anything else to a function and it isn't explained anywhere.

In short can I get an explanation on how this works and what I need to do to make it work.

The module says it is online for me.

We have an Integra 64.

We also have a KNX module in the Integra but from what I see it doesn't matter for this.

Thank you
