Get Instance created by a parameter as a nested family

Revit
1

Hello,

So, We have this panel which the components are placed as parameters, each position has its own.
Well, I was trying to get the elements inside the parameters. I was able to do this using Rhythm node, but its a mess.
I need to get the elements with the relative parameter, or at least some association. When I use getparametervalue it returns the familytype, no suitable for element.location node.

You should be able to select the element directly if you use the tab key or you can select the nested elements by category and name.

The problem is that I need the to know in each parameter they are. Because I need to draw some detail lines connecting them.

Not super sure what you are asking. Can you elaborate a little bit?
