This is one of the simplest ways to select Revit objects in Dynamo. Simply feed a Categories selection into this All Elements of Category node, and after the script is Run, those objects will be selected in the Dynamo session.

Dynamo Nodes 
Is there a way to select multiple categories? I want to be able to select Electrical Fixtures and Data Devices at the same time?
Hi Paul, using core nodes you could just use List.Create and merge two lists of elements that way.
