Executing a subroutine

from an automation, either search for the "execute subroutine" action or find it under the system utility category in the system app here it's generally easier to just search for "subr" after choosing "find an action" select the subroutine to use from the list then click the fetch button then configure the input fields for the subroutine and save subsequent actions can access the subroutine's output fields in the graphical automation history you can examine the subroutine's input and output click on either the subroutine or the details button to drill down and examine the processing performed by the subroutine when the parent automation's history is searched, any subroutines it uses are also searched and included in the search results
