Problem Statement One powerful way to consolidate code in rules is to use array/list manipulation operations on the members of a Group.

And realize that the postUpdate and sendCommand actions will take a name of an Item as the first argument so if you can construct the name of the Item programatically in your rule you can send it commands or post updates to it.
