@bptworld - just set this up to flash lights as a part of a couple laundry rules I created quite a while ago. (circa B.E.E. Before Event Engine. 
)
Anyway, I have flashers set up for two different lights I want to flash when the laundry is done, Right now I have it set up so that the flasher children are stand-alone, and triggered by a virtual switch. I turn on the virtual switch in the rule when I want the two lights to flash.
Just wanted to ask if this is the "right" way to connect things up, or if there is a simpler/more efficient way to call the two flasher children from the rule.
Thanks, as always, for the app!
