@mike - Have been having fun playing around with finite state machines. Wanted to post an image of my simple sequence I've done to handle timed lighting controls based on home/away + guests.
I am using the "node-red-contrib-finite-state-machine" node vs "node-red-contrib-state-machine" node - I kinda like the ability to code in the transitions via JSON. Also note - I left out the actual light control part. For that I have separate sublows for each state and am using the "node-red-contrib-presence-faker" node to control timing/on/off etc...
As an aside - I'm a really "fascinating" and "interesting" guy apparently at least according to my wife.
