This is a really good post - thank you! This will help me write state machines for OH.
Just an FYI: there is a GUI that amg0 wrote on top of the Vera interface that allows you to create the state diagram in the browser and add links and actions in it directly. Not only that, it is animated, so you can see the current state and see the value of the active timer if any. It would be really cool to get something like this for OH2 someday. Or does something like this already exist?
