Oooohhh - Finite State Machine (FSM) - the love of my life.
I think you might be right - the code lends itself to being coded as an FSM (either using pure JavaScript or the Node-RED FSM node).

Finite State Machine (FSM) with delay

I was asked the other day about how to create a Finite State Machine (FSM) with different delays between various transitions. Here is a simple example, based on the UK traffic light sequence, that makes use of the msg.delay option in the Delay node. Here's a screenshot of the flow.
