[Deprecated] Design Pattern: Time Of Day

[Edit] Adde link to Time of Day State Machine For years now I’ve let this Design Pattern post get out of hand so I’m going to rein it in a bit now. It’s really expanded away from what it’s originally intended to be (i.e. a way to illustrate how to code a time based state machine) into a thread that is mostly about the example, Time of Day. It’s partially my fault for naming the thread “Time of Day”. But there are better alternatives for Time of Day in specific and time based state machines in g…

Instead of using “MORNING”, use “Good Morning” for the state.

Alternatively you can use the sun angle channel from Astro and set the phrase based on ho high up the sun is instead of wall clock time.

The key using time will be along the lines of:

var time = "Good Night"
if(now.isAfter(now.plusDays(1).minusHours(24-6)) time = "Good Morning"
if(now.isAfter(now.plusDays(1).minusHours(24-11)) time = "Good Afternoon"
if(now.isAfter(now.plusDays(1).minusHours(24-18)) time = "Good Evening"

Why the plusDays minusHours 24-x? To handle daylight savings.

Then just trigger the rule to run at system started and at those times and you are good to go.

It’s just a simplified version of the ToD DP.
