Design Pattern: Simple State Machine (e.g. Time Of Day)

I still need a rule of some sort that updates the state of the (fixed) items, preferably once at the start of the day. I suppose that has to run daily to update the states with the correct date/time. But I think I can figure that out with ZonedDateTime, as I already did with the original rule.

Only the time has to be right. The JavaScript and Python rule will automatically move the date time to today for you.

If you are running OH 3, see OH 3 Examples: How to boot strap the state of an Item. You can define a card that lets you enter the DateTime from the UI. Then you can change it later without messing with Rules.

Of course you can do it with a rule too, but that’s not the only nor even the best way.
