Making Decisions Based on Time of Day

but in Java 8 and OH2

Joda is still available so all the old 1.x Joda code examples should work just fine. Only OH does the imports for you so you no longer need to import from org.joda to have access to the Joda classes. But that doesn’t make them unavailable.

A combination is also possible

That is actually illustrated in the Time of Day DP I linked to above. It has some times defined by cron triggers and others based on events, Astro events in this case. One could easily add additional events and criteria if needed.

regularly check if a door has been left open, and how long

Timers and/or Design Pattern: Expire Binding Based Timers is a better approach to this over a cron triggered polling rule.

A couple of examples:

Design Pattern: Motion Sensor Timer

Edit: Updates for OH 4 Please see Design Pattern: What is a Design Pattern and How Do I Use Them for details on how to use DPs. Problem Statement Many motion detectors only report ON when they detect motion but do not send a corresponding OFF after no motion has been detected after a period of time. In addition, often one wants to control a device like a light for a certain period after the last motion is seen, not after the motion sensor goes to OFF. Therefore one needs to keep a Contact OPEN…

[Deprecated] Design Patterns: Generic Is Alive

There is now a Rule Template on the marketplace to implement this for you. See below for instructions on how to set it up. Please see Design Pattern: What is a Design Pattern and How Do I Use Them for a description of what Design Patterns are and how to use them. Problem Statement Many sensors report status to openHAB periodically (e.g. temperature sensor) or unpredictably (e.g. motion sensors) and a subset of these sensors do not have a built in way for openHAB to query whether or not they a…

One reason why I came up with the Time of Day Design Pattern is because it lets me centralize all of those Time cron triggers and if(now.isBefore tests and make them into events to drive the rest of the automation.
