See for example: > [@Design Pattern: Associated Items](https://community.openhab.org/t/design-pattern-associated-items/15790): > > Edit: Updates for OH 4 Please see [Design Pattern: What is a Design Pattern and How Do I Use Them](https://community.openhab.org/t/design-pattern-what-is-a-design-pattern-and-how-do-i-use-them/40319) for how to read and use DPs. Problem Statement Often one will have a number of separate Items which are all related to each other in some way. For example, one might have a Contact on a door and a DateTime to represent when the last time the door was opened. This is easy enough to keep track of if there are only one or two such Items, but if one has a lot of similar Items or is using a lot of gener… > [@Design Pattern: Working with Groups in Rules](https://community.openhab.org/t/design-pattern-working-with-groups-in-rules/20512): > > Edit: Updates for OH 4, inclusion of JS Scripting and Blockly examples, removed the doors example as it’s superfluous.

For example, filter down to just those members that are ON, get a list of the labels of those Items that are NULL, etc. Concept T… --- _[View the full topic](https://community.openhab.org/t/possibility-to-eliminate-simple-rules/88002)._
