This is the equivalent of openHAB's triggeringGroup, and it is only available on a member-of-group trigger.

Returns:

    The group item whose member had triggered this event. nil when the event wasn't triggered by a member-of-group trigger.

Since:

  • openHAB 4.0 for file-based rules

  • openHAB 4.1 for UI rules
