This object carries the average data value across all elements within a SmartOffice sensor or actor group, expressed as a text string, when that group's readings change. It gives an admin a quick summary metric for a whole group rather than requiring them to poll each individual sensor, useful for spotting an aggregate shift like average temperature or occupancy. It's sent together with g6TrapObjTotalValue and g6TrapObjOfficeGroupName in the g6TrapSensorGroupChange and g6TrapActorGroupChanged notifications.
