GROUP

Reference to a group of devices whose aggregate power is constrained, given as either a power sensor ({"sensor": <id>}) or an asset ({"asset": <id>}) - exactly one of the two. The referenced sensor or asset should itself get its own flex-model entry defining the group’s power-capacity (hard constraint) and/or consumption-capacity/production-capacity (soft constraints with default breach prices). When the group is referenced by sensor, the group’s scheduled aggregate power is saved to that group sensor. When the group is referenced by asset (e.g. a sub-EMS asset in the tree), the group entry defines no power sensor of its own; the group’s aggregate power is instead saved via that entry’s own consumption and/or production output sensors, following the usual output-sensor conventions.
