A group determines which lines and sensors in the system a user can view. Each group is granted access to certain lines or sensors. The user cannot see lines and sensors outside of the group in the Factbird system.
At the same time, a group represents the link between a role and a user, as each group is assigned to a specific role, i.e., all members of this group have the same role permissions on the added lines and sensors. Typically, groups are used to separate countries, locations, or even different location-internal sections from each other.
