Things
In IoT Platform there are 4 entities in the Thing management world:
Group
An entity in our hierarchy representation, a group can have one parent group allowing the customers to create hierarchy trees, and devices can be members in multiple groups. So you can have groups that delineate a spatial hierarchy, but also have a hierarchy based on devices types (All devices that are HVACS, and then sub groups based on manufacturers).
Digital Twin
A representation in IoT Platform of a specific logical entity, for example this could be “Floor 1”, “North Beach Parking Lot”. A digital twin is an enhanced group, meaning that it has the capabilities of groups in terms of hierarchy, and in addition it has readings, properties and calendars. A group associated with a group template is considered to be a digital twin.
Device
A representation in IoT Platform of a physical entity or sensor in the real world, for example this could be a specific temperature sensor or a field gateway. When viewing the device in IoT Platform you can see the readings it has sent, the values currently set, and other information about the device.
Virtual Device
A Device in IoT Platform that can be configured (through the product) to have fake data sent periodically from within IoT Platform .
