Device type: Grouping devices by the type of device, such as temperature sensors, cameras, or actuators, can be useful for managing and monitoring devices that have similar functionalities.
Device location: Grouping devices by their physical location, such as by floor, building, or city, can be useful for monitoring and managing devices in specific locations.
Device role: Grouping devices by the role they play in the overall solution, such as gateways, edge devices, or cloud devices, can be useful for managing devices with different functionalities and responsibilities.
Device ownership: Grouping devices by the entity that owns them, such as by department, company, or customer, can be useful for managing and monitoring devices that are owned by different parties.
