Sub-device

A sub-device is a device that cannot connect to the platform on its own and is reached through a gateway. The gateway owns and manages it.

• Its device type is "sub-device (gateway-managed)" and it has an owning gateway.
• Telemetry, presence and commands flow via the gateway's northbound connection.
• It may have at most one bound connector; the connector column on the device list shows its reported state.

A direct device is the opposite case: it authenticates and connects to the platform directly.
