IoT device model

Concepts

Concept	Meaning
Thing/entity	A physical device, virtual device, service, or application
Network identity	Address used to communicate, normally an XMPP JID
Conceptual identity	Persistent identity of the thing independent of a connection
Data source	A named source tree exposed by a concentrator
Node	A physical or virtual item inside a data source
Partition	Optional discriminator when node IDs are reused in separate partitions
Sensor	Exposes read-only fields over time
Actuator	Exposes writable, typed control parameters/actions
Concentrator	One network identity that contains many sources/nodes

A standalone device uses its JID as the address for sensor/control operations. A concentrator operation adds source ID, node ID, and optional partition.

Capability discovery

Query capabilities before calling an interface. A concentrator can expose sensor data, control, node management, commands, queries, events, and troubleshooting features independently.

Extended addressing

Use this tuple as a stable node address inside a concentrator:

(Concentrator JID, Source ID, Node ID, optional Partition)

Node display names and positions are not identifiers. Persist the full tuple and be prepared for a node-moved event.

Harmonized interfaces

Basic sensor and control models enable human UIs. Harmonized interfaces add agreed machine semantics for a use case. A device advertises the qualified interface identifiers it supports, allowing cross-vendor applications to interpret data without model-specific code.

Bridge pattern

A protocol bridge maps Modbus, MQTT, HTTP, GPIO, files, or another local technology into this model:

Protocol device -> bridge node -> sensor/control interface -> XMPP federation

Keep protocol-specific identifiers as metadata, while exposing stable Neuro source/node IDs to clients.
