sensorIoTenheter

sensorIoTenheter is a framework and architectural approach for integrating heterogeneous sensor networks and Internet of Things endpoints. It aims to provide a unified method for collecting, normalizing, and exchanging data across devices, networks, and cloud services, enabling interoperable applications and analytics.

Key architectural elements include: device adapters to translate device data into a common model; a semantic layer for measurements, units, timestamps, and provenance; an interoperability layer that supports MQTT, CoAP, HTTP, and gateway-to-cloud messaging; and an analytics and policy layer for storage, processing, and access control.

Edge gateways provide local data fusion and privacy-preserving preprocessing, while cloud services offer long-term storage, cross-domain analytics, and orchestration. Security is addressed via device identity management, mutual TLS, token-based authorization, and role-based access controls. Data formats commonly used are JSON, SenML, and CBOR.

Key features include cross-network device discovery, semantic metadata management, time-series data organization, data normalization, event-driven rules, and near real-time dashboards. The framework supports batch and streaming workloads and is accompanied by open reference implementations under permissive licenses.

Applications span smart cities, industrial automation, building management, environmental monitoring, agriculture, and healthcare devices, where sensorIoTenheter enables interoperable data pipelines and unified governance across heterogeneous device fleets.

Historical notes: The concept of sensorIoTenheter was introduced in 2024 by a community consortium focused on IoT interoperability. Since then, several prototype implementations and testbeds have explored its architecture, with ongoing work on governance, security, and performance benchmarks.
