Concepts

Haltian IoT is a cloud-based IoT platform providing device connectivity, data ingestion, and API services for wireless sensor networks. The platform implements a multi-protocol architecture supporting Wirepas mesh networks, MQTT device connectivity, and third-party integrations, with data accessible through GraphQL, MQTT, and Parquet-based APIs.

The platform manages wireless sensor deployments including occupancy detectors, environmental monitors, parking sensors, and people counters. Data flows through three complementary interfaces: a GraphQL Service API for device management and queries, an MQTT Stream API for real-time telemetry streaming, and a Parquet-based Data API for bulk export to data lakes and analytics platforms. The architecture scales from single-site deployments to multi-organization, multi-tenant environments with hierarchical access control.

Native integrations enable direct data flow to enterprise platforms. The Microsoft Places integration exposes occupancy data through Microsoft Graph API, enabling Teams room availability and Outlook desk booking without middleware. Similar integration patterns support ThingsBoard, Azure IoT Hub, and custom analytics pipelines.

The platform enforces privacy-by-design at the sensor level: all devices use passive infrared, radar, or laser-based detection — no image capture or biometric data collection. Role-based access control (RBAC) with organizational scoping ensures data segregation across tenants, meeting GDPR and enterprise compliance requirements for anonymous occupancy monitoring.
