Overview
ISO/IEC 30118-18:2021 - "Information technology - Open Connectivity Foundation (OCF) Specification - Part 18: OCF resource to Z‑Wave mapping specification" provides a formal, machine-readable mapping between Z‑Wave device models/command classes and OCF (Open Connectivity Foundation) resources. The standard defines how Z‑Wave servers (devices) can be exposed and controlled by OCF clients over IP-based IoT networks, enabling secure, interoperable smart‑home and commercial IoT deployments.
Keywords: ISO/IEC 30118-18:2021, OCF, Z‑Wave, mapping, interoperability, IoT, smart home, bridging
Key topics and technical requirements
- Interworking approach and theory of operation: Describes bridging concepts and how an OCF–Z‑Wave bridge translates between the two ecosystems.
- Mapping syntax and conventions: Defines notation for property naming, value assignment, ranges, arrays, conditional/default mapping, and method invocation used in mappings.
- Z‑Wave translation and bridging requirements: Requirements for exposing Z‑Wave servers to OCF clients, operational scenarios, and Z‑Wave specific constraints for bridging functions.
- Device type mapping: Rules for mapping Z‑Wave device types to OCF device types to maintain consistent device models across ecosystems.
- Resource to command class mapping: Detailed correspondences between OCF resources and Z‑Wave command classes (for example: Battery, Binary Switch, Door Lock, Multilevel Sensor, Multilevel Switch, Notification, User Code).
- Detailed mapping APIs and derived models: Concrete API-level mappings, property definitions and derived model definitions for key command classes to enable implementation and testing.
Practical applications and who uses this standard
- Gateway and bridge developers: Implement OCF–Z‑Wave bridges to expose Z‑Wave devices on IP networks and unify control across ecosystems.
- IoT platform integrators & smart‑home vendors: Ensure consistent device models and control semantics when integrating Z‑Wave products with OCF-based platforms.
- Device manufacturers: Map Z‑Wave command classes to OCF resources to simplify cross‑ecosystem compatibility and reduce integration costs.
- Security architects and installers: Use OCF bridging with reference to ISO/IEC 30118-2 (Security) to deploy more secure device discovery, onboarding and control.
- Test labs and certification bodies: Validate conformance of bridges and implementations against the documented mappings and derived models.
Common use cases include exposing battery status, binary/multilevel switches, door locks, environmental sensors (CO2, CO, smoke, water flow), notifications and user codes from Z‑Wave devices to OCF clients for unified monitoring, control and automation.
