Home and Building Electronic Systems (HBES)- Part -4-4 HBES IoT Point API prEN 50090-4-4

Scope

The Point API provides a mapping of HBES AL data to a RESTful resource model and CBOR/JSON based data representation that is used to communicate over IP. Using this API, a client can read/write values or can subscribe to Point events (e.g., switch on/off).
The HBES IoT Point API is based on the following building blocks:
1. Discovery
2. S-Mode Messaging
3. Point Read, Write and Publish/Subscribe
4. Security
This version of the HBES IoT Point API specification solely considers the use of CoAP as application protocol.
