Things SDK API

Developing “Things” which are market-ready (with cloud support) has been a challenge for most of the companies and individual developers. The SmartThings™(ST) Things SDK API helps you to create new IoT devices easily.

Following are the two core components for creating a new device:

  • ST Things JSON Configuration files (master.json and resource.json)

    For more information on the configuration file details, see Device Definition.

  • Application logic and user interaction

    For more information on using the ST Things SDK API, see API Usage.

The ST Things SDK provides you an easy and configurable option to build and deploy your own devices quickly:

  • The ST Things SDK provides JSON-based things definition, which:
    • Defines device and platform information.
    • Defines resources that the thing is supporting.
    • Defines an easy-setup configuration.
  • The ST Things SDK provides spec-agnostic APIs, which:
    • Hide the interface and resource type details in a request data.
    • Divide a collection resource request into single resource requests.
    • Provide the “property_key” in case of the GET request.

The ST Things SDK API provides the following benefits for you:

  • Supports pin-based and UserConfirm(Certificate)-based OTM in EasySetup.
  • Provides a JSON-based device/resource definition method in two file, master.json and resource.json:
  • Resources that are defined in resource.json file are made internally.
  • Provides easy APIs to handle requests and responses:
    • Supports request methods: GET and POST.
    • You only need to make a representation (bundle of property values) for a response.
    • You do not need to handle interfaces, as they are handled internally.
    • The request to a collection resource is divided into individual requests to single resources.
  • Provides internally handled cloud setup (Sign-up or Sign-in or Sign-out or Resource publish to cloud).
  • Provides the following internally handled operations:
    • To respond to an Access Point List (APList) request from a client.
    • To start and stop softAP.
    • To connect to a target WiFi AP (Enroller).
    • To make the whole response data according to the interfaces (such as oic.if.baseline, oic.if.b, and oic.if.ll).
