Introduction

The Instathings API is organized around REST.

Our API has predictable resource-oriented URLs, accepts application/json request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs.

Authentication

Authentication follows the OAuth client_credentials flow, so it's intented for machine to machine (M2M) authentication.

Instathings API need to be enabled to retrieve a clientId and clientSecret in the Settings section of your project.

Once you have obtained clientId and clientSecret, you can use them to request the JSON Web Token (JWT) needed to authenticate Instathings API requests.

Get Authentication token

curl -XPOST \
-H "Content-type: application/json" \
-d '{ "clientId":"yourClientId", "clientSecret": "yourClientSecret"}' \
'https://yourProjectName.instathings.io/authentication/v1/oauth/token'

The above command returns JSON structured like this:

{
  "access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c",
}

POST /authentication/v1/oauth/token

This endpoint retrieves the authentication token.

Body Parameters

Parameter Required
clientId true
clientSecret true

Device

Device REST API service allows you to perform operations on a device resource.

Other than usual CRUD operations you can:

On-premise REST API

OP: Connection to HTTP web server

If the ON_PREMISE_ENABLED option is set to true a Web Server starts and you can send HTTP requests to its public API.

The base path of your server depends on the IP address of your gateway and the port the server is listening to

Example of base path for your server

http://localhost:1234
http://localhost:1234

OP: Get data for a specific device

curl "http://YourGatewayIpAddress:PORT/device/v1/devices/:deviceId/data?page=1&perPage=1&sort=-ts"

The above command returns JSON structured like this:

{
    "data": [{
        "_id": "5ec4ecdc11f6c352cf3f372e",
        "data": {
            "type": "data",
            "message": {
                "data": {
                    "relays": [{
                        "ison": false,
                        "has_timer": false,
                        "timer_remaining": 0,
                        "overpower": false
                    }],
                    "temperature": 30.82,
                    "overtemperature": false,
                    "ram_total": 50608,
                    "ram_free": 40304,

        "ts": "2020-05-20T08:39:55.995Z"
    }],
    "totalItems": 14
}

This endpoint retrieves ingested data sent by a specific device.

GET /device/v1/devices/:deviceId/data

Path Parameters

Parameter Required
deviceId true

Query Parameters

Parameter Required Description
start false date in ms, starting point from which retrieve data
end false date in ms, data sent after this moment are not returned in the response

On-premise Websocket API

Real-time notifications are exposed via websocket even when you're working on-premise.

socket.io is used behind the scene, we suggest to use a socket.io client for maximum compatibility.

Here are listed the event types you can receive:

OP: Connect to websocket

wscat -c 'ws://localhost:1234/socket.io/?EIO=3&transport=websocket'
const io = require('socket.io-client');
const socket = io('http://localhost:1234');

socket.on('connect', function (socket) {
  console.log('Connected!');
});

The websocket connection url is your server base url.

For instance: http://localhost:1234

 OP: Message encoding

Each message sent and received via the websocket channel is encoded in JSON format.

OP: data

The data event is emitted every time a device send data to the Gateway.

By registering a listener on this event you will receive an event regardless of the deviceId.

The response message contains the information sent by the device

The data event returns a JSON like this:

 {
     "deviceId": "a1234",
     "payload": {
        "temperature": 30.82,
        },
   "ts" : "2020-05-20T12:19:44.395Z",
    }

OP: data_deviceId

The data_deviceId event is emitted every time a device send data to the Gateway.

By registering a listener on this event you will be notified only when the device with id equal to deviceId sent its data.

The response message contains the information sent by the device

The data_deviceId event returns a JSON like this:

 {
        "temperature": 30.82,
 }

OP: status

The status event is sent every time a device sends its status. A device sends its status when a response is received from a Get device status by id.

The response message contains the following keys: * deviceId: the id of the device * payload: the information sent by the device * ts: timestamp of the event

The status event returns a JSON like this:

{
  "payload": {
        "temperature": 30.82,
    },
  "deviceId": "9s9WdonY9",
  "ts" : "2020-05-20T12:19:44.395Z"
}

OP: status_deviceId

The event status_deviceId is sent every time a device sends its status. A device sends its status when a response is received from a Get device status by id.

If you register a listener on this event you will be notified only when the device with id equal to deviceId sent its status.

The response message contains the information sent by the device

The status_deviceId event returns a JSON like this:

 {
     "temperature": 30.82
 }

OP: deviceId

The deviceId event collects all the events related to a single device.

The response message contains the following keys:

The deviceId event returns a JSON like this:

{
    "action": "data",
    "payload": { "temperature": 20.4 },
    "ts" : "2020-05-20T12:19:44.395Z",
}
