OpenIoE is an Open-source middleware platform for building, managing, and integrating connected products with the Internet of Everything. It enables you to subscribe to data streams and get data from the sensors and store them. The application was generated using JHipster application generator.
docker-compose up -d
docker-compose stop
in the same folder as abovedocker-compose logs [CONTAINER]
(ex: ioe-app)./artemis run
in order to start the broker.sudo ./gradlew
to start running the application.The sensor data can be published using rest end point and message broker with MQTT support. Both methods accept the payload as JSON. An example for publishing data with rest endpoint using curl command is
curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' --header 'Authorization: Bearer <access_token>' -d '{
"data": "24",
"description": "test",
"sensorId": 1,
"timestamp": "2017-03-19T09:47:44.526Z",
"topic" : "gps"
}' 'http://127.0.0.1:8080/api/sensors/{id}'
The user can also publish data using MQTT protocol with MQTT client applications by sending the data of the following form to the topic 'gps'.
"data": "24",
"description": "test",
"sensorId": 1,
"timestamp": "2017-03-19T09:47:44.526Z"
The user can subscribe to topics defined for subscription entity using MQTT client applications by providing the topic name as gps. Whenever a new data is published, it will be stored in Cassandra and can be received by the user.
Data can be stored via the REST endpoint and the message broker. Both methods accept the payload as JSON.
An example is
{"sensorId":1,"data":"24","description":"test","timestamp":"2016-07-30T21:29:34+02:00"}
Using the REST end point data can be retreived.
http://127.0.0.1:8080/api/sensors/1/data
where 1 is the sensor id
http://127.0.0.1:8080/api/sensors/1/data?dates=2016-07-30,2016-07-2
where multiple dates can be specified
