Sensate IoT is an opensource Internet of Things data broker. It enables simplified management of devices, data and data analysis through a well documented RESTful API. The backend scales extremely well, both vertically and horizontally. High availability and performance is ensured through clever use of caches and document stores.

Sensors can communicate in one of two ways with the sensate servers:

• MQTT (with or without TLS)
• HTTP gateway

In both cases, a pseudo model in JSON format is expected by the Sensate backend:

{
  "longitude":4.79691,
  "latitude":51.58701,
  "timestamp": "2020-10-08T06:30:34.1115Z",
  "sensorId":"5efdaa9f282963000157823f",
  "secret":"$23c00474e37e82468518699c27411831214a818653d70fe2ee9bd80eea59f418==",
  "data":{
    "x":{
      "value":9.79635,
      "unit":"m/s2",
      "precision":0.01,
      "accuracy":0.5
    },
    "y":{
      "value":12.67006,
      "unit":"m/s2",
      "precision":0.01,
      "accuracy":0.5
    },
    "z":{
      "value":65.89981,
      "unit":"m/s2",
      "precision":0.01,
      "accuracy":0.5
    }
  }
}

On the root object the follow property's are required:

• sensorId;
• secret;
• data.

If the sensor doesn't provide a value for timestamp, the platform will assign the current timestamp to the measurment.

The data property is an object of data points. At least one datapoint is required and the value is the only required datapoint property. Please note that the array length of data isn't limited to three. A measurement can contain anywhere between 1 and 25 data points.

Contributing to the Sensate IoT project is very much appriciated. Please note that writing code isn't the only way to contribute:

• You can submit bug reports on the issue system;
• You can submit feature requests on the same issue system;
• You can pick up existing issue's and implement them;
• You can help design features by replying on existing issue's.

When you pick up an existing issue in order to resolve it, please let us know. This will prevent two people working on the same issue. If you are creating a new issue please use one of the supplied github templates. Sections that are not applicable should be removed. More information about contributing to Sensate IoT can be found in CONTRIBUTING.md.
