Device Data

Device data represents the information your IoT devices send to TagoCore. Each piece of information is called a "data point" and follows a specific JSON structure that TagoCore can understand and process.

When your device sends data to TagoCore, the platform automatically validates each data point to ensure it follows the correct format. This validation helps prevent errors and ensures your data is properly stored.

All data points use the same JSON structure as the TagoIO Cloud platform:

{
  "origin": "61be276db205c10019e6a218",
  "variable": "temperature",
  "value": 100,
  "time": "2022-01-01T12:00:00Z",
  "unit": "F",
  "group": "123456",
  "metadata": {}
}

Key fields explained:

  • variable: What type of data this is (e.g., "temperature", "humidity")
  • value: The actual measurement or reading
  • time: When this data was recorded
  • unit: The measurement unit (e.g., "°C", "%", "ppm")

For detailed specifications, see the API Overview.

Sending Data​

TagoCore uses the same communication standards as TagoIO Cloud, making it easy to migrate or integrate existing solutions.

To send data from your device to TagoCore:

  1. Make an HTTP POST request to the /data endpoint
  2. Include your Device Token in the token header for authentication
  3. Send your data in the JSON format shown above

For complete parameter details and examples, check the API documentation.

Retrieving Data​

You can access your device data in two ways:

Programmatic Access: Send a GET request to the /data endpoint using your Device Token in the header. This method gives you complete access to all data points with their full details.

Visual Overview: Visit the Data tab on your device's page in the TagoCore interface. This provides a quick overview of all variables and their current values without needing to make API calls.
