  1. Get your personal access token

  2. Get your Device ID

    • In ThingsBoard, go to Devices, select your device, and click Copy device id

Get Device ID

  1. Perform the following curl command in your command prompt:

curl -v -X GET http://variot.ece.drexel.edu:8080/api/plugins/telemetry/DEVICE/<DEVICE ID>/values/timeseries?keys=<TELEMETRY FIELDS> --header "Content-Type:application/json" --header "X-Authorization:Bearer <PERSONAL ACCESS TOKEN>"

Where:

  • DEVICE ID is the Device ID you received in Step 2

  • TELEMETRY FIELDS are the telemetry fields you wish to receive in the form key1,key2,key3

  • PERSONAL ACCESS TOKEN is the token you received in Step 1

The response should look something like this:

{"<KEY>":[{"ts":1649704161368,"value":"425.534"}]}
