Connect it to Cloud Studio IoT

  1. 1

    Register the device in your network server

    Add it to The Things Stack, ChirpStack, Actility ThingPark or LORIOT with its DevEUI, JoinEUI and AppKey and the frequency plan of your region.

  2. 2

    Apply the decoder

    In The Things Stack, pick the model from the device repository and its decoder is applied for you. In ChirpStack v4, paste the official decoder as the device profile's JavaScript codec.

  3. 3

    Connect the network server to Cloud Studio IoT

    Set up the integration once per network server; every device registered there then reaches Cloud Studio IoT with its decoded values.

  4. 4

    Build dashboards and alarms

    The decoded fields become device variables for dashboards, alarms by email or SMS, and scheduled reports.
