Bosch IoT Suite

Devices via Bosch IoT Hub connection

This section describes the default pre-configured connection, which is established automatically by subscribing the Bosch IoT Suite for Asset Communication package.
In case you need to adjust it, find here some details of how it should be configured.

Bosch IoT Hub

  • Your instance is automatically pre-configured to be allowed to send messages to our cloud infrastructure.
    Bosch IoT Hub does not have a UI on its own, thus all relevant information is accessible via Bosch IoT Things Dashboard.

  • By default, the automatically created connection is named "Devices via Bosch IoT Hub".
    The connection is visible at the Bosch IoT Things Dashboard, see below.

Bosch IoT Things

Your instance is pre-configured to allow all messages from Hub to be routed and processed at Bosch IoT Things.

  1. Open the Connections tab to see the entries created automatically during the package booking process.

  2. Click the default connection to see its details.

  3. In the General section you see the new feature enabled.

  4. The Coordinates section is filled with the Hub credentials received at booking.

  5. In section Sources you will find the pre-configured topics:

    1. Source 1

      1. Addresses

        1. event/{{your-hub-service-tenant-ID}} and

        2. telemetry/{{your-hub-service-tenant-ID}}

      2. Authorization
        The authorization subject: integration:{{your-things-service-solution-ID}}:hub
        This entry can also be found in the default policy, which we create for you.

      3. Requested acknowledgements
        Filter: fn:filter(header:qos,'ne','0')

      4. Options
        The option to Enable Bosch IoT Hub/Things ID convention is checked by default and a strong prerequisite for the successful and secure communication between the two service layers.
        Thus, keep in mind that the device ID at the Hub will be identical with the thing ID at the Things service by default.
