How to stream IoT & telematics data to Google IoT Cloud?

Ingest telematics events from flespi to the Google IoT Cloud using Google Pub/Sub.

Google Cloud announced that it’s shutting down its IoT Core service on August 16, 2023. The alternative for exchanging the data with the Google ecosystem is the Google Pub/Sub service destined to establish asynchronous communication between applications and solutions. With flespi you can publish telemetry data to Google Pub/Sub and then subscribe to the appropriate topics to get that data in the desired destinations.

  1. Create a project in Google Console. You will need to paste the project ID into the stream configuration later.
    google cloud console project id

  2. Create appropriate topics.

  3. Create a flespi stream to publish messages to these topics. Specify your Google project ID (from step 1), service email (learn how to create a service account), and the private key for IAM authorization in the stream configuration:
    create flespi stream to google pub sub
    Note: you can also specify a list of parameters (or all parameters) to be added as message attributes into the message.

  4. Subscribe the stream to devices to forward data from:
    subscribe stream to devices

  5. Make sure the stream started sending messages:
    check logs flespi stream

  6. Subscribe to the topics from your target applications to get the updates instantly.
