In this chapter, we have seen how to work with Google IoT Core as well as how to set up a device and subscribe to the state topic. We have seen how a client can subscribe to this topic and receive the data in real time.

Next, we used Google Cloud Functions to index the data from the state topic into BigQuery and from there we used Google Data Studio to visualize the data.

This concludes our exploration of Google IoT Core and how we can use Google Cloud Platform for IoT.

In the next chapter, we are going to look at the IBM Watson IoT platform.
