AWS IoT Core was the glue between the ESP32 sensor and AVS. We created a device shadow on AWS IoT Core to hold the state of the ESP32 sensor. We have seen that all data exchanges are in the form of JSON documents and the document structures are available in the online Alexa documentation as the main reference. When we look at the products on the market, we can understand that voice interfaces are becoming more common among IoT products. Therefore, it is important for us to learn how to use voice services and integrate them within our solutions.
