AWS IoT Core provides a convenient way to connect your IoT devices like ESP32 to the cloud. Typically MQTT protocol is used for that.
Let’s suppose everything is setup on AWS IoT side and you can see messages from IoT Test console. Next we would like to transfer those MQTT messages to some other service that can actually do something useful with them. AWS SQS queues can be used for that.
Let’s create a rule that triggers a Lambda function every time if something is sent to a topic floor/1/room/3/temperature. Actually let’s receive all temperatures from all floors and rooms.
