Start the broker You would need a Kafka broker. Admin client can't establish the connection to bootstrap server. The Micronaut producer gets the Sense Hat humidity, pressure, and temperature values and sends it to a Kafka topic. There are some ways how to make SmallRye Reactive Messaging a bit more dynamic (from top of my head, I remember that on the producer side, you can configure one channel and set the target topic through message metadata; not sure if there's something similar on consumer side), but you can always just use the Apache Kafka client directly (`io.quarkus:quarkus-kafka-client`) and just ignore . Finally, we may integrate our application with Kafka topics using annotations from the Quarkus Kafka extension. Understanding Non-Key Joins With the Quarkus Extension for Kafka Streams.
