a) You can't. Hono writes the telemetry and event messages it receives from devices to Kafka topics. Applications that want to process the messages therefore need to create a corresponding Kafka Consumer an can then do with the data whatever they see fit. See https://www.eclipse.org/hono/docs/api/telemetry-kafka/#northbound-operations for details regarding the topic structure and message format. b) You can use Hono's (Kafka topic based) north bound Command & Control API for this. See https://www.eclipse.org/hono/docs/api/command-and-control-kafka/ c) see a)
