I am using hono to get IoT Data to my Jhipster-Ionic Application. How to a) send http get request to hono api, to fetch data and show it on my echarts dashboard. b) How do i send commands back to Hono using my application to control my IoT devices? c) how do i send hono data into postgres database (my application database) for showing historic data). THANKS

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)
