HiveMQ

HiveMQ Community Edition is a lightweight MQTT broker that boots with anonymous access. It is the simplest broker in the catalog: no credentials to manage, just an MQTT listener.

Preset ports​

  • HIVEMQ_MQTT_PORT=1883: host port for the MQTT listener (the standard MQTT port).

HiveMQ CE accepts anonymous connections out of the box, so there is no preset password.

Post-setup​

  • mqtt-engine-connection: connecting a gateway needs the Cirrus Link MQTT Engine or Transmission module plus an MQTT server endpoint pointed at the broker, configured once the stack is up.
