dc-square Releases HiveMQ 4 IoT Messaging Platform

By Ken Briodagh December 13, 2018

dc-square, the creator of HiveMQ, has announced the availability of HiveMQ 4, the new release of the popular enterprise MQTT messaging platform used by companies building IoT applications. HiveMQ 4 is designed to deliver support for the new MQTT 5 specification making it possible to build more reliable and scalable IoT applications. The new release also introduces the HiveMQ Marketplace and extension framework that allows customers to easily integrate HiveMQ and MQTT messages into their existing enterprise systems.

The new HiveMQ 4 release expands on the core services it provides for moving data between connected devices and enterprise systems. Based on the MQTT protocol, HiveMQ 4 now supports the new MQTT 5 specification. The new MQTT 5 features now supported in HiveMQ include:

  • MQTT payload format descriptions, including content type of format indicator which makes it easier to integrate MQTT messages with enterprise systems
  • Shared subscriptions of MQTT messages makes it possible to create scalable enterprise MQTT client services.
  • User properties can now be added to MQTT messages so it is now possible to extend the MQTT protocol to fit the business needs of an IoT application.
  • Session and Message expiry makes it easier to develop IoT applications that exchange data with limited lifetime and usefulness, so the overall system is more reliable and scalable.
  • Negative Acknowledgements allows an MQTT broker to inform a client why a connection has been broken. This allows the client to take corrective action to reconnect with the broker.

“HiveMQ’s support for MQTT 5 is an important step for our customers who need to deploy business critical applications,” said Dominik Obermaier, CTO, dc-square. “MQTT 5 addresses some of the shortcomings in the MQTT protocol that made it difficult to scale a reliable MQTT based system. HiveMQ 4 has implemented all these new features and we are proud to have a 100% complaint MQTT implementation. Our customers can depend on HiveMQ to provide a fast, reliable and efficient way to use MQTT to build IoT applications.”

HiveMQ 4 also introduces a new open API and HiveMQ Marketplace to make it easier to integrate HiveMQ into existing enterprise systems. The new open API allows developers to create extensions that integrate HiveMQ MQTT messages with existing enterprise systems, including databases, messaging systems, stream processing, and authentication systems. The HiveMQ Marketplace allows customers to gain access to pre-built extensions from dc-square. In the future it is expected the HiveMQ community will contribute additional extensions to the HiveMQ Marketplace.

“The new Winterhalter UC Series uses HiveMQ to connect our commercial dishwashers,” said Benjamin Köb, Head of Digital Products and Services, Winterhalter. “We needed a solution to efficiently connect our dishwasher with our backend, no matter if it is connected via cable, wifi or even our 3G modems. HiveMQ provided that infrastructure that we needed to be successful. The MQTT lightweight protocol was ideally suited for our requirements to move data from dishwasher to our backend.”


The IoT Evolution Expo, and collocated events, IoT Evolution Health, LPWAN Expo, The Smart City Event, and IIoT Conference, will take place Jan. 29 to Feb 1 in Ft. Lauderdale, Florida. Visit IoTEvolutionExpo.com to register now.
