Case Study: Daimler Relies Upon HiveMQ During Automotive Manufacturing


Learn how and why Daimler uses HiveMQ to manage information flow between vehicle diagnostics system test devices on the factory floor and server-side enterprise IT systems

Daimler’s non-stop manufacturing process requires reliable software infrastructure

Vehicle diagnostics systems are a critical part of the manufacturing process. If vehicle diagnostics systems go down for more than 10 minutes, the manufacturing process may stop. This is because vehicle diagnostics systems fulfill some core functionality in the manufacturing process, such as calibrating sensors controlled by an engine control unit, flashing new firmware, personalizing keys to the car and testing to make sure each engine control unit works properly. Vehicle diagnostics systems also generate the test documentation required for the regulatory requirements of the destination country for the vehicle.

HiveMQ ensures reliable messaging to and from the factory floor

Daimler selected HiveMQ’s MQTT (message queuing telemetry transport) broker since they needed a reliable message platform to operate in their factories. Vehicle diagnostics system test devices move around the factory floor and network access is not always guaranteed since there may be some blind spots in the factory. Daimler saw the benefits of MQTT’s ability to provide continuous data exchange between vehicle diagnostics system test devices on the factory floor and server-side enterprise IT systems even when network connectivity is poor.

Key challenge:

  • Vehicle diagnostics systems are a critical part of the manufacturing process and can not go down
  • To avoid downtime, a reliable messaging platform for factory to cloud connectivity is required


  • Daimler rolled out HiveMQ’s MQTT broker to 24 factories around the world
  • 10,000 testing devices connected
  • Generating 470 million messages/month 

We have been running the VDS using HiveMQ for 4 years and the HiveMQ broker has not gone down. It is rock solid, completely reliable.
