MQTT is the top choice of large companies worldwide for data exchange with constrained devices and server applications. You are just as likely to find MQTT connecting things in your living room, in a car as within a factory. The widespread adoption of MQTT led to the acceptance as an open OASIS and ISO standard. Today, MQTT is the absolute standard protocol for the Internet of Things worldwide.

In 2015, HiveMQ wrote the MQTT essentials blog series. A new article introducing the core concepts of MQTT was published every Monday - that was the beginning of the MQTT Monday. By explaining the features of the protocol and other essential information, our aim was to provide easy access to the subject. The idea was to make it easy to understand and implement MQTT quickly and successfully.

Five years later, our blog series is still very successful. That's why we want to make the MQTT content even more accessible. We are happy to announce that MQTT Monday is back - this time in video format. Every Monday, from now on, we will publish a short MQTT Essential video on our YouTube Channel. Our new series of videos will provide a basic understanding of the MQTT protocol and will familiarize everyone with the MQTT protocol without reading the full specification.

There's a lot going on in the MQTT world right now: With the release of MQTT 5, the most feature-rich update to the MQTT specification ever, new features such as session & message expiry intervals, improved client feedback & negative ACKs, payload format description, and many more, have been introduced. The industry initiative “Sparkplug” has evolved to define a common MQTT data specification to promote interoperability between device manufacturers and SCADA vendors. We believe this is just the beginning. Over the next few years, we expect continued massive growth of MQTT application in all industries, including manufacturing, automotive, critical infrastructure, logistics, smart cities, etc.

HiveMQ will continue to provide high-quality content that helps developers understand and adopt MQTT for their IoT applications. Keep watching our Youtube channel or subscribe to our newsletter to keep up to date on the latest news.
