MQTT
The MQTT protocol has been around for over 20 years now. And yet, especially today, it is used in a state-of-the-art area: the Industrial Internet of Things (IIoT) and the Internet of Things (IoT). MQTT is an open messaging protocol for machine-to-machine (M2M) communication that enables the transmission of telemetry data (messages) between devices.
MQTT is the transport of a wide variety of and arbitrarily formatted data. The MQTT protocol is simple and easy to process. As a straightforward and flexible protocol, MQTT is perfectly suited for IoT and Industrial IoT (IIoT).

MQTT and IoT
MQTT devices from ESERA are suitable for many IoT (Internet of Things) and IIoT (Industrial Internet of Things) applications.
As IoT and IIoT become increasingly important and there are more and more products and solutions on the market, MQTT is also playing an increasingly important role here.
MQTT acts as a publish-subscribe network protocol that transports messages between IOT and IIOT devices. As a rule, the MQTT protocol runs over TCP/IP.
