eWON Flexy supports MQTT for data acquisition

The IIoT gateway, eWON Flexy from HMS Industrial Networks now supports Message Queue Telemetry Transport (MQTT) protocol - a simple and lightweight messaging protocol aimed at minimising network traffic and device resource requirements. This includes all models including the new Flexy 205.

Initially created in 1999 to help oil and gas distribution firms control their pipelines effectively, MQTT has recently seen increased popularity because of the exponential growth of the Internet of Things (IoT) and the need to facilitate communication between low-powered smart devices.

MQTT is essentially a publish/subscribe protocol aimed specifically at low-powered embedded devices. MQTT targets low-powered embedded device environments where resources are scarce.

One of the upsides of using the MQTT protocol with eWON Flexy includes the ability to resume operations from any breakpoint without data losses. In addition, during network interruptions, data can be buffered until network communication is resumed and a client device reads the data. This not only prevents data loss, but also allows customers to manage the information flow to network nodes.

Designed to facilitate the transmission of large volumes of data to numerous servers and client devices constrained by low bandwidth, high latency, or unreliable networks, MQTT is suitable for dynamic communication environments. As the name indicates, the main purpose of the MQTT protocol is telemetry, also known as remote monitoring.

Several eWON Flexy users have already seen the benefits of this protocol and started to integrate it into their projects. One of them, W2W Solutions shares with us how they extend the life of their customer´s transformer using MQTT.
