What is MQTT?

MQTT stands for MQ Telemetry Transport and is a lightweight and low bandwidth ‘publish-subscribe’ network protocol for transporting messages between devices, usually over TCP/IP. MQTT is a commonly used communications protocol for Machine-2-Machine (M2M), Internet of Things (IoT) and Industrial Internet of Things (IIoT) devices including environment monitors, and mobile applications, allowing them to communicate and report their data to a master station i.e. a Cloud-based portal or in-house server or computer running the appropriate monitoring software.

MQTT-flex is a NETIO extension of the standard MQTT protocol. The extension uses a configuration text file to specify the MQTT message structure, the MQTT broker address where messages are sent, and the periodicity. MQTT-flex is designed to work with Netio smart power monitoring & control and remote reboot devices.
