MQTT (originally an initialism of MQ Telemetry Transport [a]) is a lightweight, publish–subscribe, machine-to-machine network protocol for message queue/message queuing service.

Node-RED has gained traction in the industrial internet of things (IIoT) and edge computing sectors. [8] [9] [10] Node-RED's open-source nature and large community have led to the creation of over 4000 connectors [11] supporting a wide range of data sources and protocols such as Modbus, OPC-UA, Siemens S7, and MQTT.
Updates to the standard are planned to occur biannually. [28]Version 1.0 of the specification was published on 4 October 2022. [29] It introduced support for lighting products (such as mains power plugs, electric lights and switches), door locks, thermostats and heating, ventilation, and air conditioning controllers, blinds and shades, home security sensors (such as door, window and motion ...
ZeroMQ (also spelled ØMQ, 0MQ or ZMQ) is an asynchronous messaging library, aimed at use in distributed or concurrent applications. It provides a message queue, but unlike message-oriented middleware, a ZeroMQ system can run without a dedicated message broker; the zero in the name is for zero broker. [3]
