Raspberry Pi - Getting started with MQTT

WHAT IS MQTT? MQTT (Message Queue Telemetry Transport) is a simple and ‘lightweight’ way for internet-connected devices to send each other messages. This is important for home-automation because devices need to send messages back and forth like ‘turn on the lights’ or ‘turn off the sprinklers.’ Devices using MQTT communicate by publishing data to topics. MQTT devices subscribe to a topic, and when data is published to that topic it is pushed to all the subscribers.
