Introduction

Prior to Rifidi 3.1 (coming Fall 2014) Edge Messaging is available through ActiveMQ/JMS Interface. Starting in 3.1 Edge Messaging is now accessible though MQTT (Lightweight IoT Messaging Protocol through leveraging Moquette-mqtt plugin.

This now enables Rifidi Applications to publish events (captured via Rifidi Services for example Readzone Montoring, Stables Set) to a lightweight MQTT messaging queue
