Today I stumbled upon a podcast interview on MQ Telemetry Transport, or MQTT, with Andy Piper from IBM. MQTT is an M2M/Internet of things connectivity protocol developed at IBM. Much of the podcast talks about how this technology is being used in home DIY sensor projects. MQTT is based on a “Publish and Subscribe” architecture and requires a Broker to handle the messaging. Although IBM have a few different MQTT Broker implementations, there is an open source implementation of the broker server called Mosquitto that looks worth experimenting with.
If that wasn’t enough to wet your appetite, Andy Stanford-Clark (also from IBM) gave a presentation called “The house that Twitters” which explains how he has used MQTT to create a number of interesting home sensor projects.
