M2M home data interoperable management system based on MQTT

Wireless sensors networks have an enormous potential for measuring environmental parameters such as those found in building or residential scenarios. The range of available sensors is not only limited temperature, gas, humidity or presence detection, but even power grid analyser can be integrated. This work aims to develop a Home energy management system for a residential scenario or nanogrid. Inside this nanogrid and using short term power availability together with demand response techniques, the system will be able to control and schedule the main domestic loads such as heating, air conditioning and ventilation systems, white goods or lighting among others. The control system is designed following the latest machine-to-machine (M2M) communication trends and standards defined by the oneM2M consortium. Thus, a first approach to the Message Queue Telemetry Transport (MQTT) protocol is presented as a means of developing a smart home appliances control using devices with limited resources.
