HomeAutomationHub now in use

Sunday, September 18th, 2011

This week saw the introduction of the Home Automation Hub which I put together last weekend. The primary function so far is to act as a bridge for the Current Cost monitor system and Pachube. This has replaced my old solution which collected data into a local MySQL database and then sent averaged results to Pachube. This was somewhat inefficient and not easy to extend. the HAH means that I have now been able to integrate the Individual Applicance Modules that work with the CC unit – so Pachube presently has five streams of data.

One of these streams will allow me, for the first time, to reliably monitor the power consumption of the Christmas Lights. I previously tried to do this with a Maplin plug-in monitor which melted a few years ago making an odd smell and posed something of an unexpected danger!

Construction was fairly straightforward, however this is not a project to the novice constructor and a reasonable level of skill in working without highly detailed instructions was necessary. Nothing particularly difficult, though, and it worked first time. It took longer to get to grips with configuration of the data streams as this requires some careful reading and interpretation of the notes. I have yet to work out the best way to try and integrate things with the X10 house control system – and if it won’t work directly the xAP system which is deeply embedded looks promising.

The HAH will allow for additional functions in due course, perhaps one day to include a garden watering system – pending getting A Round Tuit.
