There’s an App for this too

I decided it was time to bring the energy monitoring experience to the small screen so I grabbed one of the open source toolkits for this, namely Titanium from Appcelerator. These guys have done a great job and, though the tools are still in beta, they are a great way to develop and app quickly and deploy it on Android and iPhone. Code is written in HTML, CSS and javascript.
The initial functions provided are displays of data as at now, a daily view and a 3-month history. The part not yet finished is the boiler control where I am still working on the algorithm. It currently just allows the thermostat to be overridden. Watch this space for a more complete version of that. At the moment it’s using ByeByeStandby controller but there have been some service interruptions and so it might be wiser to drive the smart socket from an Arduino - probably the same one that’s handing the sensors.
As I already had all this data online this was a relatively easy thing to do. For the graphics not supported by Titanium I identified a javascript library oddly entitled “flot”. I made versions of my online data viewing pages that deliver JSON data objects. These were very easily accessed from Titanium-provided classes.
Plenty more to do on this. I’d like to get it ready for use by others in a pilot project to see how much energy can be saved. I’ll leave the complex topic of converting awareness into behaviour change for another blog.
