eHome
I have created this page as a placeholder for publishing information from various sensors and devices around my home. At the moment, you can see real-time electricity usage and my current gas meter reading, along with temperature readings. I’m currently working to build an integrated, open-source gas/electricity/water usage meter reader based on Arduino. I’ll be aiming to make it work with pulse-count meters and those that are ‘opto-reflective’. To follow my progress, check my blog regularly, or visit http://code.google.com/p/arduinometer for code.
How’d you do this?
Electricity usage is currently provided using a CurrentCost electricity meter. For reading my gas meter, I built my own meter using an Arduino. Read this article to build your own.
Electricity and Gas Usage
&g=true&l=Phase%20I&b=true&c=ffcc33 "Electricity consumption over past 24 hours")
&g=true&l=Study&b=true&c=ff0000 "Temperature graph")
&g=true&b=true&c=000000 "Electrical Carbon Footprint")
How is this done?
The graphs are produced by using data that is retrieved from my CurrentCost electricity meter and thermometer every minute, and uploaded to Pachube. Pachube then provide the graphing capabilities. You can get more information on the excellent Pachube service, and how to customise your graphs.
Feed URL
If you’re looking for the Pachube feed url, here it is: http://www.pachube.com/feeds/1347. I have yet to combine my electricity and gas meter usage into one feed. For gas, see http://www.pachube.com/feeds/1851.
You can integrate the feeds in to your own applications in any way you choose – but if you do, please drop me a note and let me know.
