My thought is to use my XC-3 (or maybe get an XC-2) to connect to an energy monitor receiver – or hack/make a receiver and then push the data somewhere useful via Ethernet. In fact I could combine it with my network monitor, ditch the screen and have it push the all the different types of data out into some nice pretty graphs. Anyway, enough brain dump – onto the hardware!
My proposal is to use a Current Cost Envi (CC128) device. There is a helpful CC128 write up from dale lane. It has several nice features:
- The receiver has a RS232 output
- The receiver outputs XML from the RS232
- The system has support for up to 9 individual appliance monitoring (IAMs)
Some thoughts on software/graphing features:
- Display a comprehensive history (device can output real-time, or 2hr block data)
- Calculate some averages (particularly for time of day, month, season)
- Plot electricity use vs. temperature? – the relationship should be pretty obvious… but I like pretty graphs
- Plot the electricity generation stats and calculate my carbon footprint (ooh err!) – see Amee
- Could even add some X10 stuff in there to… the possibilities are endless

Hi Paul. What's the status of this?
I'm working on some environmental sensors, some LED lighting, a controller, based on XC-2 and a server-side for something very similar.
I'd like to know more about what you are planning. Is this a 'fun' project, or is there a business plan behind it? Are you interested in collaboration.
My sensors are Maxim 1-wire based: Temp, humidity, light, motion, and 'is_power_to_unit'.

Here's an artcle with Xmos reference and an energy monitor app.

Follow the development...
see Silly Science Energy Monitoring Category
.
Development updates will go there primarily. It is progressing... have XML out of the UART now!
Just bookmark silly.
Energy monitoring, great project for energy conscious platforms and projects.
checked out, silly-science, very nice. I'll peruse the site for sure. environmental
ecologic applications are definitely a hot commodity with the current global status.

You seem to be building up a bit of momentum on http://silly-science.co.uk - nice work.
This is great. There are one
This is great. There are one or two projects like this that have been hacked together using Arduinos etc. I like the idea of the device being network-attached. Browser interface is much more friendly. Would be nice to do as much as possible wirelessly too.
