Hi
Is there a way to connect an arduino to the electric system of a house with PLC ?
Maybe a PLC shield like the ethernet shield or xbee ?
Any idea about that ?
I've seen the sheevaplug product :
More info on it here:
This product is quite open, maybe it would possible to have a look in order to plug a PLC to arduino ?
Any idea is welcome
Thanks
Do you mean powerline communications or PLC as in programmable logic controller.
The links you provided are for an embedded ARM system, they're unable to do networking over power lines. Powerline Networking is probably what you're talking about, like www.homeplug.org. You can probably just use an ethernet shield and an off the shelf ethernet to powerline adapter like these http://www.dlink.com/products/?pid=533
Yes, i'm talking about powerline networking
An ethernet shield + powerline adaptater is a good option. However, it's extremely expensive, and it's 2 separate pieces of electronics
I'd like to know how to create my own plug like the dlink plug, with an arduino
I'd like in fact this arduino to be able to send small amount of data by powerline
This plus doesn't need to provide an external RJ45 plug, because arduino may be too slow to connect a PC to powerline
Any idea to have a low cost plug that can do powerline networking ?
I'd be interested in this also.
My idea is to use the arduino as an electricity meter for an appliance such as a fridge which would report its electricity usage back to another arduino which could then have an ethernet link to a router allowing the uploading of usage data to a database. A third arduino could plug into the mains and display the current usage on an LCD.
Does anyone know if the techology used by the homeplug people is hackable, i.e. any scope for DIY work. I think a simpler protocol than ethernet would do the job just fine. Any suggestions ?
Best regards / Colm
I'd like to do the same thing indeed
Maybe there's an open project somewhere on that ?
How about these two items at Sparkfun?

Someone is using an Arduino for power usage measurement on http://www.mcqn.com/weblog/mazzini_monitors_its_first_appliance#comment-13315 and promises to open-source the hardware diagrams. That's the power measurement sorted out, still left with the powerline communications problem.
Yegads, some is supplying the thing that I'm talking about

We are cutedigi (cutedigi.com), and would like to do a homeplug shield for Arduino. Any suggestions?
Here's a project from ladyada that does more-or-less what you want, but uses an Xbee.
You could do something similar with one of the really cheap transmitters and receivers from China, since you really only need one-way communications.
