There are multiple sources where you can purchase a device that will plug into your electrical outlet and monitor your electrical usage and compare it to current costs. The amount of data that the proposed system would handle is the limitation. There is no cost-effective infrastructure setup that would handle all of that streaming data. I do like the idea, though!

Blue tooth is very unsave.
Indeed other devices exist.

This is a growing trend and in fact there are some very cheap devices being created. None that is battle tested yet, I dont believe. The trick is the software side and really it depends on wether you want to interact with the devices...turn them on and off remotely etc...that makes it tricky. There are some wifi/zigbee devices that are coming out and its a VERY hot trend.

hmmm... would this be a great idea if it works on the hype appliances online organizer?

You'd have to engineer/manufacture the data senders that would be a part of this system. That could definitely get pretty costly unless you run across someone already making similar devices. Also, you have to think of the installation side of things. The average homeowner shouldn't really be installing a meter on his gas line, so who is responsible for it? The gas company? Where's their motivation?

Been Done.

oh ill show youve been done wait until you see my fruit stand er wait no wate rlectig gas monitoring idea.

I agree with some of the comments that are made that it is probably better to have WIFI or Wimax and there are indeed already companies out there that are trying to solve the same problem. The field is so new thought, that it is still a wide open field if you have the right solution.

is this a program or a product?

Gas meters in my area have something similar. The gas company just have to wave a wand near some to read the meter (I believe it is RFID or radio) But if this isn't installed certainly don't want to do it your self. If the electrical monitor has to be installed at the breaker box, then a licensed electrician really should do it. A professional should probably also install the water monitor.

So in existing structures, this might be cost prohibitive, but it would make a lot of sense in new construction. Make you device and software and pitch it to builders.

There is a micro controller from Rabbit Microprocessor (A little semiconductor company outside of Sacramento in Northern California) that has a wi-fi dev kit for their processors. This if would be a good development platform. If you want to use this technology I would be glad to help on the project. (I built an autonomous maze solving robot for my senior project for college with one of their processors)

Let me find the link...

The link...

A dev kit for using RF with the rabbit 3000 processor. Includes all hardware, software need to program the controller and work with wireless data transmission. (runs $500 - 600)

The controllers them selves are about $30 depending on volume and of course there is the cost of the RF module, not sure how much that is. So cost of each monitor should be $50-$100
