Real time reading from AMR Meter

deyrup

Massachusetts is putting some roadblocks in the adoption for smart metering. I was wondering if I could get a wifi enabled radio frequency receiver and decode the signal from my AMR meter; so I could set up something like a smart meter in my house. Is AMR data usually encrypted and will I be able to detect the meter signal with a standard radio receiver? Is there another alternative that would allow me to get real time reads from my gas/electric/water meters?

Frankly, I hope the data are encrypted. Strongly.

That said, even if it is not, you would have to be able to establish communication with the meter; it's not just that it sits there broadcasting, and it's a digital message. A standard radio receiver will only pick up hash, even if you do happen to find the correct channel at that moment.

There are commercial monitors available at least for electric use; not sure about gas or water; which will get you real time usage rate, if not totals.

It probably isn't transmitting a hash, because hashes are one way functions, but I could certainly believe that they encrypt the data.

I didn't mean "hash" in the computer jargon sense of the term; I meant hash in the sense of unreadable radio noise.

I might add that if the data are not encrypted, they are not only in violation of common sense and prudence, but a large and growing number of laws regarding privacy.

Which, of course, isn't to say that they are. Utilities, particularly, are notorious for having perfectly appalling computer security.

If it I can be read by a digital device I can figure out what the encoding is; basically if there is a way to get the data and the data is not encrypted or encrypted stupidly then I have the skills to do the rest. It is the getting the data part that I am not sure how to do.

Which is exactly and precisely why I refuse to permit any form of internet connected or RFD enabled device on my property, except my computers. If you can -- and I do not doubt you -- so can a lot of other people.

No thank you.
