The attacks could be pulled off by stealing meters - which can be situated outside of a home - and reprogramming them. Or an attacker could sit near a home or business and wirelessly hack the meter from a laptop, according to Joshua Wright , a senior security analyst with InGuardians Inc. The firm was hired by three utilities to study their smart meters' resistance to attack. These utilities, which he would not name, have already installed a few smart meters and plan to roll the technology out to hundreds of thousands of power customers, Wright said told the Associated Press.
There is no evidence that the security flaws have been exploited, although Wright said a utility could have been hacked without knowing it. InGuardians said it is working with the utilities to fix the problems. California's largest utility, Pacific Gas and Electric Co.
It came back on, and I noticed a smell of smoke around my central heater. The heater would not come on, even when I raised the house temp. Finally it came on, ran for just two minutes and went off again. This happened two or three times, but after about 15 minutes it began to work normally again.
Thank you Ed N. Comment by Ed Noonen — March 16, pm. No, extremely unlikely. Comment by Nate Lawson — March 17, pm. Comment by Dave — May 13, am. Dave, thank you for this explanation, sounds right to me. Comment by Ed Noonen — May 13, am. If these meters can be used to shut off supply can someone hack into the star rf transmitter I dont know if its two way and change the reading on the meter itself. I have other friends in NY who are experiencing the same close encounters of the third kind with their water meters since the amr install.
Thanks Joe. Comment by Joe S — April 11, pm. However, I think the more likely culprit is ordinary billing mistakes e. They do decrease mistakes in reading digits transposed in your usage. Most people complaining about higher rates from their meters are loons. Comment by Nate Lawson — April 12, pm. I traced it down to one circuit on our home. When I turn off that circuit the Kwhr drops by. I turned off all other circuits and unplugged all the devices from all the outlets on the circuit in question.
It still registered. Just to be sure, I disconnected all the outlets on that circuit three bedrooms. It still registers a power consumption of about. This defies the laws of electricity. There is no load on the circuit, still the meter is registering a power consumption. Do smart meters read or fingerprint individual circuits in a home?
In my case reading a power consumption, a load, when there is none? Comment by Chris Bea — April 13, am. Are you sure outlets are the only things on that circuit? What about water heaters or something else not visible at an outlet?
So you should be able to track it yourself and compare to the numbers the power company is reporting. Basically, smart meters work the same as an ammeter. Comment by Nate Lawson — April 16, pm. Thanks Nate. It continuously displays a cumulative or to-date Kwhr usage and below that it alternates between displaying the volts and the current Kwhr reading. Comment by Chris Bea — April 17, am.
It sounds like there is something drawing power on that circuit. Comment by Nate Lawson — April 20, am. My main problem with these smart meters is privacy. These units allow anyone with access to know what your doing most of the time. Figure you have a smart electric meter and water which with many tools from the likes of google will allow you to monitor excactly what your useing and when.
Its able to determing wether you have a light bulb on and in the future what outlet its plugged into. So they whoever they end up being will be able to know about when you wake up, go to bed, watch tv, use computer, cook, open a fridge, turn on the light to the bathroom and how regular you do these things.
With the smart meter on your water they can know when you flush estimateing about how long it takes to fill a tank of water to the federal law of something like 2. Now I know most will poo poo all this and say who cares.
I DO, I care because its my personal space. At some point we have to say enough is enough. There would be charges levied against the gas stations for price gulging. We are buying units of energy. I cant see how everyone got duped into this scam. Everyone remembers Enron but not the lesson. It also gives finer granularity of electrical usage. As mentioned in other HaD articles some do have issues about their bills not being an accurate reflection of usage. As the saying goes…. A month of monitoring and he was able to prove it.
Not wrong by much but wrong. Monitoring the RF would never had revealed the issue. Which is accurate? The cheap clip-on or the utility meter that is supposed to have traceable accuracy? The only way to trust and verify is to do primary injection testing, not replacing one fallible meter with another likely cheaper one with no legal requirement to calibrate.
What some are doing is placing a traceable analog meter in parallel with the digital. Installed by a licensed electrician no less. Any chance of this working on the type of meters used in Canada? It says that model is compatible with multiple standards, it would depend on how it is set up I imagine.
Easiest way to check, run the program and see what happens. Not mentioned in the article that I found after reading it quickly was the protocols in use by the meters. My understanding is that these are using IEEE Is there any hope to decode these transmissions? I look forward to the scenes from the next chapter!
I guess this is OK, if you simply want to know ahead of time, what your electric bill is likely to be, but as the data is only sent on a sporadic basis e. Electricity companies are not keen on customers knowing how much power they are consuming, as their bottom line depends on people consuming more electricity not less. So they are not going to make it easy to get this information, even though its beneficial to the consumer and the planet.
The command front and center in the article is misleading. I would guess that msgtype will have the value provided in the first flag use. I should also note that K-roy and I have really bad timing. To solve essentially the same problem it looks like he put a lot of effort into solving. With a Rainforest EMU2 handling all the RF reception and protocol handling, you can have continuous, near-instantaneous knowledge of power consumption, bill amount, etc.
I used that for about a year, connected to a RPi, it uploaded the data ever 10 seconds and made a few pretty graphs. My recordings matched nearly exactly with visual reading of the power meter and what I was billed for monthly but who knows how accurate the meter reading is. Which meter do you have? What meter type do you have? What frequency and protocol is used?
I want real-time reconciliation of my solar production vs. Ah, I see. The Rainforest EMU2 is blessed by the power company.
