I think the idea that there is a security vulnerability in sharing your total power usage is nuts. I was bummed that the metres used by my utility are not compatible. The AVR could periodically wake a radio module and broadcast its readings (say even in a format eerily similar to the idm being watched for by the SDR, allowing for the work discussed in the article to be utilized with an otherwise non-RF or proprietary metre). Tying the IR phototransistor + darlington to an IO on an AVR, configured for pin change interrupt would allow for a very low power overhead pulse counter. Timing and some math reasonably jives with the instantaneous reading on the LCD (reasonably in that the load wasn’t constant, but the computed value falls in the range observed during the sample). A quick mashup of an IR phototransistor driving a darlington to in turn drive another LED allows for easily seeing the pulses. They do have the IR emitter+detector on the front, and with a camera, I’ve determined that the IR emitter blips briefly every couple of seconds or so. Sadly, the Smart metres that PG&E (the utility which “serves” most of Northern California) uses have Silver Springs Networks radios in them, and appear not to support the protocol. I just checked out that project – supporting documentation could use improvement. At least that is what this also shows us. Smart meters are just so dumb to the point it makes Die Hard 4 portrayal of hackers look accurate. Or a terrorist cell finds out the busiest building(s) by average resource-consumption and sends their pawns in for a shoot-n-blast on the likeliest busiest time to ensure maximum carnage. Maybe a criminal group are targeting buildings that report a high average usage as those are people whom can afford to waste and thus must have loads of nice expensive shiney things ( -D). So much data just oozing outta peoples homes without a second thought! So Some idiot gets the wrong side of a gang and said gang goes around a few times scanning for when most people are asleep and at what time of the week so they can perform the least bait-ly drive-by with minimum to no witnesses. Thanks to for the tip! Posted in Tagged, Post navigation. Be sure to check out blog for more details, and for the program used to read the meters. Torrente 3 El Protector Online Sa Prevodom. We’ve seen some in our time, but this one stands out for its simplicity and elegance. In the end, he was able to make some nice graphical layouts of the data with PHP.
Maybe he could just listen in? Using a cheap RTL-SDR, it didn’t take long for to tap into this transmission and stumbled across the power readings for his entire neighborhood using a simple command: ~/gocode/bin/rtlamr -msgtype=idm -format=json -msgtype=scm+ Ironically, the hardest part wasn’t snooping on everyone’s power and water usage patterns in the neighborhood, it was trying to figure out which meter was his. He wondered how the power company monitored his meter, and guessed correctly that it must be transmitting the information wirelessly. Especially the kind that can be lethal if you’re not careful.Īnnoyed by the constant advertisements for the popular Sense Home Energy monitors (which must be installed in the main breaker box by an electrician), set out to find a. Gas and electric analog meters use dials to display energy usage. It is pictured here.1 However, some homes in 1 “Product Specification Sheet - E330 Focus AX + E350 AX-SD Single Phase” found on the web site of the. Wireless Smart Meter that PEPCO is installing in our community is the FOCUS AXR-SD made by Landis+Gyr. Comment: In addition to the vulnerability to hacking and price gouging involved with smart meter technology there is also the very real risk of health problems associated with these meters. Smart meters vulnerable to hacking and tampering.
In addition to the vulnerability to hacking and price gouging involved with smart meter technology there is also.
