This series is awesome!! I got curious about this when (apparently) unbeknownst to me, my power meter was switched by someone we *thought* was an authorized service tech. It turns out, this guy put a new meter on the house that was registered to some other house. So when the power company showed up to check it out - they thought we had switched it. But that wasn't the case. Now I'm curious how these things work and how we got flagged.

I can think of two things that caused them to come check. First, your meter was no longer reporting back readings. Each meter has an ID number that's associated with your account. Second, a different meter was reporting readings to the surrounding meters that relay it back. This makes it very easy for the utility to determine where it's likely located. Thanks for watching, glad you enjoy it!

You should look at using the built in optical input output interface. On the front right of the meter you’ll see two round holes with an IR diode in them. One is input one is output. We connect to the laptop using them. We can upload firmware and download all data through this optical port. We can even turn on or off your power. They revive and send data like the IR remote for your TV does. Short pluses of IR in 16 bit @9600 baud.

If they are sent to the power company, read some documents or interview some people on where they route that smart data and how its used.

3:32 Hah. We used to use some combination of red mask = alpha or non-form fit; blue = beta or form-fit and green = semi production. Then our CEM said that using anything other than green can be a pain in the arse for fabs and increase cost and leadtime (because, believe it or not, the fabs can use different processes depending on the colour). So now we stick with green for everything because it's cheaper, easier and faster. And, ultimately, it's usually fairly obvious which rev it is without looking at the colour of the board. 4:20 You don't want connectors like that on cert day. They conduct and radiate, even if only capacitively. Also, your final case design matters, even if it's just plastic (but especially if it's metal). It has to be representative of typical usage anyway, so it will normally be in the production box, or something very close to. And without superfluous connectors. Don't need 'em on cert day, don't have time for 'em anyway. 5:30 there is no reason to use series resistors other than either options, as you suggest here, or dV/dt (edge rate) control for the sake of EMC compliance. Sometimes it's for source impedance matching, which is sort of the same thing. But JTAG, nah, that's exactly what you say.

@@HashBoxTV idk about 'allowed'. Basically, if it passes, you're good. If the product you sell is different (there will always be minor changes) and you can justify why it's not materially different from certification, you're good. In practice, probably no-one will care unless you do something obviously stupid or radical, or your equipment is found to be the cause of problems and you get prosecuted for CFR violations. That all said, small changes can have radical effects. One board I did failed EMC because a clock line made a few inches on an outside layer, even though it had plenty of lateral grounding and a nice ground plane underneath. Disabling that and putting an oscillator closer to the load made the problem go away. Sounds obvious when you put it like that, but it isn't so obvious at the time when you design the thing, especially not given all else that is going on. In fact, metal boxes are resonant chambers for RF: it could be that it passed with better margins outside the box than inside it, and they knew this from doing their own precompliance work with a spec-an and either an antenna or an H-field probe. Not saying that happened here, but manufacturers will try to put their product in the best justifiable light possible.

Here regulations enable the certification authority (which is state owned) to recall any meter from any customer to check for accuracy and to validate with the "gold sample" submited in the certification. So, on the instrument side, regulations exist. Not super sure with this smart thing and data being processed in bulk in HES systems ..... (question marks). BUT, the BIG "carrier" that buys and sell power is state owned and have their meter (tipically indirect type class 0.2 or even 0.1) at powers stations. So things must "add up" at some point. Of course this thing can vary from one place to another.

Very nice update. I like how you mix very generic hardware hacking infos and how tos with very specific information on your device. This makes it interesting no matter what your background and state of knowlege is. For the FCC testing, they used most likely some special enclosure. It likely has stuff like cutouts for connectors and indicator leds if the PCB has some. It also has a stand attacked to make sure it stands with a repeatable height and angle. Sometimes, devices also have a special EMC firmware flashed on it, that enables for stuff like continous sending or artifical traffic over interfaces. This is also very common in the automotive area (where I come from). How many smartmeters did you get? In my experience it takes a good amount of backups, since there are more than enough ways to mess up the hardware.

Thanks for the feedback! Interestingly in that FCC report I was scrolling, it shows the FCC emissions testing being done with just the bare board! I hadn't scrolled through that document when I recorded the voiceover. It also shows all the variations of the transmitter being tested, they can support different baud rates and channel allocations so I figure now that's why they took a FCC specific board, they were reflashing it between tests. But surprised they would grant a FCC cert with the device not being in it's enclosure and with additional components on the board that the production version wouldn't have. I have 4 of these newer meters in total, and an eBay seller with about 12 more if I need some. Now that I can power off 12V, i'm fairly confident in my attacking, will see if any protection mechanisms pop up. I also have a few blank processors, so might just enable protection on those and attack before jumping back to the meter. I agree with your experience as well and the same thing I warn others that want to reverse engineer, you're going to break some eggs making an omelette! :)

Are there different levels of certification with the FCC? In the EU you can do severel precomplience tests that are done with different states of your product, some even with early samples and not the final design. However the final measurements (that give you the CE complience) are done with the final product. Another intersting area of electronics is the wireless infrastructure (GSM, WCDMA, GPRS, LTE). I often refere back to the FCC reports, when doing reverse engineering on cellular basestation equipment (my hobby interest field). Sometimes there are whole user mauals and even the proprietrary control software available. The 12V supply is definetly a nice touch. Does the unit use the 60Hz line frequency for something or does it just detect if it is present, like some solar inverters do? Sometimes it also makes sense to go to a fresh start to keep the eggshells out of your omelette, to build on your analogy. ;)

I don't know enough about this stuff.... but wouldn't it be beneficial to have a power supply not only capable of sourcing current... But also sinking current? Completely synchronized in one device. I mentioned source measure units on another one of your videos... with an SMU... You can basically do anything. It's nearly like having a whole test bench in one integrated device Which is hugely beneficial when trying to synchronize a bunch of different processes and measurements quickly and repeatedly with great precision it's all combined in one package and communicating with each other. Just thought with glitching and other attacks.... it would be just as important to sink the power out of the device before starting another cycle. Or possibly even going negative voltage? Rapidly in succession while monitoring everything in unison. Of course this can also be done with separate power supply and electronic load devices. Along with other monitoring equipment and stand-alone pieces of gear. But an all in one integrated device makes everything so fast, programmable, and effortlessly precise. Please ignore if is a dumb idea i honestly don't know enough about glitching to even comment. my specialty is test gear and metrology equipment. So I just thought I would throw that out there.... Since SMU's are used so widely when trying to reverse-engineer or characterize something.

How can you even say that you can make a 240volt system work with 12 volts, explain. Otherwise this is completely nuts and probably illegal. Where did you get the test board from. I'm pretty sure you couldn't buy it..

I run the board on 12V which is what the voltage regulators convert the 240V to so the rest of the circuitry can run. It also needs to see what "looks" like a 240V AC sine wave. The board divides down this voltage to a level that a microchip can use though which is around 3V. So I feed in a 3V sine wave directly to that microchip fooling the smart meter to boot up. You can buy these smart meters on eBay, my other videos I go into more detail on that. Thanks for watching and commenting! Happy to answer questions.

@@RECESSIM So you're telling me that this could not be run on a 12 volt battery. There is a circuit that checks for a 240V AC input and you can fool this by introducing a sine wave. Sorry this makes no sense. whatsoever. Like I said before my son is a development engineer for these things at the very company that makes them. I'm not an engineer but a qualified scientist. I've asked my son to comment but he is too busy working on software development for these very things and will get back to me when he can. He also had a major role in hardware development. That said, I do enjoy your videos, only for the reason though its a bit like watching star trek.

@@RECESSIM Thanks, I will indeed. However can think of no reason why would need to spook voltage 🙂
