  • Twenty four US states are now considering legislation to allow small, plug-in solar power systems that connect directly into a wall socket.

  • Like I said, I’m weak on the science. I’m more of a computer person.

    Most of what I know is based on either a Practical Engineering or Matt Ferrell video, but I’m interested in the topic, if a little too busy to dig deeply enough to get past the marketing. If you have a good info source on the matter, I’d love to check it out.

    With that said, the first paragraph is not really applicable to my concern, which is that a grid connected panel + battery could be hacked. En masse, they could dump power onto the grid and fry transformers or take out substations. (Which smarter people than I have identified as a concern, re: EV chargers.)

  • That’s the dream. After years I finally got serious about learning/implementing VLANs and have begun to isolate everything out/properly firewall them. Most of the smart home stuff is already Z-Wave/Zigbee, but the few devices that aren’t are mostly already migrated onto a dedicated IOT network, as is the hubs, where only devices that have business talking to each other can even see one another.

    I have yet to play with tailscale, but it’s on the list.

  • Hm. Imprecise on my part.The panels aren’t the concern. It’s stored energy in the battery that can be dumped onto the grid, along with the stored energy of other compromised systems.

    The article I linked outlines a scenario like what I’m describing being possible with EV’s that have had their chargers hacked.

  • I love the idea. Scares the shit out of me.

    I’m not as concerned with these things starting house fires, but I want to explain that away first. I’m a little weak on the science, but my understanding of how these work is that they attune to the grid frequency and voltage to deliver power at a slightly lower frequency than what is provided by your wall plug. This allows them to augment your home power use without refeeding power into the local grid. IIRC, if there’s no wall power, they only offer power through outlets on the devices themselves, vs through the wall plugs.And, I think that the above safety feature will prevent over-amperage situations for in-house wiring loops, since the device cannot exceed the power delivery of the circuit it’s plugged into, when operating normally.

    These things scare the shit out of me because the U.S. power grid is badly under-engineered. Before actual electrical engineers hunt me down and kill me, think of building a bridge. You can do that by just pouring a billion tons of concrete into a ravine. But building something that is material and budget conscious while being safe enough to avoid lawsuits is not what I’m getting at. (Think of the phrase “Anyone can build a bridge, but not anyone can build a bridge that barely stands.”)It’s a feature, not a bug. Otherwise, power lines would be I-Beams and we’d have some sort of insane switching technology to isolate and shut off every single segment of the grid.But we don’t! Homes are never disconnected from the grid unless specialized hardware is installed at the meter to disconnect them. (Which happens for distributed/co-generation scenarios.)

    The existence of always connected power generation or storage sources as a potential threat vector is well known. In 2023, it caused a minor kerfluffle as several brands of EV chargers were shown to be easily hackable and as few as 300 of them could be used to take down a regional power grid. Not everyone can afford an EV, and usually those users are a tad more tech savvy. They generally are not buying third party chargers, anyway.But the rate of adoption for these devices could be significantly higher. The law of averages being what it is, I think these pose a much higher threat to the grid from hacking. Everyone loves apps. No one thinks about security. They could easily exploited, rooted, and have their safety features disabled. Who needs 300 EV’s when you have 300,000 balcony chargers?

    Funnily enough, these would be in high demand if the U.S. grid got fried. It would take years to undo the damage.

  • I like smart home stuff. I hate my privacy being invaded. It’s a very thin line to walk.

    A company recently released a product that promises to be Matter compatible. By the time the product arrived, they edited their product description to say it worked with Matter if you bought their always online hub, created an account, let their hub talk to the internet, and then installed their internet-connected plugin to Home Assistant. (So it’s not that HA talks to these devices, or that it talks to their hub. It logs into the company’s servers to get the current state of the device.)

    I wrote a review outlining this. An AI bot sent me a message offering me additional products from this company. (Ha!) And included the line “We strictly adhere to data protection regulations” … in the U.S?

    Laughably misleading.

  • I had the creepiest conversation with a cop a few months ago.My neighborhood is seemingly getting rougher by the day. I do have a video doorbell, but it’s not one of the major U.S. brands.

    Anyway, it was trash day. Garbage had been collected. I had noticed several police cars around, but didn’t see any police. I went to collect my bins, and one of them popped out of nowhere to chat at me.

    He was light on details, but needed to track the comings and goings of a parking lot across the street from my house. Didn’t need super clear images, just said he needed timestamps for a timeline. Said my camera angle was ‘perfect’.And it is! I get so many alerts that I disabled it unless motion is detected within the area of my yard. (Which was not helpful to them.)

    But he was explaining this to me, and said that he needed me to send them the video (before I told him that it was unlikely I had video, and then confirmed that I did not with him). A moment later, he did a quick scan of my various neighbors houses, and said (to himself) “Okay, that’s a Ring, that won’t be a problem.”

    A problem?!? Just casually warrentlessly seizing footage from people’s homes is not a problem?

    For those curious, the system I currently have is by Eufy and I cannot recommend the brand. Anker as a brand has been great (Eufy’s parent company), but I find the Eufy app to be riddled with spam, the offered features to be mediocre, and generally, customer service to be poor. They even had an amazon review removed once. (I called their app a piece of crap, and they hit it with a community standards warning to get it removed.)

  • I like it. I would not go back.

    But I have a nice home office, don’t live alone, and found office culture and colleagues to be disruptive.I have ADHD. My job tends to be wide but not necessarily deep. A “quick question” can cause me to lose my train of thought, cause me to get disordered while trying to figure what the hell I was doing, get shut down by the frustration, and lose hours in ‘wait mode’ for the next interruption because it took me so long to enter a flow state that I’m fearful I’ll get interrupted again.

    Being able to shut my office door, silence notifications, and focus with music playing in the background has been incredible for me.

  • I have (had?) an arms length friend that is prone to making bad choices.He aspires to be a decent guy, but struggles with making the right choices. He made some pretty bad choices last year.

    Cheated on his wife with a coworker that was, er, not someone I’d trust. Got caught. Coworker then got pregnant. A few months later he called me to ask if he could crash in our guest bedroom for ‘no more than three days’ while he cut things off with the coworker and worked on reconciling with the wife. While he was still that coworker’s supervisor and baby daddy, unbeknownst to his supervisors.Seeing nothing but red flags there, I offered to pay for a hotel room for him for a week, and he never took me up on the offer. My wife’s eyebrows were almost at the ceiling when we got off the phone. She very much appreciated not inviting that mess into our lives. I haven’t heard from him since.

  • The house numbers on my block always skip one.

    For example, if my block number was the 10th block, on the odd side of the street, the house numbers are 101, 105, 109, 1013, 1017. And on the even side, they’re 100, 104, 108, 1012, 1016. (Sub dividing houses is common here, maybe they wanted extra addressing space?)

    Sometime last year, I caught an Amazon driver stalking through the back yard, as he tried to find one of those in-between addresses. Sadly he didn’t just leave the boxes at the map pin.
