i've worked with highly competent programmes and sysadmins whose houses are entirely connected. they do exist.

    I work in IT, been a software developer for decades.

    I have a full on smart home, all the smart tech you can imagine. All connected and running locally via home assistant.

    Smart tech isn't bad, shitty tech is.

    "Why are you sitting in the dark?"

    "AWS is down 😞"

    Same for me. I don't really like to expose my home and I don't understand how people are so eager to plug in shady WiFi stuff into their network. I've got one "smart" device with WiFi connectivity I've allowed to connect to my network, but I've disallowed going online and I've put it into a different vlan.

    Friend of mine: "let's set up a camera in our bedroom to check on on the dog when we're away."

    The one thing I will never use a smart device for is my door lock. I don't understand how tech literate people really trust that.

    I was considering a smart lock for my (armored) front door, but just because there are some locks manufactured here in Italy that can be set to be controlled by external contacts.
    Which means I could use and ESP or similar with esphome, now they also support wired, ethernet ones.
    That's way more secure than the shitty lock I have now, I've seen videos of people picking that with a decoder device in 30 seconds.

    Locks are not secure anyway and even if it is the most secure lock ever built may I present a window. Most break ins at least when I did home alarms where smash window right beside door and unlock it.

    Again, my door is armored and I live in an apartment high up enough that climbing, while possible, is challenging.
    Together with non-flashy vehicles and the complete absence of anything valuable (besides RAM!), we're not an interesting target. Even if someone broke in they'd have to be an electronics enthusiast to find anything worth stealing.

    Ditto. A smart home that can operate even if the Internet is offline was one of my core goals setting this up. And save for a few exceptions, I accomplished it. It's so jarring now to go on vacation and not have all this automation.

    This is exactly the line of thought I think people aren't seeing as the gap. Y'all are too comfortable expecting the internet to be on 24/7. Or the power, for that matter.

    If Cloudflare shits the bed again, are your lights stuck on or off? Can you not turn up the heat? We're in a period of history where things will bet worse, not better. The last thing I want is "error: can't connect to internet" being why you can't turn the things you can touch in your house on and off. I get it if you've managed to do the work to have it all locally hosted, but just as-is seems like a bet against one's self.

    When the power is off chances are that whatever is integrated is degraded anyway. And for actuators just choose some that fail gracefully and allow manual handling. For the rest use HA as much as possible, favour local integrations with no cloud dependencies… and when there are dependencies than make sure the override is available physically (looking at my vaillant HP). Then stack UPSes or even better home grade batteries (my next endeavour) and have backup connectivity to internet and you’re a peachy as can be.

    as a hardware iot security person, that is possible but too much attack surface to manage

    ZigBee, Z-wave and Thread have virtually 0 attack surface from an IoT perspective, and even then what are they gonna do, do radio hacking to turn off and on my lights? It's not like they can be used in a botnet.
    Locks is a bit more risky as an endeavor, but again, it's probably easier to pick the lock than hack it... Actually with the quality of many smart locks, smashing them is easier still.

    Smart TVs are way more problematic devices for example, as soon as they stop receiving updates, you have a bunch of high-speed internet connected devices with unresolved exploits just sitting there waiting for the right chance.

    Hear hear.

    I feel the meme in the post is created by someone pseudoilliterate in technology. But I can guaranty you they have a smart TV connected to the same WiFi as all their computers and maybe a nas or home server.

    Setting up zwave or ZigBee networks is not an attack vector.
