xkcd #3109: Dehumidifier

Title text:

It's important for devices to have internet connectivity so the manufacturer can patch remote exploits.

Transcript:

[A store salesman, Hairy, is showing Cueball a dehumidifier, with a "SALE" label on it. Several other unidentified devices, possibly other dehumidifier models, are shown in the store as well.]

Salesman: This dehumidifier model features built-in WiFi for remote updates.
Cueball: Great! That will be really useful if they discover a new kind of water.

    What about !diyelectronics@programming.dev?

    Or if you are using Home Assistant you could post in !homeassistant@lemmy.world

    There is a Lemmy community search function here if you want to check other options: https://lemmyverse.net/communities

    That's odd. How far did you get? Any error?

    Federation from your instance Lemmy.world to the instance the community is on (programming.dev) is healthy, so that doesn't seem to be the issue.

    My guess would be that you've tried to upload an image that is over the size limit - I think this is imposed by your own instance (Lemmy.world), and I'm not sure what the size limit is but I think 5MB per image is pretty common. If you drop the image size or upload elsewhere then link it, does that work?

    I just installed motorized dampers in my crawl space using Shelly smart relays! Now I have an automatic schedule so I'm not cooling rooms that aren't in use (like the bedrooms during the day and the lower level of the house at night). Already seen significant power savings!

  • It would be a lot more difficult to hide a backdoor on a bare ESP device, than a proprietary Tuya one, just putting that out there. Regardless, I still block internet access from my ESPHome devices, because I don't want to feel like I need to constantly be on top of updates, that can cause things to break at times. I do them every couple months when I have the time to sit down and make sure everything's still working, or roll it back where it's not.

    I’ve looked into many WiFi dehumidifier’s and the one thing I wanted from it was to notify my phone if it’s full. None of them do that. All they do is let you change speed and stuff. Nothing that is important to me. I just want to know if I need to go to the basement and empty it or not.

    Right? Like half of what I want from these things is when is the battery low? When is the outbox full? When is the feeder empty? And metrics to verify the device is generally operating safely.

    Controlling the device? We've known how to do that for 50+ years. Help me maintain the device.

    I feel you, trying to find a smart gadget that is actually smart in 2025 and not just a data collector is nearly impossible. Learning to DIY a lot of these projects. Throw one of these or similar in there with a little control board set to email you if 0 changes to 1 or w/e

    I need to look into this and see if I can have it send me a text or something when it’s full. Another diy project to add to the list.

    This is the around the long way method, but it'll start you on a crippling hobby to instrument your entire life.

    Raspberry Pi home assistant zigbee USB zigbee water sensor.

    you could stop here at notifications.

    or

    Descend into madness, put a small ac submersible pump into your dehumidifier tray with a smart outlet. When the sensor trips full, have it run the submersible pump for x minutes.

    Pet Wirecutter, Midea and Frigidaire both have smart options that have full bucket notifications. It's baffling that they don't advertise that feature in their product listings, though.

    Welp if they don’t advertise it I’m not going to buy it. I bought the “dumb” Frigidaire because the smart features they list are just turn on and off and fan speed. Why wouldn’t they list full bucket ffs. Oh well time to diy solution it.

    Do they have a model with AI?

    You joke but my dehumidifier has an automatic comfort mode of some sort.

    I guarantee that next run will have that button with screen print AI something something above it instead.

    I got new appliances a couple weeks ago and they're all "smart". Turns out a smart microwave just sends you a phone notification when it's done. By default.

    As someone with multiple people living in the house, I can confidently say this is the dumbest "smart" feature ever. Promptly disabled.

    Most people tend to stay in the same room (or a neighbouring room) when they're microwaving something. They could probably save on the cost of having a full-blown computer with wifi inside the microwave by just having the noisy thing from an alarm clock. But, ah, the fuck do I know?

    Some 90's microwaves actually used some chips to measure humidity and using a little reference table adjust how long certain foods need to cook for, for instance, popcorn can be popped perfectly without burning and almost without leftover kernels if you can measure how much water is being released. The same goes for cooking frozen meats, vegetables, and so on.

    But what we get in modern ones instead are horrendous touchscreens, simple timers that never quite match the food they promise to work on, and Wi-Fi.

    The only smart thing I'd want an oven to do would be to turn itself off. That's it, really. Did I leave the oven on after I left the house? Easy fix. Otherwise everything else is pretty much useless.

    I don't know, I wouldn't mind also being able to tell it to start to preheat while I'm on my way home. Would save a chunk of time if I could literally walk in the door and throw the food in the oven without the extra wait for it to preheat which is usually long enough to be annoying but not long enough to do anything else.

    My stove won't preheat, I guess because it's a safety issue. Apparently you can set a remote start capability ahead of time that gets reset if you open the over door. But I've never tried it, since that seems like a lot.

    Remote preheating sounds like a terrible idea. What if you mistakenly left something in there?

    Any appliance with IoT is a value-subtract.

    They do it so in the future they can monetize you in perpetuity in some way

    I can see value in HVAC IoT. Away from home and there's a cold spell? Turn up the heating so your pipes don't freeze, but also run it higher when electricity is cheaper (if you have variable pricing).

    I don't think I'd want my microwave, washing machine, or toilet to have IoT features though.

    My toilet sings when I lift the lid or sit down. I kind of wish I could upload a new song after all these years

    I want my washing machine to notify my phone when a cycle completes... But maybe not quite that much

    Mine chimes a quaint little song. It's enough because it can be heard pretty much anywhere in the house unless I'm in the basement. If I'm not home, the notification wouldn't be particularly useful - I might as well just check when I get home.

    I mean the idea isn't the absolute worst. I just don't think it's a huge QoL improvement either.

    Any decent heating system will have a thermostat which will activate the heating when it's getting cold. Also no need for internet to be able to setup the time when electricity is cheaper. It's not like it's something you need to do regularly. Setting this all up directly on the heating system works well enough.

    How long are people microwaving things to the point where that is useful??!
