Using Home Assistant, adguard home and an $8 smart outlet to avoid brain rot

Neil Chen just posted this genius idea to disable internet filters for social media addicts: https://news.ycombinator.com/item?id=44346450

I've used his idea and make a home assistant automation that temporarily disables adguard home to do the same thing.

NWChen•2h ago
Amazing work & thanks for the shoutout Roman!
FrankPetrilli•2h ago
Seeing this, I had the initial idea of using AdGuard logs to trigger a power-down of your device if you try and visit brainrot content. I think I like it that way more.
stavros•2h ago
Why is this using a plug rather than a Zigbee button? I don't understand the plug bit.
rcarmo•2h ago
The plug has a button, and thus sends out an event when it is manually turned on.
stavros•2h ago
Yes, but so does a button, no?
taude•2h ago
I think this button is powered by the outlet.
ryukoposting•2h ago
Zigbee buttons can last for years on a single coin cell.

I think the smart plug may add a layer of inconvenience, since you have to lean down to the outlet to press it. The inconvenience is a feature in this case, though.

nomel•1h ago
It's literally a button, with some extra stuff attached to it. The only requirement for a button is that if it's accessible to the person trying to press it (no pictures posted of that, feel free to assume). But, there's intentional inaccessibility built into this project, so that may be an intentional goal.

Thats's the great part about home assistant though...anything that can change states, with intent/meaning, is waiting to be tied to an automation.

florbo•13m ago
I'm guessing they already had the plug (I myself have a small stockpile of extra Z-wave/wifi/Zigbee devices for when I inevitably need/want to hook something up), so there wasn't a need to buy something else.
urbandw311er•2h ago
Nice idea. But it needs to be harder for me to reverse. I think I would very quickly develop the reflex of disabling WiFi on my phone so it loads the site via mobile data.

Glad to see GL-iNet get a mention.

Their routers are OpenWrt compatible by design, the factory firmware is based on owrt or you can flash upstream for a "pure" image. I've used them for many years and they're great.

p1necone•2h ago
I don't know if this'll help anyone else or if it's just specific to me but I'll throw it out there anyway.

Drop the idea that short form content like youtube shorts or tik toks or whatever is somehow ignoble and worthy of scorn. Recognize it's just a fun way to kill some time.

Internalized that? Cool.

Now find a comfy place to sit or lie down and binge that shit. For hours. Do it for as long as it brings you joy. Had your fill? Cool.

Keep doing this, whenever you've got some free time and there isn't something else you want to do more binge that short form "brainrot" content. Do not let the thought that you're somehow "wasting" your time enter your mind. You're having fun, and that's all that matters.

If you're anything like me once you've internalized the idea that it's just dumb short videos for fun and you've watched hours of them, you'll just get bored of it. Maybe you'll spend 20 minutes scrolling occasionally but your brain aint gonna rot.

OtomotO•2h ago
That's me circa 2010 when 9gag became really popular.

I used to watch memes and images for hours upon end. Until at some point I just stopped and never did it again.

Over the years people would send some links. I looked at the picture, maybe laughed, and closed the tab.

markerz•2h ago
I kind of agree, but the cost is high for young people. I see similar problems between brain rot and junkie snack foods. Older people grew up without this instant gratification and arent used to it the same way young kids are. I grew up with snacks and crave them regularly, but all my older friends don’t even think about snacks the same way I do. I think the addictive this fades with the development of your brain around 25 years old, as well as increased life experiences, but the addiction to short form entertainment is strong enough to prevent you from getting other forms of life experiences that would eventually make that content boring and feel unfulfilling.

As an example, I used to watch a lot of dance videos. Recently I started taking dance classes and the videos just hit different now. The bar is so much higher for me to feel impressed because I’m digesting the content much more efficiently now and so much content is just repetition with slight variation.

devttyeu•2h ago
There's a recent stat of shorts getting 200B views per day [1]. Assuming 5s per view, and 80 year lifespan, you get 406 lifetimes per day, 144 thousand lifetimes per year. That's genocide numbers and arguably, maybe just maybe, not ok given how shallow this content tends to be.

[1] https://x.com/YouTubeInsider/status/1936193827213394133

charcircuit•2h ago
Entertainment being "deep" doesn't make it any less of a "waste" of time.
femiagbabiaka•2h ago
Nit: Genocide isn't about numbers. And watching reels isn't dying, at least not in any other sense than an existential one.
devttyeu•2h ago
Maybe that's about the wasted human potential that's depressing. Other than that, this analogy only makes sense when framed in terms of some philosophy - i.e. if you are "long-term utilitarian" I don't think it's correct to look at massive consumption of brainrot favorably, even though individual experiences are technically kinda pleasurable.
femiagbabiaka•1h ago
I think the classic midwit response would be to say that in order to determine if this is negative from a longtermism perspective, we'd first have to prove that:

1. this level of preoccupation is a new and historically significant phenomenon

2. the time not spent on scrolling would be spent on something else more productive

Both seem plausible, but they also seem like a couple of those tricky conclusions that seem naturally right but would fall apart with some research. For example, I think it would be better if we all spent time at cafes instead, but it's hard to say that that would result in better societal outcomes.

stavros•2h ago
That's only the case if you think that humans have some higher purpose than distracting themselves, though, which may not be the case for everyone.
Centigonal•2h ago
oh, I wish. I have spent multiple 16 hour days watching just minecraft youtube videos. I'm an adult with responsibilities and many sources of joy and fulfillment outside of youtube. My personal appetite for mindless internet content appears to be infinite.

Spend time examining your own brain to find out why
j_bum•2h ago
I think this is dangerous rhetoric.

I’m glad that you had an experience where you found the corner of your internet to be boring. I do not think this is the common experience.

And simply because you didn’t feel impacted by it, does not mean that it’s not bad. This is obviously hyperbolic, but your comment reads to me like someone saying, “I used narcotics all of the time when I was younger, and I’m fine now. So everybody chill out.” That doesn’t mean narcotics are ok.

Social media does change your brain. It doesn’t take much to find research on this, but here’s an example of a longitudinal study of US adolescents [0].

This type of online content is a form of a non-pharmacological “drug”, so to say, as it can dramatically impact reward system connectivity.

There are helpful nuggets of wisdom here. Also let's acknowledge some people are prone to watch hours of short form content a day, every day, at the expense of everything else in their lives, for a very long consecutive time (of course I know him -- he's me). They really are addicting!
kaashif•28m ago
Actually, I've already tried that and found it boring from the start, not just after a few hours. I found context switching between videos to be exhausting, not worth it given the low amount of content per switch, and I prefer vegging out in front of a movie, documentary, or even 30 min YouTube video to be lower effort. This is independent of any consideration of nobility or scorn.

I think the fact that people are scrolling through this stuff and NOT getting bored or tired is interesting, people are different to me in some way I don't understand.

II2II•26m ago
For some people, that approach may work. If it does work, it's great since it avoids the mental anguish of beating yourself up (which is damaging in it's own right). That said, I can see two scenarios where it won't work: (a) those who have been dealing with the problem for an extended period of time, and (b) those who replace one counter productive habit with another. At the end of the day, we must face the reality that these products are designed to gain and hold people's attention. They are intended to be psychologically difficult to escape from.
userbinator•2h ago
Distracting yourself from distractions by building an overly complex system to help you do that, and writing an article about it, is certainly a very HN-ish thing to do.
gerdesj•1h ago
It is possible that OP has made some parts of the story up or at least sexed it up a bit to jibe with the HN mindset (whatever that is).

I found the article refreshingly short and to the point whilst being jolly amusing and informative. The bloke is German so English is a second language - very good skills.

That's a skilled technical writer, that is.

Bookmarked. More please!

I love Home Assistant.

Many years ago we gave our then-toddler an old digital camera to play with. Some time later, we looked at the pictures he took. We were horrified to find out that he took pictures of the outside of the house at night. As in, our toddler would unlock and open the front door, go outside (at night!), take pictures of the house, go back in, close and lock the door, and go back into his bed. I bought some wireless door sensors and created an automation where if the sensors are triggered between 10pm and 6am, the lights in our room would turn on to wake us up.

I expanded this later and today we have sensors on all doors/windows that kids can use to leave the house (we have 4 young kids). As it happens, these are the same doors/windows that burglars can use to enter the house, so this doubles as an alarm system (that we can activate when we leave the house and will notify us remotely if the sensors are triggered).

The best part is that with Home Assistant you are not locked into an app/ecosystem. Our door/window sensors are of a different brand than our lightbulbs, and we control everything from a single app.

mcgrath_sh•1h ago
What door/window sensors did you use?
polivier•1h ago
I almost went for the Ikea ones, but in the end I went with Aqara. More expensive, but very small/reliable, and the battery holds up very well.
gerdesj•25m ago
I put Zwave window sensors on all windows at work (40 of them). These devices have two AAA cells. One of the gent's window sensors used to "die" far quicker than any of the others and eventually stopped working. I should explain: "gent's" := men's toilet.

The sensors are quite large and simple and the gent's windows tend to be left open more often than the other windows. One of the two gent's sit down toilets is generally preferred to the other for very minor reasons but it is preferred.

So, the battery terminals were getting slightly corroded on that window sensor because it was open more often to the outside environment.

I've rubbed a bit of silicone sealant into the crack between the two parts of the sensor and expect that it will survive better now.

The one thing I’ve found that works for me on my phone is the OneSec app. It hooks into shortcuts (for apps) and a Safari extension (for websites) to prompt you with a small task to do (eg a 20sec breathing exercise) before you access the softblocked content. The time delay + task is enough for me to remind myself that this isn’t what I want to be doing. And in the instances where I actually do consciously want to visit XYZ platform, I can just do the exercise and be granted access.

The only downside is that the Safari extension is granted full access to my web browsing in order to facilitate the website blocking. They say they don’t capture any data and at this point do trust them (you may feel differently). For blocking apps, no private data sharing is required.

johncole•1h ago
Could I use a shortcut on iPhone to do something similar?
varenc•1h ago
I do something similar but with a global keyboard shortcut on my Mac managed with Alfred. When I hit the shortcut it just changes my system's DNS resolver to 1.1.1.1 and reset the macOS DNS cache. And then automatically switches back in 1 minute or 10 minutes depending on the shortcut.

Quite easy, but doesn't help anyone but me. Though I like that it only disables blocking on my device and not my entire network.

gerdesj•1h ago
When I specify smart home stuff, I have several criteria. Things like controls must be mains powered or on UPS or both.

If it is important, then if wifi/ethernet out then it should still work. So my doorbell used to have a link to a mechanical chime (Doorbird), the current Reolink jobbie does not but it is PoE and all my switches have UPS. The Reolink does have a separate chime that plugs into a power socket and a way better camera.

Oh and none of my home things ever get unfettered access to the internet. I have two VLANs for IoT: things is for most devices and sewer is for those that scare me somewhat.

I treat the whole thing the same way I do corporate IT and I do point Nessus at it. I have several Home Assistants that I look after - home and work and several customer ones too.

The OP's choice of smart plug is clearly designed to be mildly inconvenient to get at but also reliable. I'll put money on there being a monitoring function too.

That's a nerd that does things "proper like".

phil21•1h ago
> The Reolink does have a separate chime that plugs into a power socket and a way better camera

I started using PoE to DC power adapters for most of these use-cases. It lets me centralize my UPS to the utility closet, and offer a ton of runtime that way. My router + switching setup now powers my entire house including remote switches (PoE++ powered) and access points. Security cameras (and slowly now - security floodlights) are PoE powered as well. I have probably 12-14 hours of runtime off a large stack of UPS batteries, and could add a few days to that if I wheel my "whole home" UPS I never had the time to hardwire into the house yet into the room.

Items like the fiber NIU and cable modem are powered via PoE splitters into 9/12/24V outputs they require. I still have a few random bridges and other various devices I should convert as well, but I've been lazy lately.

I went with two lower port count "core" switches vs. one so I have redundancy there, so one going out will only take out half my network and I can still operate in a degraded mode - my AP density is such that it works fine, and I can re-patch the in-wall and PoE powered switches for workstations.

The only issue is that it kind of grows with a mind of it's own... I am up to an absurd number of devices on the network now.

gerdesj•37m ago
I live in a UK sticks n bricks two storey roof and a half building. It looks like a bungalow with three bedrooms in the roof on floor one (second floor for the US and other one based countries).

I have two switches in my attic above those bedrooms and most of the rest of IT.

That means I can easily run cable drops along my attic and then under the roof to the outer walls of my house. I've run four Cat 5e to my garage and four to my sitting room.

Basically, I think we are both doing it right.

The biggest criticism of IoT is insecure and unreliable. If you buy any old tat and wire it up to Alexa well that's fine if it hangs together and it mostly does these days. If you squint hard enough, you can forget about Alexa being a bit of a security ... quandry.

There is no such thing as absurd when it comes to automation.

Unfortunately there is no way to block websites at the network level (that I know of) as browsers and mobile phones have started using hardcoded DNS resolvers, so the utility of this is limited.
