Aren’t all smart TVs dumb if you don’t connect them to the internet? I wouldn’t be surprised if manufacturers start selling TVs that need to be activated online before first use, but I don’t know of any that do that already.

Mine quite happily works as a dumb TV without a connection, and I know many others who do the same. Though I hear stories of TVs being annoying to use without a connection (timing out waiting for a server response that can never come, before falling back to an ad free menu, or just constantly nagging, even while content is playing, about the lack of connectivity).

Yeah I worry about this sort of “annoy the customer into connecting” behavior becoming more common as integrating ads becomes more a part of the business model. Also could connect to open wifi networks in more densely populated areas

The real problem will be integrated cellular connectivity with no option to disable.

Is there a way to avoid YouTube ads on a Smart TV with PiHole? Those ads are becoming more pervasive each month.

I don’t think so. The source of the ads is through YouTube servers as opposed to some separate ad network like on web pages.

Does your TV magically crack the WPA2 password?

Why would it need to? https://news.ycombinator.com/item?id=25275350

>And inevitably someone will say that they'd heard that Smart TVs will connect to unsecured WiFi networks in proximity and start uploading your data.

That's bullshit because that could get into a HIGHLY illegal issue on the manufacturer as they could join into a foreign network tampering with comms. And IDK on the US, but the fines on Europe on that are really high.

My 'smart' TV has no internet connection configured as I use a Chromecast for streaming services and beaming local content.

Likewise (s/Chromecast/Mac Pro/), but mine (LG) has no apparent means to disable Wi-Fi Direct, so it's still potentially vulnerable to local wireless exploits.

Is it? I’m still holding onto my TV from 2014 because it doesn’t have “smart” functionality. Every time I look at new ones I can’t find good dumb ones.

If you don't need any "TV" features such as a tuner or speakers, you might consider using a monitor. I use a 32" 4k monitor as my "TV". In my case, anything with a TV tuner requires an expensive license, so that's another motivating factor, but whenever I use someone else's "smart TV", I'm always relieved that I don't have to deal with glacial UIs and injected ads.

To make matters worse, the SmartTV sold someone in my family just had the SmartTV apps (netflix, etc) taken forcefully off the device because they no longer wished to keep it up to date.

That's why I have an Apple TV attached to a Television I have not connected to an internet ever.

>Apple TV You don't connect your TV but use Apple devices instead. Uhm... okay. You should see the IDS log I'm looking at here. Apple !== no telemetry. All you are doing is putting all your eggs in one basket.

An alternative view is that the parent commenter is being deliberate about which device(s) have access, and decided on Apple over whomever made the TV.

May be we start detaching the Smart into a separate box, or basically buying a large Monitor ? Is there such thing as 55" Monitor? The whole TV industry needs some new thinking and innovation. Right now it is race to the bottom and everyone is trying to get some extra revenues from Data gathering. There are also a huge oversupply from LCD panel maker.

I heard that you can buy a dumb 55" monitor if you call it digital signage. Though these things are expensive because they're made for businesses. Another option is to simply never give your smart TV any kind of network connection.

Sadly, some will look for other open wireless netorks and connect. In the future, I'm sure all will have a 5g connection.

I’m responsible for a bunch of IoT hardware, and every firmware spec I write includes a note on not using the DNS servers provided via DHCP. While sure there are companies explicitly doing this to avoid filtering, at least in my case it’s because a significant proportion of DHCP servers are configured to send DNS to your ISP, and ISP provided DNS is almost universally terrible. They’ll ignore TTLs, rewrite NXDOMAIN r…

Out of curiosity, how do you handle situation where outbound tcp/udp port 53 is blocked? Do you fall back to dhcp supplied dns server?

Jio (India) is super obnoxious in the fact that their own router is locked down hard. Now you cant even change your DNS. I have suggested few people to bypass this limitation by removing the router as dhcp and using pihole for that. That works but don't know for how long. The pathetic thing is their router does not even allow bridging mode. Fuck jio.

You can always put your own router in front of the ISP provided crap, pretty common to have to do that.

Agreed. But that is another expense and essentially you are telling millions of people to buy a second device when the first one is capable of doing just that. Only the ISP has locked shit down. The idea should be to force ISPs to keep stuff open, unless the devices are junk and you definitely need a replacement. That is not the case here. Their router is pretty capable, they just want to control people. Thats bad

How do you deal with NAT64? It's a real thing with some consumer ISPs. I can see myself using it as well, maybe even just to see which devices don't use DNS. Here's another idea: generate a unique IPv6 address per DNS request, route them to the correct destination, filter other IPs. Not really scalable, but usable on small networks/VLANs.

Currently, we don’t. The devices don’t support IPv6, so it’s not a problem we’ve had to deal with so far.

So you'll only start working on the problem when IPv6-aware devices start failing?

Why wait?
