You would have to be insane to buy a computer that remains someone else's computer...

I think the key feature is _cooling_ the bed, with warming secondary to that. That arguably sounds like a great nicety to have, notwithstanding all the downsides mentions in the post.

This is a bunch of nonsense, assumption and leaping to conclusions without evidence. "In the second screenshot, we have the public key that’s authorized to access the device. The email address attached to the public key, eng@eightsleep.com, to me suggests the private key is likely accessible to the entire engineering team." He has no evidence for this whatsoever and not really any good reason to assume it either. "In…

Are you denying the existence of an authorised ssh key on each of these beds allowing the holder of the key?

Are you denying there is a config file pointing to a target called remote-connectivity-api.8slp.net?

No there's not enough evidence to prove in a court of law who has access to the private key, or that the config file is enabling a return ssh connection, but it's pretty damning.

The only thing that's not newsworthy about this is that large amounts of IOT shit does this.

The state of the product's security wasn't unexpected. I was, however, shocked by this part: > I was willing to overlook: > The bed costs $2,000 > It won’t function if the internet goes down > Basic features are behind an additional $19/mo subscription > The bed’s only controls are via mobile app Nothing about this bed should depend on off-site servers. Nothing about the product should necessitate a subscription fee.…

Don't blame the market. Blame the engineers who know the risks of such foolishness that lack the courage and conviction to stand up to decision makers.

I have a mortgage so I will follow all lawful orders. I'll blow the whistle if illegal activities are forced upon me, but if there's an ethical issue bothering you, I'd suggest you write to your MP or if you believe they are incompetent or hostile, to run against them in the next election and change the law yourself.

I'm a two-time Eight Sleep customer and the CEO could post my sleep history specifically with my full name and I'd still use it. It's really comfortable. I think most of the detractors were never remotely in the market for such a product. Everything negative said about the product and the company is true, and they should do better, but it's not enough to scare me away thanks to how good the base product is.

I wonder if there'd be a cottage industry for new control boards which de-shittify IOT devices but keep their functionality. Like buy the bed, and then buy a little pre-programmed ESP32 logic board to replace the factory board.

As an EE, there's a healthy amount of this in some industries with very high costs, equipment use beyond manufacturer obsolescence, and in hobby circles with technical enthusiasts. But not generic devices for the general population.

At my day job, we've replaced and re-engineered controllers in industrial laser cutters, CNCs, welders, robots, and similar equipment. There are replacement control boards for hobbyist stuff like pinball machines, motorcycles, retro computers, and retro game consoles.

But as evidenced by the fact that people are buying shitty cloud-only IoT devices, neither the interest nor the capacity to do this is common.

The market deserves some blame here.

My partner has difficulty sleep unless it is the perfect environment (black out curtains, noise cancellation, sound bath, temperature), and is more prone to the effects of a single bad nights sleep. For people like her, $20/mo + $2000 fee is a small price to pay for a solution to a very difficult problem. I would of course, attempt to veto unnecessary IoT devices and subscriptions for usage, but this would be a fight…

She won't get any sleep if the wifi is down.

This all has me quite torn. The "smart" features on it are genuinely useful for me - I have sleep apnea, as well as an eight sleep + the electronic platform. It automatically changes the elevation of my head based on apnea events, and I see a marked reduction in them when using this feature. I have a cpap machine that also makes automatic adjustments but I still get noticeably better sleep quality with the eight slee…

> The "smart" features on it are genuinely useful for me... All of those features could be provided by local compute, either nestled somewhere in the soft and fluffy gross profit margin of a $2,000 product, or with Bluetooth to a "thick" application running on a phone. The reason this product, and so many other "IoT" products, put their compute across the Internet is to facilitate a business model. The industry has t…

Even if it were a nightstand device rather than a phone. The immediate loss of functionality when loss of signal to the mothership is an egregious design flaw. There's no reason the thing can't have a bit of storage so it can then upload the logged data when the signal returns.

Of course, they'll probably claim AI running in the cloud is making the decisions which makes the local first controller not possible.

In addition to everything else, also love how a bed with the express purpose to increase sleep quality requires you to open your phone every time you want to adjust a setting.

I’m still fairly upset that ambient devices never really took off. Nanoleaf at least made a remote like this. It’s a dodecahedron with an accelerometer, so you can program each face with a different setting. The simplest being to program opposing faces for two different light levels. You want to take a nap, turn the controller upside down.

I like this idea, now I want to make one of those. Even a two- or six-sided one would be useful, and I can print different enclosures and reprogram the feather or ESP if I want to add sides.
