The hardware is getting so cheap! But the software... I bought for $20 a bed lamp that comes with led lights, bluetooth receiver, clock and alarm clock, and wireless charging for my iphone. It has a microphone to stream all my conversations god knows where, though its purported purpose is to listen me sing and pulse the lights according to the pitch. It comes with a convenient app to set the clock and the lights. But…

You could try to open it (carefully, you might damage your precious lamp. Also please plug it out beforhand). Often times smart devices like these have debugging ports left on the board you can easily access with some clamps.

Or failing that, desolder the offending speaker to keep the rest of the functionality intact.

It doesn't look like the Z1 does payment either, though. I don't know how they do U2F, but it looks like it comes with a custom reader, which is non-standard. I don't know how Tesla unlock works, so I can't say there.

There is no custom reader. It works with standard NFC readers on Linux and Android.

Ahh interesting, thank you.

I'm so excited to play with this. I just ordered one. I've gone through two Oura rings (I do not reccomend). I'm not sure this will be reliable but it cost me $14.00 not $300 and doesn't charge me monthly to access a mediocre api.

Oura rings do seem to have accurate tracking (unlike most smart watches). The data it collects and the subscription model look awful though. Im eagerly awaiting a ring sleep tracker like it which can be used offline with gadgetbridge or something.

Accurate tracking of what? And which smart watches?

The Apple Watch seems to generally have the most accurate tracking according to most studies, which surprises me.

When I was looking at buying an Oura and browsing user subreddits, it was full of complaints about inaccurate readings and the slow intervals between readings.

Is there a similar ring with NFC? I have no use for the smart health thingies, which really look like a data driven health gimmicks to me. NFC on the other hand I could find hundreds of applications, from payment to access and transport cards.

I have no use for the smart health thingies too, but instead of NFC I want to use it as a controller and display.

Is there a ring with touch or physical buttons. A clicky wheel would even be better. As display I image multiple discreet RGB-leds, but other option could work as well.

At a quick glance this looks cool! I just have a hard time justifying things like this when the apple watch + iphone work so well. But i'm sure at some point the apple experience will get worse and push people to other OS like windows is

Everyone I know that has a smart watch charges it overnight. How do you propose using it to track sleep?

This looks interesting - is there a comparable ring that also has a temperature sensor? It would be interesting to be able to determine if you're sick a day or two ahead like an Oura ring or Apple's new Vitals app for Apple Watch using an open source app. Alternatively, does anyone know if it's possible with the sensors just in this ring?

would also be keen to find one with a temperature sensor, looks like there's nothing remotely near this price point yet?

IMHO companies should not be permitted to "sell" devices that require a subscription to function - that's a rental model - especially when there's only one service provider. Either sell the ring and include lifetime membership for free like Garmin [0], or _lease/rent_ the device on contract and charge a monthly fee. Don't do both The Oura starts at $469 CAD [1] plus $7.99 CAD per month [2]. [0]: https://connect.garmi…

And there's more than a 50/50 chance that if you forget to charge that $469 ring for a few days that it will brick.

Also Oura isn't all that accurate. For anyone who is interested in the wearable space I HIGHLY reccomend The Quantified Scientist[0] on Youtube. He does his best to compare wearable accuracy with real medical devices or other proven devices.

oura ring does function without a subscription, but the data is obviously poorer.

Yeah I specifically referred to the API. Without the subscription their app is pretty whack and outside of that you can only download .csv from a link.

Don't do both An example of something similar is quip¹'s subscription, you buy the toothbrush and subscribing to the refill plan gets you a "lifetime"² warranty 1: getquip.com 2: lifetime of the subscription

What are your thought on risk / reward (more precise: cashflow matching) with regards to physical products with a software component? I think buy (hardware) + fee (software) is the natural way of looking at things. Just as you pay separately for car maintenance. The buy-once, upgrade-years model puts too much risk on the developer. Which in turn results in lousy experiences for customers (dropped support for software…

Buying a car and paying for maintenance is not analogous. You buy the car - it works. Paying for maintenance is just meant to keep it working for longer. You could buy a car, not pay for maintenance and drive it until it breaks. That's very different than buying something that is completely non-functional without the subscription.

Also, aside from some very specific and new instances, car maintenance has not been provided solely by the manufacturer or authorized dealers.
