[Rest] markets itself as a way to "unlock a new revenue stream"
with the help of a "robust algorithm" for detecting smoking.
Hotels where these sensors are installed rack up complaints and negative reviews, after Rest sensors register false positives - thereby unlocking that revenue stream for the hotels.The awesome thing about black-box algorithms is they can't be challenged when they're wrong. And errors reliably favor the institution that manages (and profits from) them.

So a smoke detector with an "algorithm" attached. Uh huh. How does that algorithm work?
> By analyzing various factors and patterns[...]
Some cutting edge shit here!
And as for accuracy, they don't even pretend to make promises about "99.99% success rates" or anything. This is the most detailed they get:

Okay, but what were the results? https://xkcd.com/1096/
Doesn't the US have false advertisement rules/scam prevention? Around here one person would have to fight this in court to tumble the whole thing down as there is no way Rest can prove it's claim is airtight (pun intended) due to simple statistics and physics (e.g. hair drying leaves burn particulates as well). I doubt it will even come this far as it's obviously a money making scheme over the customers back and acts in bad faith ("The sensor's don't make mistakes" is a claim to innocence where none is valid as almost everyone can smell). It's probably fine as an early detection agent but you'd have to actually check.
Also the charges are disproportionate to the beach of contract, unless they steam clean the room every time they claim the money. Which they obviously don't according to the "dirty room" comments.
https://en.wikipedia.org/wiki/Asset_tokenization
Asset tokenization refers to the process of converting rights to a real-world asset into a digital token on a blockchain or distributed ledger. These tokens represent ownership, rights, or claims on tangible or intangible assets and can be traded or transferred on digital platforms.
https://cointelegraph.com/news/sec-tokenization-exemption-ge...> SEC.. considering changes that would promote tokenization, including an innovation exception that would allow for new trading methods and provide targeted relief to support the development of a tokenized securities ecosystem .. Atkins said the movement of assets onchain is inevitable, stating: “If it can be tokenized, it will be tokenized.”
Well that sort of says everything we'd want to know. They charged the customer $500, like they'll need to tear up the room and bring in a large team to clean everything. But they never bothered with that because they know it's a scam, and the company selling these knows exactly how their customers will use these.
Unsurprisingly, the customers just love this new technology and can't get enough of it:

It contains an air particulates detector and a CO2 detector, plus humidity, temperature, and noise and light sensors. They're probably looking for particulates and CO2 ramp up, hence the "algorithm". It's not clear how accurate this is, but it's not mysterious.
There's a version sold to schools that adds "bullying detector" capability. This adds detection of "keyword calls for help, loud sounds, and gunshots."

(RIP, EPA.)
Plenty alternatives to renting a car in Europe. Hit them where it hertz. Take a punt on smaller companies that are competing with eg total all inclusive insurance. Yup they're a bit more expensive sometimes but can result in an better overall experience (there are lots of scammy local companies too)
- It has a lot of low frequency noise (timescale of hours to days), so you need to do some sort of high pass filter.
- The responses to different VOC compounds don’t even necessarily have the same sign.
So the sensor gives you a “raw” reading that you are supposed to post-process with a specific algorithm to produce a “VOC index” that, under steady state conditions, is a constant irrespective of the actual VOC level. And then you look at it over time and it will go to a higher value to indicate something like “it’s probably stinkier now than it was half an hour ago”.
This, of course, cannot distinguish smoking from perfume or from anything else, nor is it even particularly reliable at indicating anything at all.
Modern PM2.5 meters are actually pretty good, although they struggle in high humidity conditions. But they still can’t distinguish smoking from other sources on fine particles.
Quite some algorithm you got there!
Since then I realized that I won’t always be able to do a chargeback, and I am much more cautious with vendors.
"We can come put tape on the sensors."
"What sensors?"
"There are sensors under the bed."
"Oh, so you already know about this problem but haven't fixed it. Thanks, please don't send anyone."
I then looked under the bed and sure enough there was a motion detector on each side. I removed these from their brackets and let them dangle facing the floor instead of outward. This blinded them and solved the problem. I guess they were malfunctioning or they were able to detect motion above the bed via reflections.
The next day I reported this to the front desk, who were unsympathetic and unhelpful. They told me it was for my own safety. Apparently at other hotels I have just been incredibly lucky not to have fallen down when getting out of bed.
I will not stay at a W hotel again unless I can confirm in advance that they do not have motion detectors under the bed which spuriously turn the lights on at night. Maybe I'll add Hyatt to the no-go list.
Good grief! We are actually going to have a shit list now:
Hertz, Hyatt are the first two entries in this historic development..
"Is it worth the investment?
Absolutely. Hotels equipped with Rest have seen an 84x increase in smoking fine collection. Plus, our smoking detection technology helps prevent damage to rooms and reduce a number of future violations."Apparently there are way more people smoking than we thought there are or the sensor just generates a lot of false positives.
The language they are using all over the site is very interesting though, see here an example:
From how it works:
"Automatically charge
If smoking is detected, your staff gets notified, simplifying the process of charging smoking fees."
With a system with false positives, it makes total sense to use real time notifications to staff to go and check what's going on, that would be legit, but then on top saying that you automatically charge?
It almost feels like they are selling a way to fraud to their customers while covering themselves against any litigation by using the right copy in there to support that it's the responsibility of the Hotel staff to go and check in real time that the violation is actually happening.

I haven't noticed any long-term effects on rooms with frequent vaping though
