Oh wow, this is amazing. There's been a lawsuit in court about someone in Germany who sued their landlord because the landlord has put a Google Nest fire alarm into their flat against their will, ignoring offers by the renter to put in a non-google-non-iot fire alarm at the renter's expense. The landlord won because apparently the court was not convinced that the fire alarm could spy on conversations [1]... What would have happened if Google had secretly put a microphone into their fire alarms as well, not just their home security system?

You could have found it by dismantling the device and the renter would have won their case against the landlord.


I hope you all know that Nest fire alarm aka Nest Protect v2 features microphone for automatic sound (health) checks.


Yeah so the nest protect is, when you look at it objectively, a ceiling mounted general purpose remote sensing package. It’s basically only lacking a wide angle camera and I suspect that’s because they figured it would cross too far into “creepy” for it to be saleable.

It seems to me like a team sat for a while, looked at all the possible ways they could get people to mount a package like this in every room and settled on calling it a smoke alarm.

At the most optimistic they started with a smoke alarm and gradually realised they could build a general purpose platform based on the hardware being deployed in lots of rooms and many types of sensors being dirt cheap now.

Decided they could enable new capabilities (and data goldmines!) in software later.

It’s a pity there’s not an actually customer controlled version of it.


Are there any alternatives to nest protect that would: Sense Carbon Monoxyde AND smoke AND fire off some event to mobile phone via wifi/sms/whatever?


There's the first alert onelink. May have the same issues though, it has a microphone and an alexa integration. Also support homekit, unlike the Nest Protect.

Are there any best practices for using a device like this but not having it communicate with the wider world? I.e. It can communicate with you via a homekit hub, but can't connect outside your LAN

Yes, depending how comfortable you are with soldering.

I use a z-wave smoke detector to supplement the wired smoked detectors in my house: https://www.amazon.com/gp/product/B00KMHXFAI

I then paired it with https://www.home-assistant.io/ to send alerts to my phone, google home, etc.

Haven't had to actually test that the carbon monoxide alarm works yet because testing that is hard/expensive, but for smoke it works just fine.


They don't have to be connected to a network in order to work. The will even happily do self-check without network access - something I realized when I wanted to mute a self-check only to find out that I had done some network changes. Had to use a schtick, like in the old days.

Given that these devices are battery powered and meant to last for years on a single charge you can imagine how often they actually connect to the wireless network. And how much traffic they send.

And again, they work perfectly fine without Internet access. Or network access for that matter. I love them, and as someone with an irrational fear of being in a fire they have helped a lot. They're much more sensitive (without being an issue, due to pre-alarm) than the alternatives.


The sound check takes literally a couple of seconds. How did you even have time to try to silence it?


It tells you in advance and you get a push to your phone if you're on the same network.

"This is a test. The alarm will sounds. The alarm is loud."

(or something like that)


I assumed you didn't get the push notification since your alarms weren't connected to the network properly.

Do you have a 1st gen? I wonder if they're louder. Mine (2nd gen) test pretty quietly. It's not the full-on alarm shriek. It a a medium-volume beeping and only happens for a couple of seconds.


>Had to use a schtick, like in the old days.

What is that? Google's not helping.


usually people use that word when they are suggesting "that's someones schtick" which is like their habit or what they are known for.

Like trump's schtick is getting people riled up


Uhh that’s clearly not what it means here though which is why I asked.


Stick, written weirdly.


No, it's Yiddish parlance for an act, gimmick or commonly employed routine.


That makes no sense in this context. Typo or dictation error (stick -> schtick) makes far more sense.


I read it as "stick" as well. Like how people would use a broom stick to press the 'test' button on classic smoke detectors.

(Admittedly, I have no idea if the Nest version has a similar test)


it wouldn't the case was dismissed, because it's the wrong court. second it was dismissed because just because it's modern and has several technology that can be missused doesn't mean that it will be missused. in germany you need to actually have evidence to really get something like that dismissed. Especially since the landlord actually also offered that she can use her own fire alarm (when she buys it)


As people could - in theory - have with the security system, yet apparently didn't.


And then they probably would have been fined for disabling a fire safety device...


Probably a DMCA violation thanks to our benevolent overlords.


The microphone / motion sensor issues aside I would never sleep in an apartment where someone could remotely silent an alarm.


Keep in mind, you won’t be able to silence Nest Protect if smoke is above levels specified by law. This is an industry rule that all alarms follow. https://nest.com/support/article/How-do-I-silence-Nest-Prote...


I doubt the landlord said the tenant couldn't put up a second fire alarm.


AFAIK, you have to be in close physical proximity to the nest alarm to silence it.


Unless you're the CIA/NSA.


[flagged]


projecting much? :)

I personally agree with the point being afraid of incompetence, not malice.


It’s not as if someone is going to experience a false alarm in their own system, accidentally access your system via a giant security failure and random account mangling, while your system is experiencing a real alarm at the same moment, and then unintentionally silence your alarm. The level of coincidence here is absurd.

The alternative concern that Nest is so incompetent that they somehow issue an automatic silence command (either to all alarms or just yours) seems no more plausible than First Alert being so incompetent that your alarm simply doesn’t work. Especially in combination with the fact that this incompetence must either be undetected permanently (i.e. they always silence your alarm and never notice the horrendous bug) or coincidentally tied to an actual fire in your home, this is probably roughly as likely as a meteorite flattening your house.

The only “viable” concern here is to that an attacker might silence your alarm maliciously, which implies a lot of dedication from an enemy, because they are literally trying to murder you. Presumably this enemy is also an arsonist because otherwise there’s likely no alarm to silence and if there is, it’s likely a false alarm.


your landlord will get the notification about carbon monoxide on their phone. Then they will call you. It might be a false alarm twice. Then it might be real the third time but then they decided to not call you and just silence it.

lot's of thing can happen by incompetence, not even have to go too far on the scenarios.


Why would they silence the alarm? It's just a notification on their phone. Silencing doesn't accomplish anything for them.

The first time my landlord silenced a "false alarm", I'd tell them not to ever do that again. The second time, I'd reset the device and register it under an account they don't control.

But yes, I do see your concern now. I was not initially thinking of the landlord actually controlling the device, merely installing and allowing the tenant to control it. There's a lot less ridiculous coincidence required for a landlord to stupidly silence the alarm.


:D in my country, i never saw anyone with an alarm on their house :D maybe the issue is not to remotely silent the alarm, but that it's needed in the first place :D


Do you also live in a country where homes never catch fire?

“Not needed” implies that there is no fire risk or that the risk is so low that you don’t care.


Legal obligation on landlords in any developed country


Fire codes in many developed regions also require working smoke alarms whether the property is rented or owner-occupied.

Add to that the economic incentives involved when you wish to insure you property against fire and liability, or mortgage it (which almost always imposes a requirement to insure the property).


Replying to myself as I can't edit it any more: Apparently it wasn't a fire alarm from google but "Brunata Metrona Funksystem Star" [1]. It is still wirelessly connected though, not to the internet but to a ground station in the house, outside of the flats of the renters. Then once per year the station is read out by someone who connects a cable to it.

to be fair it was silly that this was handeld at the BVerfG. In now way could that be a "verfassungsproblematische" entscheidung. I mean the person argued, that the lower court argued wrongly about his informational self-determination which is stupid because the person had the chance to buy her own fire alarm (on her own expenses).


The renter did not have the chance to buy the fire alarm, read it again. Instead, the renter offered it but the landlord refused.


Read it again. The landlord refused to buy it, not that the renter could not use it:

> 1. Der Beschwerdeführer wurde von der Vermieterin (im Folgenden: Klägerin) seiner - in einem Mehrfamilienhaus gelegenen - Wohnung auf Duldung des Einbaus von Rauchwarnmeldern in Anspruch genommen. Er lehnte das von der Klägerin ausgesuchte Gerät ab, weil es nicht lediglich dem Brandschutz diene, sondern mittels Ultraschallsensoren und Infrarottechnologie dazu geeignet sei, Bewegungsprofile von Personen zu erstellen, die sich in der Wohnung aufhielten. Sogar die Aufzeichnung von in der Wohnung geführten Gesprächen sei technisch möglich. Der Beschwerdeführer bot der Klägerin an, auf eigene Kosten ein einfacheres, ohne Funktechnik ausgestattetes Modell in seiner Wohnung zu installieren. Dazu war die Klägerin unter Hinweis auf die Vorzüge des von ihr gewählten Gerätetyps nicht bereit. Das Funksystem diene lediglich dem Zweck, eine Fernwartung sämtlicher im Haus befindlicher Geräte über ein im Hausflur installiertes Steuerungsgerät zu ermöglichen.


Yeah, the landlord refused to buy it, but instead wanted to install the wirelessly controlled fire alarm. Surely the renter could buy it for themselves but then there'd be two alarms, one bought by the landlord and one by the renter. The question was about the alarm the landlord installed.


The right to "informational self-determination" (ugly translation from German, sorry) relates as much to things you do not want to do/use/provide as it relates to things you want.


Read it again. The renter offered to install their preferred solution on their own cost, instead of the owners preference. The owner refused, insisting on having the one they picked.
