There is a whole different dynamic to these devices in China. Air quality, water quality, etc. are part of middle class lifestyle in China, and many people do not trust the authorities to keep these parameters within spec. Multiple air filters in an apartment are common, and monitoring the performance of these devices is an obvious interest to their owners. This is a much more compelling home automation story than thermostats or smoke alarms that should be mostly invisible in the home environment.

I've never understood the desire to add smart technology to the smoke alarm. Once properly installed a smoke alarm should be interacted with when (1) there is a fire, (2) the battery is running flat. False alarms pretty much mean you've installed it wrong.

A friend of mine, a great cook, regularly performs what she refers to as The Dance of Smoke Alarm Supplication, wherein she and a broom jointly try to persuade the alarm gods that everything is fine. When she heard that there was a smoke alarm that would pop up a notification on her phone first so she could mute it with zero shrieking, she was very excited.

It may be that her landlord installed it wrong, but landlords (and homeowners) install an impressive number of things wrong, so a business that didn't depend on "amateur does X perfectly" doesn't sound like a bad idea to me.

Ah, the Smoke Alarm Supplication Dance. Great term. My wife and daughter had the same issue. They like to cook and can tomato sauce. Our smoke alarm would go off very easily - lots of false positives. One day my wife is vacuuming the hall and the motor in the vacuum cleaner overheats and starts putting out thick, black smoke right under the smoke alarm. Nothing from the smoke alarm... Needless to say we quickly replaced both the vacuum cleaner and the smoke alarm and made certain to get one with dual sensors...

The Dance of Smoke Alarm Supplication can still apply to smart smoke alarms: https://www.youtube.com/watch?v=BpsMkLaEiOY

I don't know why this was downvoted; I thought it was very relevant.

Yes the landlord installed it wrong.

However in what scenario does a landlord install a £100 smoke alarm when s/he can install a £10 one though? No landlord I've ever had would have done this -- given that over here bills are paid by the tenant a thermostat is usually not provided.

Homeowners can at least move them when they realise they have installed them wrong.

[wpietri]

Some landlords will install a £100 smoke alarm when they realize that they can get real-time notifications that one of their buildings is on fire. Others will do it as a fancy feature to attract higher-paying tenants.

And when the price falls to £30, as happens with these things, a lot more will do it.

Not even on fire, maybe people are smoking inside when they aren't suppose to be. Maybe someone burns their food commonly and that needs investigated before they burn the whole damn place down one time. I can see lots of reasons for that.

Because very few things suck more than coming home from work and your house is burnt down because the smoke alarm wasn't heard by anyone and by the time the fire crews arrive it's too late. Happened to a friend of mine, house was beyond repair even though fire crews arrived 10min after a passing driver noticed the blaze.

A smoke detector is there to alert the occupants of the building so that they get out. If it was an actual alarm system that is connected to a dispatcher, the firefighters would've been notified.

Yeah, as originally designed perhaps, but what if you could add a bit of tech to make sure your pets are safe? Or you're not coming home only to inhale carbon monoxide? I don't think $99 is a ridiculous expense for such peace of mind, even if it's not proven to be full proof just yet.

[JupiterMoon]

My CO alarm sounds pretty loudly. You notice it the moment you open the door again smart it does not need to be.

How would you get your pet out in time if your CO alarm or smoke alarm went off when you were at work?

[webXL]

Perhaps coming home hours earlier from work and/or calling a neighbor would increase their odds of survival.

I find it odd that people are questioning the value of this life and death information while there are plenty of frivolous IOT devices.

[alistairjcbrown]

That's not true - you're meant to test your smoke alarm weekly. Also false alarms can be the smoke detector acting correctly to the presence of smoke, eg. Burnt toast.

In this case the ability to remotely check the alarm status from a self check, or to remotely snooze a false alarm while clearing the smoke can be very handy

[JupiterMoon]

OK so you find it easier to find your phone open the app and then press that button. I find it easier to press the button on the unit. I also find it easier to touch a £10 device with food covered/wet fingers whilst cooking than to get out a £300 smart phone and touch that with food covered or wet fingers.

I agree. They are so cheap. The ones I install are less than ten dollars. Won't name the brand. They are usually on the bottom of the shelf. Hidden away from worrisome consumers that equate price with function. Many contractors buy them by the case.

I usually install two, and run a electrical line to one.

Yes, an app is fine if you burn food, and have the disposable income? I would rather see home owners spend the money on running a line to their smoke, and CO detectors though.
