Here is a truth : There ’s no such affair as having too many smoke alarms . There ’s also no such thing as have too many society trying to make heater alarms smart – which is whyRoost , a $ 35 shelling that connects any old bullet alarm system to the web , is so interesting .
A 9 - Volt bombardment that you may install in any smoking or CO warning machine and , using a mobile app , supervise the alarm ’s body process the same path a “ smart ” alarm does . It ’ll send you notifications if the alarm voice , and ping you when you ’re running low on shelling , too . At $ 35 , it ’s far chintzy than most of its purpose - progress competitors .
The musical theme behind Roost is so simple , it ’s almost elegant : Take the concept behind full - fledged merchandise like Birdi Smart Air Monitor ( $ 120 ) , First Alert ’s Smart Smoke Detector ( $ 50 ) , or Nest Protect ( $ 99 ) , and miniaturize it into a garish battery that can be installed on any 9 - Volt dismay that ’s already in your abode . It ’s almost like a merchandise innovation troll : We take your industry - change approximation and put it into a form factor than meg more consumers can give .

Roost first crossed our radiolocation last January when its creatorsshowed us an early prototypeof the gadget at CES . This week , it ’s available to corrupt on Amazon for$35 , or $ 65 for a two - pack .
As a lazy person , I was excited to learn I ’d spend only five second coiffe Roost up , according to the installation guide . After I pried my dust-covered kitchen smoke detector from the ceiling , I see it would take a small longer : All the alarms in my sign run on non - replaceable atomic number 3 - ion batteries , not 9 - V . I fired up Amazon and regulate a $ 10 alarm that extend on 9 - Volts .
Installation is like to other “ smart home ” machine : You swipe through a serial of instructions , enter your wifi password , and then get the app duo with the ironware . But I mention it because the actual coupling process is unusual : You run along your sound ’s Speaker up with the stamp battery ’s border , and it blares 10 - seconds of scratchy dial - up - esque disturbance at the tiny battery . I ’ve reached out to Roost for more info on this physical process , which seems to practice a certain frequency to aerate the bombardment .

After a few attempts , I was connect : A test running game of the alarm sent a loud audio alarm and a crop up - up notification to my sound : Warning ! Your Kitchen alarm is sound !
I popped the barrage out to see what would take place , and sure enough , the battery list itself as “ plow off . ” I was n’t conversant with the other clit on the app ’s main home silver screen , “ Snooze , ” but it ’s pretty useful as well : It break the alarm for a few minutes if you ’re set your dinner ablaze in the kitchen .
you may also set up up your family members , friends , or neighbors as admonisher , which is helpful if you ’re not around much . And through the Roost app , you’re able to set up every alarm clock in your house with a location and keep them in a splashboard for monitoring .

The Mary Leontyne Price is the most crucial characteristic here . You wo n’t get the bells - and - whistles of some overbold alarm , like melodic phrase quality reports or a nightlight , but arguably the important stuff – the connected consternation organization – is there . It ’s hard to imagine a reason to spend $ 15 to $ 85 more for the extras .
I have n’t been essay Roost for very long , but it was enough meter to get a sensation for the level of control it gives you over your alarms ( god uncoerced , I wo n’t ever need to chance out whether it sour during a actual fire ) . compare to competitors who provide full - fledged sassy alarms , there ’s not much missing from Roost ’s core group functionality . It alert you of alarm , tell apart you when you ’re battery is endure low , and permit you pause the alarm when you need to .
It ’s also is designed to last for 5 old age – or 10 if you do n’t beware bribe a $ 15 replenishment battery .

For people who are actually really into the mind of a fully connected home , Roost may seem bare - finger cymbals . It ca n’t offer thing like elaborated readings about your home ’s air quality , or monitor things like temperature or activity . It is its own app , silo’d off from whatever other sassy gadget you might use .
Take Nest , for exercise : The company is work up a whole bionomics of devices that knit a very cohesive web when they ’re used together , from Protect , NestCam , and the Thermostat , to itsdozens of partner devicesthat range from railroad car ship’s company to wash simple machine . For example , if your Protect goes off and you ’re not home , you could look around your apartment using the NestCam and see what ’s happen . What you could do with Nest as a web of devices is powerful – and it ’s only going to get productive as the company further develop its platform .
Roost is really a patch to bring Old alarms up to speed . And really , for Roost itself , everlasting easiness is the whole tar : “ There are no new smoke / CO alarms to buy . No unnecessary restraint panels . No bulky hub to hide . ”

There ’s a trade - off here . Do you need buy new alarms and get a richer , more various weapons platform ? Or do you require to spend a luck less and make your cobweb - coated alarms fresh enough to ping you during an emergency or when they need new batteries ?
If it ’s the latter , go for it . Roost is a genuinely utile thing that will set your perturbing mind at easiness without forcing you to upgrade your entire lot of smoke alarms . Just do n’t gestate it to have the same spear carrier as its more pricey peers .
