First Alert today announced that its Onelink Safe & Sound, an all-in-one smoke detector, carbon monoxide detector, and speaker system, now supports AirPlay 2 for multi-room audio playback.

AirPlay‌ 2 enables multi-room audio playback with other ‌AirPlay‌ 2 devices, such as the HomePod, Apple TV, and select speakers from Sonos, Bose, Bowers & Wilkins, and others. ‌Users can select where the music is playing in Control Center on an iOS device or ask Siri to play music in a specific room or the whole home.

Introduced at CES 2018, the Onelink Safe & Sound distinguishes itself from a traditional smoke detector with a built-in speaker and noice-canceling microphones, plus support for Amazon Alexa.

With existing HomeKit support, homeowners can add the Onelink Safe & Sound to the Home app and receive push notifications if smoke or carbon monoxide are detected. HomeKit also allows the detector and music playback to be controlled with Siri using an iPhone, iPad, Apple Watch, Apple TV, or HomePod.

Regularly priced at $249.99, the Onelink Safe & Sound is currently on sale for $178.25 on Amazon in the United States.

This... sounds like a clever merging of devices.

I'm not going to pay $250 for a fancy smoke detector, but adding a smart speaker to it makes it a lot more appealing.

I wonder what else could be merged into this one device... a camera? An LED? VR Beacons (or Lighthouses or whatever the heck they're called.)
 
For that price, you'd be better off getting a dumb smoke/CO detector and a HomePod (on sale).
That is waaaay too much for a device that should be replaced every 10 years. (Some recommend 7 years.)
Really...any AirPlay 2 speaker will sound better than this.
No. I haven't heard one of these. It's just common sense.

I bought one of these on the Costco black friday sale last year ($99 and it came with another normal smoke detector). I am really impressed with the sound quality considering it is coming from a smoke detector. I also like the light being available in homekit and I used it as a nightlight in my Scenes.

Is it possible to disable the Alexa microphones in these things (for use in privacy required areas), and still have them work with HomeKit and AirPlay?

Kinda makes sense, until one of the components breaks. None of these are particularly expensive, but are a small fortune combined. Personally I won't use this type of functional consolidation. If you like it... great!
 
Garbage. I know first hand this product is crap. I mean first of all for the price I can buy 10 smoke alarms plus a Bluetooth speaker or Alexa device. Second the app for this product is horrible no support whatsoever. Third the song quality is horrendous.And the company itself is a joke
 
I don't need more cheap little speakers. What I do need is another way to interact with Siri. This thing has microphones but only talks to Alexa? Fail.

If I could talk to my Apple TV without having to pick up the remote I guess I would be good.

You can not tell Siri via Apple Watch to play music to an AirPlay speaker.
 
I like how in the picture they have it installed on the ceiling. If the carbon monoxide alarm goes off, you’re dead. I don’t understand why companies insist on putting smoke alarms and carbon monoxide alarms in one unit.

Because actual science says it's not a problem. First, look at the periodic table. CO is lighter than O2 and N2, since C is lighter than both N and O. So if anything, CO accumulates near the ceiling, not the floor.

The actual density of CO is 1.14 kg/m3 whereas air is 1.18 kg/m3 at room temperature.

In actuality, the density of CO is close enough to air that natural air currents cause a fairly even distribution anyway. In fact, O2 has a density of 1.33 kg/m3 and N2 has a density of 1.17 kg/m3, yet they don't stratify and cause us to asphyxiate when we stand on a ladder. Therefore, there is no need for a specific height to mount CO detectors.

You are probably right, but it still seems like an unnecessary risk indoors where there may not be much air movement. For instance, my house doesn’t have forced air.

btw thanks for the info. It was good for me to research it again. I’ve heard all my life that it is heavier than air.

That price tag...
I have ZigBee SmokeDetectors that double as siren for the alarm system.
CO sensor indoor is rather pointless. The only exception is if you happen to have an open fireplace or gasfired water heater.
Literally every other smart speaker will sound better than this.
...and will even be a lot cheaper and more redundant when bought separately.

Wrong. CO detectors are required by law in nearly all US states in homes that have fuel-fired appliances. 2/3 of US homes are heated by some form of gas or oil. The majority of these homes are heated by forced-air systems, if there is a crack in the heat exchanger, then CO poisoning will likely result.

Carbon Monoxide Kills More Americans Than Mass Shootings, Terrorism Combined

The point isn't to scare people about accidental carbon monoxide poisoning, which kills, on average, 374 people per year. Given our population of 319 million, that's a minor threat. Instead, this is to show that the chaotic stuff that makes the nightly newscasts is far less likely to kill you...

This is such a common myth it pisses me off. Thank you for your simple and technical explanation of why.
