Sure, these exist, and some of them integrate with SmartThings on the new architecture,
AnywayâŠwhat country are you in? The device selection definitely varies on this one.
BTW, these devices are technically called an acoustic sensor, but at least in the US the common marketing term is âlistener.â I suspect so people donât get confused and think it has a smoke or CO sensor built it. (It doesnât.)
- If you use Alexa, that does have this feature in some countries, including both the US and UK, but I havenât looked into the details, and Iâm not sure what you can trigger off of it. This is one of the simplest and easiest methods, but it is cloud based.
I personally find it annoying that the feature will only work when Alexa is set to âawayâ mode, since you might also want it when youâre at home, particularly for smoke detection routines. At our house we ended up putting one echo Dot on a completely separate Amazon account and leaving it always set to Away mode. That works fine. But Iâm still annoyed about it.

OTHER OPTIONS
The following options are mostly US or Canada only: many will probably not work with UK smoke alarms and the zwave ones wonât work with UK hubs. Since the topic title didnât specify country Iâm going to go ahead and list all the ones I know for now.
- for years the best North American integration with SmartThings was the Ecolink Firefighter, available in either zwave or Zigbee.
Both models were still listed in the SmartThings app at the time of this posting.
Zigbee US version:

There are custom edge drivers for at least some models:
- Ring Security Smoke and CO listener. A zwave device sold for use with the Ring security system in the US: not available for the system sold in England. It should connect to a US ST hub, but I donât know what features are available after that.
- Kidde RemoteLync. US only. This is a plug in WiFi device that used to have an Ifttt channel. It was one of the first of these devices to be widely available back in 2015. Technically not discontinued but they are really hard to find now because they have so few integration options.
Listed for completeness and because itâs one of the only standalone options that doesnât require a ST hub,
(Leeo was a similar plug-in device from a start up company, but the company has gone out of business, and the cloud is no longer available. So donât buy this oneâit wonât work.)
-
Various security systems. Since Ring offered theirs, lots of security systems now have proprietary models that only work with their own systems. That includes Abode, ADT, even Arlo has one (requires their security system, not just an Arlo camera). WYZE also. If you have a security system, check to see if one is offered and what if any integration options are possible.
-
Alternative to this whole idea: many people use a relay hardwired into the interconnect line to detect the electrical signals the interconnected hardwired smoke detectors send to each other. Or just a dry contact sensor. This can work in any country. Or if you are in North America you could use Konnected.io
Hereâs a project report from 2013 (!) that lays out this idea. Although all the groovy stuff is obsolete, the basic concept is sound.
Kidde makes a relay specifically for their interconnected alarms for this purpose, but you would be more likely to use a device that already works with SmartThings.
Most of the devices options would require a ST hub because they use zwave or Zigbee, but Shelly does have some WiFi hardwired relay modules with dry contacts that could be used for this purpose and donât need an ST hub. Again this is available for many countries.
Konnected.io would cost more than the other options in this group but has a prebuilt SmartThings cloud to cloud integration that works with the new architecture and excellent customer service. No ST hub required. Hereâs their page on wiring smoke detectors to their system:
Everything in this group requires knowledge of wiring, and none of the integrations other than Konnected.io are plug and play, but itâs a popular option for maker types.
- For the UK specifically, there are a number of devices intended for people who are deaf, which can hear a specific type of UK smoke alarm, and then, either flash of light or shake the bed. The bed shakers in particular would be quite easy to detect with a vibration sensor. So while the solution has a Rube Goldberg feel, it should work.
Here are some typical examples of devices of this type, but there are many available.
I had a hard time finding any devices of this type for the US, but I did find one. Iâm not familiar with the device itself, but I have purchased from this website in the past, and they typically have good prices.
Note that unlike most of the UK models, this one doesnât come as only a bed shaker. It also has a very loud siren built into it. I donât know if thatâs a US safety requirement or what, but you have to be to decide if that was an acceptable feature.
Also, this is considerably more expensive than most of the UK devices. But it would be an option for some people. Just understand that you arenât getting any direct integration with smartthings with this: these devices are creating a physical change in the environment, typically a bed shaker, and then you would use a device that was connected to smartthings to detect that physical change.

So there are some options, depending on exactly what you were looking for and what country you are in.
