Looking for a recommendation for an acoustic sensor to detect smoke detector alarms that will work with my smart things hub

Does anyone know where I can purchase a Aeotec sound sensor so I can monitor my smoke detectors?

The Aeotec sound sensor has not yet been released to market. ( this company is known for announcing things that they then take years to bring out of development.)


What country are you in? The device selection available does vary somewhat.

Thanks …. That makes sense since I can’t find it anywhere. Do you know of any other company that offers a sound sensor?

USA… Do you know of any other company that offers a sound sensor?

Yes, there are some, but it depends on exactly what you want.

Do you want:

  1. A sensor that can recognize US regulation smoke alarms or CO2 alarms

  2. a sensor that can recognize glass breaking

  3. A sensor that can just report a general noise level, typically for loud noises, but is not looking for any particular pattern

Looking for a sensor to indicate smoke detector and older hard-wired home alarm activation. Any recommendations… thanks

The one that integrates best with smartthings is on the official “works with SmartThings“ list, the Ecolink Firefighter Audio Sensor. Zwave plus, battery-powered. It specifically listens for the US mandated siren patterns for residential smoke detectors and residential carbon monoxide detectors:

There is a similar plug-in device from Kidde, the RemoteLync. It’s a Wi-Fi device and the only integration is through its IFTTT channel.

(Just be aware that it only works on 2.4 GHz Wi-Fi and your phone has to be on the same Wi-Fi when you set it up. It gets a lot of poor reviews from people who don’t understand how to set up works or who have a phone which keep selecting their 5.0 GHz Wi-Fi automatically. )


Both of these will work with any brand of US smoke detector or carbon monoxide detector as long as it uses the standard alert pattern.

As a curiosity I am interested in finding a UK equivalent to the acoustic sensors like the Ecolink. That is one that can recognise UK rather than US audio patterns.

If any one has any suggestions please add them to this thread. As a starter I found the following. It appears to be ‘trainable’ to recognise acoustic patterns so might work with various systems.


which works with the matching gateway

Some technical info for it is here

The legal definitions of the acoustic pattern of a smoke detector vary significantly from country to country.

In the US it is a simple beep pattern at a specific high decibel repeated over and over at a regular interval. It’s quite easy for a sensor to distinguish from other sounds.

In the U.K., it is much more complex. It starts out soft and gradually gets louder. The interval also changes. This is supposed to be better for waking children. But it is also very hard to design an inexpensive acoustic sensor that can detect it without throwing a lot of false alarms.

Reportedly this is why the Alexa Guard feature has not been released for the U.K.

So my guess is that there just aren’t any for the U.K. residential market.

Instead of an acoustic sensor, why not have a smoke detector with siren that integrates with Smartthings, such as this [RELEASE] Xiaomi Honeywell Zigbee Smoke Detector (Beta)

I’ve got one and supplements my existing hardwired detectors

An acoustic sensor would not be able to easily distinguish the noise as coming from your smoke detectors.
