I have spent several hours looking for a sound sensor that I can integrate into SmartThings. To be honest, there is almost nothing, and absolutely nothing about actual devices, so I am really just wanting confirmation of what I think I know, that it doesn’t exist! I simply want to get a notification or trigger a routine when a high sound level (say over 90 decibels) is detected. Am I right that this doesn’t exist. It seems very odd.
Just to add that I have zero interest in making some kind of homemade device!
So this isn’t all that helpful but the Ring glass break sensor does in fact connect to smartthings via z-wave thus you need the hub. but unfortunately I have yet to find a driver that actually makes it work…
I checked the latest post here and found this post that I had written but not posted! Must have been months ago.
Thanks for pointing that out. It isn’t as expensive as I expected before I checked it out, but it does still seem to be huge overkill for what could simply be a little box that detects sound. I would probably want two, so up to £100 does start to add up. There is also what appears to be quite a big demand for such a device in places such as AirBnBs for checking on loud parties, for example, which would not be appropriate to have a camera for.
If you just want to check the basic noise level, there are lots of apps that will do that on pretty much any smart phone, so you can get a cheap phone, use it on Wi-Fi only, and go from there.
Or as @Andreas_Roedl mentioned, these days, many cameras have that capability.
There are also decibel meters made specifically for Airbnb hosts because of the privacy issues you mentioned, and some of those can work indirectly. But most of those cost about €50 per device plus a €15 per month charge for the monitoring aspect. And then you’d still have to figure out how to hook it into Smartthings.
there are also many sensors that are part of security systems like the ring that was mentioned that can specifically detect a smoke alarm or breaking glass or even a baby crying.
for that matter some of the smart speakers like echo also have some kinds of sound detection.
(Maker types can also build their own for less than $10 per sensor, but you will probably have to bring it in through home assistant. so the integration is a lot more work.
I agree with @Andreas_Roedl that the easiest integration for general sound detection is likely to be with one of the cameras that already integrate with smartthings.
I’ve got a THIRDREALITY vibration sensor that sits on top of my traditional door bell to alert me when it rings based on vibration. I’ve found it’s sensitive enough that it also triggers when there is a loud noise (usually a child). So depending on your use case, it might do what you need. The sensitivity is adjustable and it’s is only around £20 so maybe worth a try
