> I have made a low cost dB meter that almost any-one can build. This sound meter sends the data by MQTT so it can be easely used in openHAB. The costs are less then € 7.50 It is based on the great work from Ivan Kostoski. The adaptions I have made is the MQTT connection. Find the description to make one yourself at github.

But unless you use something which can filter out the exact frequencies you’re looking for, and match those up to a pattern that you’re looking for, then it’ll be difficult to drown out other noises.

I really like the idea, though - using one device to sense two devices. But it’d be too much faff for me - I’d just stick a power sensor inline on the power cable and call it a day.
