I need your input to find a special zWave Sensor. My idea is a little babysitter, which could react on The babie’s cry.
A long time ago, I meant to see a multisensor, which include, what I need.
But I couldn’t find it again.
You could use a Sound Intensity Bricklet from Tinkerforge with the OH Tinkerforge binding, although you need a little bit more hardware than just this cheap bricklet … and it’s not zwave (either wifi or lan cable)
