jwagner010 Posted April 16, 2021 Posted April 16, 2021 I am looking for a z-wave vibration sensor, one which is battery powered and 'relatively' small. I know there are multi-sensors out there but really prefer a single purpose vibration sensor device. Similar to this one, which would be perfect for my needs but unfortunately its zigbee: https://www.aqara.com/us/vibration_sensor.html Interested if folks have seen something like this on the market for z-wave? Just FYI before someone asks, I have a range hood that I would like to detect when it is operating. Long story but I cannot get to the wiring (would evolve busting out drywall which I just don't want to deal with). A vibration sensor like this should work well.
larryllix Posted April 16, 2021 Posted April 16, 2021 I would think an air movement detector would be a better option. Trouble is the size of the circuitry/mechanism in that location. Possibly a vane flap with a CAO Tag sensor on it, could work. You would have to change the CR2032 battery every 8-12 months. The dust and grease may be a problem for any mechanism, though.

Depending on how much vibration or rather how little vibration you're trying to detect you may look at "Break Sensors". There are Z-Wave versions of these as they are designed for security for glass breaking. Such as detection of someone breaking a window. Which is why I asked depending on how much or little vibration detection will determine if these would meet the requirements.
KeviNH Posted April 17, 2021 Posted April 17, 2021 (edited) I've got the Fibaro multi-sensor, and it has a seismic motion sensor which is moderately sensitive; mount it on a door frame and it'll detect the door being shut unless you are gentle as all get out -- like most such sensors, it picks up single sharp changes in motion, not subtle repeat vibrations. 20 hours ago, jwagner010 said: I am looking for a z-wave vibration sensor, one which is battery powered and 'relatively' small.

So that's a special case of "vibration" sensing, I'm not sure there's a standalone consumer device available which would accomplish this, I kind of suspect that unless the fan is horribly unbalanced, even that Aqara sensor would not work for your need. By US electrical code, there has to be a way to get at that wiring without busting out drywall. Or maybe you can trace the wires from the hood (or forward from the breaker), find the electrical box where that circuit splits off? Edited April 17, 2021 by KeviNH
jwagner010 Posted April 22, 2021 Author Posted April 22, 2021 Thanks for the suggestions. I have a Aeotec Multi Sensor 6 kicking around, while I hate to use it for this purpose, appears there are not similar z-wave devices per OP, so will look to try the Aeotec this weekend if time permits
