THIRDREALITYZigbee Vibration Sensor, 110dB Alarm, Adjustable Sensitivity, Works with Echo, SmartThings, Home Assistant

These sensors are well-made, easy to connect, and have multiple applications. I have several installed around my house, and every day I find a new use case - (1) attach it under the sink and have lights turn on when doing dishes, (2) attach it to the cabinet doors and have lights turn on when cabinet doors are opened, (3) Get notified when washing machine, dryer, dishwasher cycle ends, (4) Get notified when mail box opened/closed, (5) I have a delivery box in my porch, so have one sensor there to get notified when I get a delivery, (6) Turn on the lights when fridge door is opened, (7) Turn on light and turn on my music/podcase when I start the treadmill ... Just unlimited use cases and very affordable.

I'll give it 5-stars after considering the cost relative to some other acceleration sensors.- Pairs nicely.- Good range of detection.- Optional siren is a nice feature.- Fantastic customer service.- Be nice if the siren disable and vibration sensitivity could be done remotely. These are done with switches in the device.

Turned the device on, heard the loud beeps from the "siren," immediately turned that off, then when into my Home Assistant installation and added this little baby to use for alerting me when my dryer turns off.However, there's a catch. The device, while I CAN connect it through the Aleca voice assistant integration, shows as unsupported for Alexa (as of May 18, 2025). Not a deal breaker, it just means I need to learn a little more on how to actually use Home Assistant (which was on my long-term to do list, anyway).I will be clear that this is not a deal breaker for me, as I love Third Reality's devices that I've tried so far, especially since they just work out of the box with ZHA, and I will continue to buy their products as the need arises.

I was a bit skeptical but had seen so many good reviews I thought I would give them a try. These use standard batteries, were easy to hook up, and do exactly what they say. I appreciate the sensitivity controls, and on high they pick up feedback very well. Integrations with other platforms (like home assistant) were pretty simple to set up. Highly recommend!

I bought two of these 3 or 4 months ago. One has been rock solid! The other I thought died because of battery, but after replacing the batteries, I've found out that it just plain died. I don't know why. I've taken the board out to inspect it, but I don't see any signs of any damage on the inside. All the traces seem normal. Idk. You might be hit or miss with these! 🤷‍♂️

I using this on my dryer to notity me when dryer is on and when finished in HomeAssistant.On the sensor itself I turned siren off and set senitivity to very high.I used Zigbee dongle and Zigbee2MQTT.So far been working great. Connected it with thin magnet strip placed it on back dryer.

I don't mean physically, I mean manually. The only controls you get through Zigbee are... nothing. I saw reviews discussing manually adjusting the alarm and that is not an option here, you can only physically enable or disable it. I could literally care less about the vibration part and just wanted a cheap alarm I can place in a few spots in the event of a break in. I might put it in my car as an additional security measure, but I can see that not working well either.Also right next to (an admittedly cheap) decibel meter it tops out at 74dB on VH settings, so it can't even be loud right.

Hands down the best vibration sensor I’ve tried for my smart home. I have one on the back of my washing machine and dryer and it’s sensitive enough to pick up throughout the cycles, but not so sensitive that it detects the door closing. Though I had to reduce the sensitivity on the dryer sensor because it was reading the washing machine next to it.With the ability to capture the X, Y, & Z axis at any given time I hope to use this to get into stupid and unnecessary levels of granular data because why the hell not? Overkill is underrated!Photos attached are from my test region in smartthings, I’ve not migrated to Home Assistant quite yet.
