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

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!

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.

Quick to pair to the Zigbee integration in Home Assistant, and the vibration detection is very good. I set the sensitivity to very high, placed it on the arm of my couch, and then lightly tapped the arm about 6 inches away, and it picked it up instantly. Motion state stays active for about 5 seconds after last vibration detected before returning to "Clear" state. Love that it uses 2x AA; with Zigbee sipping juice, this thing will last forever between battery changes.The only thing I wish I had known before purchasing was that it's rated for 0 - 40 C (32 - 104 F) and indoor use only. I had planned on putting it on my mailbox, but it definitely gets colder than 32 F here. Maybe I'll put it on the fridge and program the lights to come on or something. I'm sure I'll find a use for it.

I'm using this vibration sensor to detect when my dryer cycle is complete, a method widely demonstrated in various Home Assistant tutorials on YouTube. I appreciate the use of AAA batteries, as they offer longer life and allow me to use rechargeable ones. A helpful tip: make sure to turn off the siren before inserting the batteries by moving its dip switch from the '0' to the '1' position.

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! 🤷‍♂️

Bought this to automate when my dyer is running or stops and them send out a message so clothes don't get forgotten and left in the dryer to get musty and wrinkled. Smart Home Solver on YouTube has a video on how to make the automation using this sensor.

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.

I paired this THIRDREALITY vibration sensor with an IKEA DIRIGERA hub. It is seen by the hub as a motion sensor, and is exposed to Apple HomeKit and Alexa through the hub as a motion sensor; it was worked reliably for me with both platforms.The sensor itself has sensitivity and audible alert dip switches, so that it does not rely on software control for these functions. It takes two AAA batteries.
