Works, But Limited Features
This sensor can accurately detect vibrations, but has a few issues.Installation in the Tuya app was pretty straightforward. I did have to get a pin and hold the reset button before the app would detect the sensor. After the sensor was added, it didn’t function properly until I installed the firmware update. After that, everything was fine.When testing this sensor, I was a bit disappointed in the response time. Perhaps I’m just used to zigbee sensors, but I wasn’t too excited about the delay between the sensor detecting vibration, and the status changing in the app. The delay was around 3 seconds, which isn’t terrible, but certainly not as fast as a zigbee sensor.The cool down time for the vibration status to clear in the app seems to be about 30 seconds. There’s no way to change this cooldown time in the app, which is also disappointing.I also integrated this sensor into Home Assistant using the Tuya integration (cloud not local). In home assistant, you get entities for vibration, tilt, and drop as well as the battery level. As far as I can tell, only the vibration entity updates. The tilt and drop entities don’t appear to be supported by the sensor.For the price, the sensor is acceptable, but I would probably recommend going with a zigbee version for a faster response time and direct integration into home assistant without needing to use the cloud.

Detects even the smallest vibrations
This sensor is a TUYA WiFi device so you can use the SmartLife App to add the sensor to your home control system. It will work with other Tuya devices as well as any home control system that supports Tuya. I was able to add it to my HomeSeer system so it can be integrated with more devices. To add it to your system, use a pin to press the button at the top of the unit. The LED will turn red. Then click the + button in the SmartLife App and it should be found. You need a 2.4 ghz WiFi network. Once added, it changes to a state of “vibration” or “normal”. As a test I mounted it to my dryer and then created a simple automation in the Tuya app that sent a notification when the sensor changes to “normal”, The sensor changes to normal when it stops. When the dryer is running, the device stays in the vibration state. Other uses for this are for detecting when a window breaks, or if an item is picked up and moved. If it’s too sensitive, you can change the sensitivity. There are 2 screenshots attached. One is from the Tuya App and the other is from the HomeSeer system.

Really cool sensor
These are really cool as a vibration sensor I attached them to doors and other areas that I want to monitor. I use this particular one for my garage door in the event anybody’s messing with it I will get an alert. Very easy to install and it provides me with added security which I like. All you have to do is peel up the sticker and stick it to what you want. Although this provides no sound the alarm system overall does

fonctionne très bien , installé sur un œil de bœuf avec une sensibilité au minimum et il averti sur téléphone avec l application tuya.

L’appli est un peu poussive mais dès que les appareils sont reconnu pas de soucis. J’ai réglé sur high.pas de fausse alerte.une seule chose l’alarme est sur votre smartphone pas sur les capteurs.

Der Sensor reagiert sehr empfindlich.Diese kann man aber auch in 3 Stufen einstellen.Das alles finde ich ausgesprochen gut.Und…☝🏻….er empfängt das W-Lan Signal auch über eine größere Entfernung.Kann das Teil empfehlen.
