THIRDREALITYZigbee Vibration Sensor with 110dB Alarm, Zigbee Hub Required,Adjustable Sensitivity, Create Routines,Compatible with Home Assistant via ZHA/Z2M and Echo Devices with Built-in Zigbee hub

Excellent Zigbee vibration sensor, although much larger than others I've used, but that's fine by me since it uses much more readily available AAA batteries.Could not have been easier to setup in Home Assistant, I literally told Home Assistant to scan for new devices and pulled out the battery tab and it appeared right away.I could not quite get my head around the sensitivity switches at first, so I set it totally the opposite to what I wanted, so if it doesn't seem sensitive enough just swap the switches.

Ridiculously difficult to open to get access to the switches and batteries but it works well. The 'siren' is a few fairly quiet beeps.

Only clear or detected motion and not sensitive enough to small vibrations.More a movement sensor.HA using ZHA through Zigbee only has clear or detected entities.OK for the price and if only movement is wanted but as I was hoping to sense the vibration changes on my 3D printer, this can't display that level of detail, at least not with ZHYA.I must try 2MQTT one day as there it may have more entities.OK for the price so 3 stars.

Handy item works well with Alexa but had to add additional siren and smart switch because of pathetic 85db noise

I bought this to replace an Aqara vibration sensor as I had heard good things about this. The device is certainly more responsive than the Aqara, however, the batteries that came with it died within a week. This is just a little bit sooner than the much smaller Aqara that can last a year on a coin battery. I thought it was an issue with the no-name brand batteries supplied with it so I replaced them with better ones. Two days later and we are down from 98% battery to 94% and dropping. The alarm isn't on and the device it is attached to hasn't been used in that time. Even then I would still expect the device to be more energy efficient than this. Ultimately, you get what you pay for and cheaper is not always better.

Honestly, works great. Tales 2 AAA batteries so not the smallest unit, but slim.Connected straight up to home assistant and works quickly. Has around a 5sec cool off.The siren is not a siten, just a fairly quiet beep at a couple of meters away. Definitely does not sound anywhere close to 110db so I am not sure how they measured that. I wish it was a siren.

Habe mit dem Sensor unsere Haustür-Klingel Smart gemacht. Der Sensor läuft bei mir ohne Probleme über Zigbee2MQTT in Home Assistant. Sobald jemand bei mir an der Tür klingelt, kriege ich eine Benachrichtigung. Man kann die Empfindlichkeit direkt am Sensor einstellen.Ich bin bis jetzt sehr zufrieden, da er sehr zuverlässig läuft und schön ist auch, das keine Knopfzelle verwendet wurde.

L'unico sensore che si connette direttamente ad echo gli altri necessitano di hub. Funziona bene per ora

Installé sur une porte extérieure, ce capteur de vibrations relié à une passerelle zigbee et à l'appli smart life permet de détecter toute tentative d'effraction avant même que le détecteur d'ouverture de porte n'entre en action.La sensibilité de détection est réglable (4 niveaux).Dispose d'une alarme sonore que je n'ai pas activée donc pas testée...

Funziona benissimo ottimo prodotto

Wohl eher 11 dB
