Review on 🔘 Aqara Vibration Sensor: Zigbee Connection, Wireless Glass Break Detector for Alarm System & Smart Home Automation. Requires Aqara Hub, Apple HomeKit Compatible, Works with IFTTT. by Steven Hanson

I use this to notify me when my mail has arrived. I keep it in my mailbox with velcro which is waterproof and when I receive mail it detects a vibration when the door is opened and closed. I also set up push notifications and an audible alarm from the M2 hub in my living room. I had an issue with the first one I bought where it would disconnect and wouldn't reconnect until I deleted it, brought it in, and synced it to the hub. I contacted Aqara support and they sent me a new one, no questions asked and the replacement was reliable! Two thumbs up for supporting Aqara! I love all of my other Aqara products and can't wait to see what else they come up with in the future.
