I bought this to install in my mailbox so I can see when my mail arrives. I had to get a newer Revain Echo (spherical) to have a Zigbee hub. I couldn't figure out how to connect this through the SmartLife app and I would have tried my best, but I was able to see the connection through the Alexa app using Find Devices. I then set up a notification and named it "Mail in" in the Alexa app. So when it detects motion, I get a "Mail in" notification. There is an automatic reset delay of a few minutes between notifications, so I usually only get one notification. I don't think there is a way to change the delay time. My mailbox is about 20 feet from my Echo/Zigbee hub. It works fine for me, but I had to put foam pads on the mailbox door because the wind caused a lot of false alarms. It's safe now. This is a great product for its purpose. I can't say anything about the battery life yet.
