I got this for my mailbox opening detection. I tried some indoor contact sensors but they do not have long range and I tried ring mailbox sensor (RMS). But I found out the RMS does not work well when I placed it in the back of the inside of the mailbox. I found out RMS is human heat based instead of detection of any object movement. With Yolink, I placed it inside a metal mail box and it works every time. Initially, the only problem I have is the sensor falling. I placed the sensor on a stationary side of the mailbox and the magnet on the back of the opening door. Maybe the door with the magnet hit the sensor. So I put some strong two sided tape on the sensor and placed it a bit further from the magnet (but need to be within 0.4 inch gap as specified). And I put one side of velcro tape to the small contact between two metal plates of the mail box so when the door is closed, the door will not slam each other and create vibration to dislodge the contact sensor. If it falls again, I will replace the two sided tape with velcro tape so I can remove it easily for battery change in the future. So far it works really well without falling. It works with Amazon Alexia well and it will pronounce "You've got mail". That is pretty cool. The software is pretty encompassing. It looked like yolink spent a lot of time on the software. After you get used to it, it is pretty powerful. I put another one as refrigerator door opening sensor. Each sensor can have its own alerting scheme if you wish. Both notify on my iPhone (you can select if the notification can appear in locked screen (critical alert) or just a banner on top of the phone or on apple watch. And it also alerts on Alexia, if you wish, "The refrigerator door is opened". And if it stay opened for a specified time, you can have the notification again repeatedly on the iPhone. It is pretty useful since the range from the sensor to the hub is very long so it works consistently. I like this purchase - easy installation, works well within metal, long range for consistency, comprehensive software, work with Alexia. I wish it works with Apple HomeKit but it seems like not for now.

This is a quality product. I purchased it because I have a detached garage with a house type door as well. With the app ,installation was easy. As for the usable functions, they are a little bit confusing, but figured it out with trial and error. It's connected through my internet and I have a couple settings to where it notifies if the garage door opens when I'm away and also during my sleeping hours. The other sensors are for my homes doors. The second the door opens, it's triggered, no delay. The 3M adhesion pads are great, make sure areas are clean. It's capable of doing much more through the app, but I just use it for my notifications for my doors when asleep.
