2-Pack Smart Door and Window Sensor, 2.4G WiFi Door Sensor, Tuya/Smart Life Contact Sensors for Home Security & Smart Home Automation, Compatible with Alexa Google Assistant

VERY simple to install and easily integrated into the Tuya / Smart Life app. The sensor mounts with a couple small screws and the magnet half has some sticky tape. Super easy just with basic tools. A small blue LED briefly lights to let you know the sensor has been triggered.I use these to notify me whenever a door is opened after hours. Works great! Even tells me the battery level and alerts me when low.I would buy these again if I need more door/window sensors.

It is absolutely ridiculous that this thing claims to work with Google and Alexa. At minimum all it does is offer you the ability to ASK Google or Alexa if the door is open or closed.you cannot set automations for when the doors open and closed to have Google or Alexa say or do things. Its ridiculous to claim it works with Google. I just wanted something that would have Google announce when a door is open or closed. But nope, it does not work.Awful product, Buy the cheap ones that beep when the door is open or closed.Also, it’s so sensitive that you can barely have the two components on separate height levels. So unless your door or window is perfectly flat, and this is gonna be a hassle to install.

I love these door and window security system. These work perfect for rentals. The app is downloaded on your phone and gives notifications when they are opened!

The devices work great and were pretty easy to setup. That said, the backing foam tape to attach these to the windows will only hold for 24hrs. I was a little freaked out when I got a notification around 3am in the morning that my sliding door was opened. Come downstairs "well armed" to find nothing and the sensor on the ground. Later that day I get another notification another window was open when I wasn't home, and again the sensor just fell off. Just to be clear I properly clean the the window where these sensor were attached with rubbing alcohol so that wasn't the problem. Just junk foam tape is provided. I replaced it with some 3m double-sided tape and there has been no issues for weeks now. So these sensor are good but if you are going to use them use a better double-sided tape than what is provided.

The user interface for this is terrible. The app isn't the most stable, but when it does work i get alot of false alarms.

These work perfectly and connect with Alexa for routine notifications.

Setup was easy with Smart Life. The description says "the sensor will push app notification alerts to your smartphone", but the only way I can see that happening is if I pay extra for it. I would look elsewhere for door sensors. If there is a way to get notifications without the extra cost please let me know and I will update my review.

Good product. I would not rely this as an alarm, but more to check in to see if there has been any activity.
