WiFi Door Sensor: Smart Door Open/Closed Detectors, Wireless Window Sensor with App Notification Alert, Contact Sensor for Home Security, Compatible with Alexa Google Assistant (1pack)

The good:- The device makes no sound- The magnet pull is abysmally weak, so while it's nothing that you need to push/pull through, it still works- 2 AAA batteries - easy to replace- The notifications and alerts *generally* work reliably- It's relatively small. I feel it cold be smaller, but adding in the AAA battery compartment, it makes a bit of sense that it's notThe bad:- Requires an app. Not necessarily obtained through third-party sites. I actually got the app first before the device.- Adding the device to the app is a bit painful. You'll likely need to do it twice (to familiarize yourself with the process the first time) unless your phone is setup to grant absolutely all permissions to everything immediately- Alerts work, but by default, it's the most obnoxious and urgent-sounding alarm... for a door being opened/closed/low battery. NOTE: This uses "alert notifications" not "notifications", so on glorious Android, this can be altered to your liking pretty easily so that you have a distinct, calmer, alert notification sound for this app- There's a flashing light. I understand that it needs to have some level of direct communication, and it's small enough to cover with tape or something, but still. When I get things that start beeping and flashing, my first goal is to prevent them from beeping or flashingThe Ugly:- The app refuses to work unless you grant location permissions - PRECISE location permissions. This is apparently a one-time thing, as after setup, you can remove the permission. The app cries about it, but will continue to work.- You cannot connect this bluetooth/wifi device with only bluetooth. You need to give it (via the app) your wifi password.- Many features you'd expect, like alternate notifications outside the app cost additional money on a subscription basis. I'm fine with just the app notifications, personally. Get a notification forwarding app if this will bug you.- If you are looking into this product because you want to stay away from Tuya, I have some bad news for you.- Made in China

The title says it all. The device works exactly as intended. I had no trouble pairing it with the Smart Life app and has had great connectivity. My only complaint is that the device is much larger than I anticipated based on other contact sensors that I have.

Have had Zero issues. Set up easy and never fails to function. Good purchase. 3 doors and buying for garage entry door too.

Once you get it synced it's all pretty straight forward. Take a couple of seconds, I have the Amazon Alexa app push notification when open and works consistently.

This Wi-Fi door sensor gets the job done and works flawlessly once you get it set up. Installation was straightforward and quick, but I found the setup process a bit confusing, mostly because the instructions were poorly written. A clearer manual or better-designed app would definitely improve the experience.That said, after navigating through the initial setup, the sensor has performed perfectly. It’s reliable and responsive, and I’ve had zero issues with Alexa integration. The door open announcements work seamlessly, which has been incredibly helpful for monitoring my elderly grandmother, who sometimes gets up in the middle of the night.Overall, this sensor is fully functional and dependable after you get it up and running. If the company improves the app and instructions, it would easily be a five-star product. Still, it’s a great purchase if you’re willing to spend a bit of extra time on the setup.

horrible, don't buy please doesn't even go off. Doesn'twork not worth your money. It was a waste of money and gas to return it. The appthey gave you doesn't even work. I had to wait 2 days to find the app. Even then doesn't work.

I use this to monitor the comings and goings of an elderly family member who lives alone. The best things about this device are it works, it doesn't need a hub, it's inexpensive and it's easy to sync the device to the SmartLife app. It's a simple solution to monitor the door. On the app, you can choose to get the audio alarm and notification on your phone when the door opens and/or closes; there's no sound from the device itself. You also get a record of when the sensor is turned on (when the door opens) and turned off (when the door closes). The cons are you cannot independently adjust the alarm volume on your phone and you have to buy the services for SMS or Phone notification.

Alerts your phone to open door but there is nothing audible
