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)

Works well, randomly says its open when its still closed. Alignment is correct for the magnet and sensor.

I've been looking for something like them for many many years. They are one of the best things to tell if someone is sneaking in your house whenever.

Rated only 3 stars for a reason. It consistently tells me the door has been opened but only intermittently registers that the door has been closed. Because of that Alexa integration is useless as Alexa always thinks the door is open. Seller sent a replacement but same issue. Seller wasn't helpful after that, just spoke in circles and was condescending.

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

Muy buen sensor para intrusos o personas no identificadas en tu apartamento, lo único malo es que no hay manera de desactivarlo cuando estás entrando y saliendo por algo que estés haciendo en el auto, por ejemplo, si no que cada vez que abres la puerta, se activa la alarma en el celular, pero por lo demás, está excelente.

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.

Keep in mind that after about a week, you’ll no longer have access to the benefits of the initial product. To continue receiving notifications and other features, you’ll need to pay an annual fee. Otherwise, it will function only as a basic door alarm.
