Outstanding long-range performance!

The LoRa technology provides incredible range that puts other smart sensors to shame - I can monitor doors and windows from anywhere on my property without signal issues.Installation was incredibly easy - just peel and stick, then pair with the app. The magnetic connection between the two pieces is strong and reliable, and the compact design isn't obtrusive on door frames or windows.What really impressed me is the instant notifications. The moment a door or window opens, I get an alert on my phone - no delays or missed triggers like I've experienced with WiFi-based sensors. The battery life seems excellent too, which is crucial for sensors in hard-to-reach places.The app interface is clean and intuitive, making it easy to set up different notification schedules and monitor multiple sensors. Perfect for security monitoring or just keeping track of which doors/windows are open.For anyone wanting reliable, long-range door and window monitoring without the connectivity headaches of traditional smart home sensors. The range and reliability make it worth every penny!Finally found smart sensors that actually work consistently throughout my entire property!

Minimal testing but I love it so far!

Just installed but so far I love it. I was worried it wouldn't connect because I'm on the 2nd floor and I have one for my basement, but the app tells me I have a strong signal, which is awesome information to know. Through testing and while on wifi, it notifies me almost instantly. I can set it up to notify right away, or wait a few seconds, and whether or not it notifies me just through the app or email and SMS as well. I really like the options on the app. Setting up scenes is a little confusing, just the way things are worded. I'll come back and edit if it sucks when I leave the house, but so far so good!

working great so far

Doing what they do....Well.Yes I recommend you buy these along with the Yolink hub.So simple to install.They just workSorry no long term review.------------------------------Oh... here are a few details about Yolink sensors and hub you really do need to know.All yolink sensors of any type communicate with the hub and the hub communicates with the yolink server and the server communicates with your cell phone and the yolink app.You might think this is bad but I actually love it. Here is why.You link can send you a text or an email if a sensor is tripped. But if that text or email winds up on your phone how do you know it got there? Does your phone make some special beep when a yolink email comes in or a special sound when a yolink text comes in? As for the text I do know how to customize my text to make a special noise but I don't bother.Why don't I bother? Because I set the yolink app to "app only notification".Well ladies and gentlemen.... I found a notification reader app for my phone. It reads yolink notification out loud. Not text, not email but app notifications from the yolink app.It can be set to only read notification from any certain app you want and not from apps you don't want.Get this... it has a time delineation setting.... LOL your thinking WHAT? No it does not delineate time...It delineates THE time the app reads notifications out loud.Here is how I set it, I have it set so the app reader only reads yolink notifications at night. Not during the day time. My wife hates hearing it during the day and evening. During these times the notification makes a small sound. I know to check the notification. My wife can't hear it.So get all that? Yolink could have an "in app reader" or "announcement" that could simply say out loud what sensor just got tripped. But yolink wants you to pay them for a text service that can send a lot of text to you.NO... you don't need that.Install the notification reader, it is called "voice notify" version 1.3.1, it is awesome.It truly completes the Yolink system and makes it what it truly should be. A way for your phone to tell you what door or window or yolink sensor just got tripped and it can happen while you are in your easy chair at home, or, in an airport on another continent on the other side of the planet.~
