DEVICE-TO-DEVICE PAIRING: a unique feature, two or more devices can be paired together. Even if the internet is out and the power is down, they will carry out their paired actions. Pair your door sensors to a Siren Alarm, then turn it off when you want to “disarm” your system. Use a SirenFob or FlexFob to control your siren. Make your own custom security system!
DON’T TRY THIS WITH WiFi! LoRa is short for Long-Range. Boasting up to a quarter-mile open-air range, and operating at the 900 MHz band, YoLink devices can be placed where your WiFi probably can’t go, such as in basements, separate buildings, even on RVs and boats stored on your property! Prepare to be pleasantly surprised!
Requirements – Android or Apple smartphone, wired ethernet port or stable WiFi connection (2.4 GHz band, only).

Unbeatable Reliability! The YoLink LoRa Smart Door & Window Sensor is a Game-Changer!
I’ve been slowly building out my smart home, and when it came to securing my doors and windows, I wanted something truly reliable. After trying a few other brands, I decided to give the YoLink LoRa Smart Door & Window Sensor a try, and I am absolutely blown away by its performance! This sensor has quickly become the cornerstone of my home security and automation.The installation was incredibly simple. It took me less than a minute per sensor to attach them to my doors and windows using the included adhesive. Pairing them with my YoLink Hub was equally effortless, and they were recognized instantly. No complicated wiring, no fussy setup – just quick and easy integration.What truly sets this sensor apart is its use of LoRa (Long Range) technology. This is not just marketing hype; it genuinely makes a massive difference in range and reliability. I have sensors on detached sheds and gates at the very edge of my property, and they connect flawlessly to my hub inside the house, something other smart home devices struggled with. I get instant notifications on my phone every time a door or window is opened or closed, without any dropped signals or false alarms. This consistent, dependable performance provides immense peace of mind.The battery life is also exceptional, thanks to LoRa’s low power consumption. I haven’t had to think about changing batteries since I installed them, which is a huge convenience compared to other sensors that drain batteries quickly.I’ve integrated these sensors into various automation routines, from turning on lights when a door opens to triggering security alerts, and they perform flawlessly every single time. The YoLink app is intuitive and provides clear status updates for all my sensors.In summary, if you’re looking for a smart door and window sensor that you can truly depend on, with incredible range, rock-solid reliability, and effortless installation, look no further than the YoLink LoRa Smart Door & Window Sensor. It’s a premium product that delivers on every promise and is an essential addition to any smart home. Highly, highly recommend!

It works well for metal mailbox opening detection
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.

Long story short, these two guys came to my house to clean my heating ducts and started to make really weird jokes about how they could rob me of my stuff and then resell it back to me. I didn’t like that at all.So I came to Amazon to see what sort of solutions existed in this day and age, before I considered getting a professional home security system that you pay for every month etc. Yes, that option is by far the best if you want 100% peace of mind.That said, I wanted to give this product a try and here’s what I have to say about it:PROS = everything is relatively small so it doesn’t take up a bunch of space. The piece that connects to your router is the size of a smoke detector and can be set up on a wall, or leave it on the floor like I did, next to the router. I plug it in with the cable rather than WIFI, it’s that much more reliable that way. It comes with 4 detectors, which is exactly how many I needed (2 windows and 2 doors).Once you’re set up, you have to go into the app and click a few times to get to the alarm scenario you want to activate once you’ve left your home. Sometimes the app takes a few more seconds to launch and find your scenario.I absolutely love that I can see the situation anywhere I am, you can see in the app the status of each detector. I also love that I was able to get notifications sent to my smart watch (it sends an email if something is going on)!CONSSet up is wonky and rather unintuitive. Others have said so too. I spent more time than I wanted to on the software setup. IMPORTANT: don’t do what I did, scan each detector BEFORE you stick it to the spot!! I installed a detector (after having to modify the door frame because it didn’t fit naturaly) and then I had to scan it to include it in the software and I couldn’t get my damn phone to see the QR code properly – and once you stick it to the door or wall it’s over!!Also important: even though it has really good sticking glue some of the detectors eventually fall off. I tried hot glue and what not, nothing seems to work. I resorted to ugly black electric tape and so far this is the only thing keeping the detectors in place, for the ones that come off. It depends on the surface, and you should probably up your chances of success by cleaning the surface before sticking them on, which I did not do.I bought the siren alarm to go with it, the sound is alright but not scary alarming loud.Am I happy so far? YES! I can see what’s going on when I’m away, I get prompt warnings if something is happening, and once the set up is figured out you’re good to go.

A great addition to my home automation and security system.

Like all YoLink products it’s very high quality. Works great to detect an open door or window. In my case I used it to remind me if I left the shed door open or if someone opens it in the middle of the night.Range is fantastic. Way better than wifi – will work even from a block away or more.The only thing I don’t like about this (and many other YoLink products) is that they attach via double sided tape. Yes that’s easy but in my case the magnet part eventually fell off the wood door. Why can’t they provide screw holes? Such a small design decision that would have been really helpful. Not enough for me not to recommend it but really I expected to be able to screw these on if I wanted.

Fast response, good range and good tolerance on the magnet position. I wanted 4 sensors which they do on the Yolink Website, but not Amazon. As a UK user the postage from the USA would have been expensive, so ended up buying 3 + 1.
