It performs perfectly, reliably, and installed relatively easily. The electronic part of installation is easy, as part of the Yolink suite of sensors. The mechanical part was relatively easy. I'm using it as a steel gate monitor, and it apparently is intended for wood gates and doors, so the included wood screws weren't used. In my case, to mount the unit I super-glued the magnet portion to the swinging gate and zip-tied the Hall-sensor portion to the static frame of the gate. It is AA battery operated, and batteries were provided. It has been in place for nearly a year and it has worked without missing an opening of the gate or alarming for a false opening the entire time. it maintains a history of openings and closings. An Open reminder can be set, so the user is notified if the gate remains open for a settable period of time. This feature is the primary reason I purchased the unit. After nine months the battery level shows as full. The signal intensity also is shown by the app, and it shows Strong (-59 dBm) in my case where the receiver is 25-30 ft away and inside the house. The receiver (hub) connects wirelessly to my AP. As with all the Yolink sensors, I have no complaints. The cost was reasonable for the quality, reliability, and satisfaction it provides. Review: Yolink has very good products. Great range. Great battery life. Very good quality - Works great, room for error as can have a large gap in between sensors upon install. The smaller sensors have to be very tight to work properly, too tight Batteries last a long time, and very well built. A good value as this should last a long time. Also, I love that they allow us to replace the batteries in virtually every one of their products, this is so cool not to have to charge each one and then replace the whole unit due to a dead rechargeable sealed battery that cant be accessed. Issues with Yolink: first their app would send push notifications and worked great on my old Samsung phone for a few years but the s25 phone upgrade works some weeks and others not intermittently for no apparent reason, so not ideal for security. Ive contacted them about this with no solution. I have spent over 1000 dollars on yolink for house automation and security so not a good thing to have intermittent notifications. Also, Yolink should make both a carbon monoxide detector and smoke detector, I have heard others mention this.. Lastly, we should be able to organize our devices in the app to keep all the same categories together. For instance sensors together, cameras in another area etc... It would be much more efficient. It should be easy enough to program a way to move the icons around in the app to group them together or a auto list by name, date downloaded or type. I would be happy to be a product tester for YoLink as I think they are a great company with great forward thinking products. ## Features - PROTECT YOUR PERIMETER and prevent crime at your property line!

The metal seems to be disrupting the magnetic sensors from working.** A: I would mount the magnetic sensor INSIDE the metal mailbox, route the wire thru a small hole UNDER the mailbox, and mount the TX transmit device inside a small weather proof external plastic box.this could be mounted on the side of the post holding the mailbox, not seen from streets. The cost would be minimal. The sensor would take up minimal footprint inside the mailbox, the wires secured/routed to the mailbox metal via silicon glue, keeping them out of the way. This is what I would do, personally. Hopefully, this will give you ideas to consider. **Q: Is it there any picture of the product installed?** A: Yes, we have an installed picture. Please kindly contact us for more information. As for the installation of the Outdoor Contact Sensor, please kindly refer to the following guide http://www.yosmart.com/support/YS7707-UC/docs/instruction **Q: Can the " open too long" feature be disabled for part of the day?** A: You can customize an alarm strategy for the YoLink contact sensor, turn on the "Do not disturb" and set the time you do not want to receive notifications including the "Open Remind". **Q: how long are the wires?** A: It's around 12 inches. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It's very useful, has proven reliable, and is low-cost for what it is and does *by J***D on April 27, 2026* This sensor is part of a number of Yolink smart appliances I use.

My mail delivery times vary, it can be anywhere from 3 pm -10 pm. I used to check it when I got home from work and found nothing, but I know I have mail due to the USPS Informed Delivery I signed up for. So I would need to keep checking the mailbox until either I got the mail or just went to bed and I would get the mail the following day. So I wanted something that would alert us when the mail was delivered. I did an internet search and I found this YoLink LoRa Smart Outdoor Contact Sensor. I read reviews and watched YouTube video reviews of it. As I was reading a review and saw that someone decided to go a slightly different route and went with the YoLink LoRa 1/4 Mile Wireless Range Smart Motion Detector. They placed the motion detector inside and on the back of the mailbox. I was going to follow because I liked the idea of the lack of any wires but then discovered the motion sensor does not work in cold weather (32 degrees is the lowest operating temperature and I live where it is colder during the winter months). So I went back to the idea of this, YoLink LoRa Smart Outdoor Contact Sensor. I bought the YoLink LoRa Smart Outdoor Contact Sensor with Hub. It was easy to set up. I downloaded the app first and created an account. Then I plugged in the hub and connected it to my router (via ethernet cable, it can be connected wirelessly but I like the wired connection, less chance of any issues), and then I added the contact sensor to the app. I tested the sensor first before installing it on the mailbox. When I was planning my installation on the mailbox, I saw that some installed the sensor inside the mailbox, but I did not want the sensor to get bumped by any mail or packages, so I decided to place the sensor on the outside. I also wanted to have easy access to the battery box. I wanted to easily remove the battery box from the mailbox, so I did not want to tape the box to the mailbox (underneath the mailbox). So I used the double-sided tape that came with the sensor and taped the battery box to an 11 lb round magnet (it takes 11 lbs of force to remove the magnet, the magnet does not weigh 11 lbs). With the magnet on the battery box, I can place the battery box anywhere on my metal mailbox and it is secure enough that it will not fall or detach itself. It is a solid connection. I placed the battery box underneath the mailbox where it is not too noticeable. I installed the sensors in the door area of the mailbox with double-sided tape after I wiped the area with rubbing alcohol for a clean surface. Once the sensor and box were installed, I then went into the app setting and set up the alerts. I wanted app alerts when the mailbox sensor was opened. At first, I did not get alerts, but then I realized I had to go into my phone app settings and give permission for the YoLink app to give me alerts. Once I did that, it was working great. I work in a different city and I will get notified via app alert that my mailbox has been opened. This system was easy to install and use. It is easy to add more sensors and devices. A hub can have more than 200+ devices connected to it, plenty if you want to add more devices for home security. The only critical thing I can say about this is this has an option to get text alerts if the the sensor is opened, but you only get so many texts a month and you will need to pay to subscribe to get more text alerts. But with the app alerts, it is limitless and it alerts me. What else can you ask for? You can get email alerts as well, but the app alerts work great for my needs. ## Frequently Bought Together - YOLINK LoRa Smart Outdoor Contact Sensor, Gate & Shed Door Sensor, Universal Contact-Closure Sensor, Email/SMS/Push Alerts, 1/4 Mile Range, Alexa, IFTTT, Home Assistant (Hub Required) - YoLink LoRa Smart Door & Window Sensor 3-Pack: Door Left-Open Reminders, up to 1/4 Mile Open-Air Range, up to 5 Year Battery Life, Alexa, IFTTT, Home Assistant --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/261111406-lora-smart-outdoor-contact-sensor-gate-and-shed-door-sensor](https://www.desertcart.tn/products/261111406-lora-smart-outdoor-contact-sensor-gate-and-shed-door-sensor) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-19*
