Review: Yo-link - Features, Range, Extenders, and limitations - Yo-link - Features, Range, Extender, Limitations PRO Features Diversity of product line Integration capabilities as a smart home device Low cost Battery Life CON 1/4 Mile range advertised likely clear line of site In wooded area reliable range was more like 300 feet Antennas, range extenders not available Unsupported range extender works but limits features Some limitations For house monitoring of crawl space temp/humidity, water leak detection, motion in attic etc., the product line works extremely well and has excellent smart home integration. The goal was to simplify install, minimize/eliminate wiring for sensors, and to gain smart device capabilities. When working for external device monitoring such as driveway gates, package delivery box notification at a range of 450 feet through wooded areas challenges were uncovered. For the package delivery box, the original concept was to mount a garage door sensor flush (horizontal) on the bottom of the lid that would toggle when the lid was opened. From what I could glean the device is designed to be installed on the inside of a garage door (vertical) with door closed. There was not a software option on this sensor to alert on normally open vs normally closed. Therefore a bracket needed to be assembled to mount the sensor in a vertical position for the device to operate. Would be nice if the device offered this option. During the process the range was learned to be a challenge. Moved hub outside, tried different orientations to try to optimize internal antenna (vertical / horizontal) different sides facing device and was not able to mitigate signal limitation. Yo-link does not offer an antenna, and/or range extender. Found a helpful "non-supported" solution to create a signal relay solution. This uses a yo-link Security Siren & Alarm controller and yo-link Outdoor contact sensor. Between these two devices a relay is required. I found and electronic relay with NO normally open and NC normally closed output contacts; "OONO DPST 1NO 1NC 8Amp Power Relay Module, AC/DC 12V Control Voltage" which worked perfectly. Configure the remote device to trigger the Alarm controller. Replace with siren with the input to the relay module. Attach the contact sensor to either the NO/NC contacts as appropriate for your project. This solved the range issue in this case. However, the ability to monitor if the device remains open and is not closed is lost. A goal was to add this solution to the driveway gate and obtain a notification if the gate was not closed. At this time I do not know a solution to the range challenge combined with some of the additional features yo-link offers. I am using these devices outside of their intended design, so I will still rate them highly. However, it would be nice for yo-link to have an extended range solution that supports all of the device capability as well as a tilt sensor (garage door sensor), that allowed the NO/NC configuration to be modified. Overall I have been impressed.
Review: Save time from walking to mailbox for nothing - My mailbox is about 154 feet away from my house. 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.

## Questions & Answers

**Q: Any advice on how to use sensors on a metal mailbox? 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.

### ⭐⭐⭐⭐⭐ Great product for outdoor door/gate scenarios.
*by N***R on December 6, 2025*

Needed a solution to add outdoor sensors for some farm gates that are not visible. Added these to the YoLink app, then presented to home assistant, then via that presented that to Apple HomeKit. I get notifications on my iPhone , and set up automation to pop up camera feed when the gate opens. The range is great, one gate is 300 feet from the hub and still works like it's 1 foot away. Surprised to find that the Hub connects to wifi or wired which is a great plus, as I prefer wired for backend infrastructure. Sensor uses the basic aa battery box with cookie jar like plastic latches. Think battery operated fairy lights or Christmas lights. I am concerned about its durability in the summer, we will see as it gets very hot where I live and these are black plastic. So far the product does exactly what it's supposed to. A simple contact closure that is weather proof that uses regular ol batteries. Also discovered you can use a larger stronger magnet for a bigger gap.
