Review: 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: I have been using YoLink products for 4 years now. This is another great product of theirs. Simple to install, great battery life and does a great job of what it’s supposed to do. Best thing is the long range. No more worrying about whether your Wi-Fi signal is going to be strong enough, YoLink products use LORA, which is a low frequency, long range radio wave system that gives up to 1/4 mile range. I have YoLink sensors as far as 800’ from my hub and no problem. With the 40 or so YoLink sensors I have, I’ve had to deal with YoLink tech support a few times and have always found them to be over-the-top excellent in their response, even going so far as to send me replacements as long as several years after my purchase. I’m an electrical engineer with a specialty in digital communication and I design radio frequency communication products among other things. I have nothing but good things to say about YoLink products and support. I have over 180 smart products of various brands in my homes and boat and YoLink products are among the easiest and best. Their app is also very comprehensive and feature rich. I use this contact sensor to interface some of my own circuit boards with my IoT devices.

## 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.

*by C***S on 13 July 2025*

great security feature that doesn’t cost a fortune. Extremely easy to add via the QR code on the product. The signal is great given the hun is in the basement while the door sensor is on the shed 18 ft from the house. Works extremely well and is a great add on to the other sensors/monitors that I have operating. Definitely with its price. Highly recommended.
