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)

This sensor is part of a number of Yolink smart appliances I use. 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.

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.

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.

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.

All the YoLink stuff is good. I had to design and 3D print a bracket to mount this on my overhead door but that was no biggie. The app saw it immediately and it was working within a few minutes. I need to spend more time with the app as it would be great if I could set it to remind me the door was still open at night. Not the switch's fault, it works sweet!
