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.

These work great, i have indoor ones too. Waiting to see how long batteries last, so far indoor ones havent needed changing. I use in 4 of our outdoor gates and 4 indoor, closet, liquor cabinet etc. 5 stars forsure

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.

Works great, but they expect you to use a sticky to attach this. That does not work on an outside gate. At the very least everything should have mounting holes for screws. Apart from the mounting kerfuffle, it works great.
