    • Easy to install, works over long distances, internet accessible
Style: 0 dB
So many other 'connected' devices have difficulty with distances. I had a Z-Wave based system that was unreliable because nodes would randomly disconnect due to poor signal strength due to distance or interference (every time it rained, my system went down). YoLink uses LoRa technology which has fantastic range capability up to 1/4 mile and this solves the disconnection problem completely. They integrate Semtech's LoRa RF Module. Everything is ultra low power so sensors can run on batteries for many, many months. The whole YoLink system depends on a YoLink hub, that receives/transmits LoRa signals from/to various sensors and actuators. The hub is connected to the internet through your WiFi or ethernet system. An app, residing on your smartphone, is used to control and monitor all devices connected to the hub and even tells you how each sensors battery is doing. I have several YoLink modules (garage door kit, moisture sensor, motion sensor, siren). They have all been VERY easy to set up. I would say that compared to other technologies (ZigBee, Z-Wave, ...) Yo Link's implementation using LoRa paired with their app has greatly reduced issues with initial setup. The garage door controller kit took all of about 5 minutes to install and test. The garage is detached from my house and is a bit of hike from the house. The LoRa radio shows 'good' signal availability at the hub in spite of the distance. I simply could not have done this with almost any other technology. The app is integrated with with IFTTT which allows you to create smart automations that can integrate with the Alexa personal assistant. This is a very nice capability to have. I had one small issue with the motion sensor (setting the sensitivity) and was really pleased with how quickly and efficiently their technical support dealt with that minor issue. We were having some work done at our house and a contractor had stored material in the garage. I was able to remotely open the garage to give him access to the material and then remotely close the garage when he was finished. The app also warns you when the garage door has been left open after a timeout. If you're the kind of person who worries about whether you shut the stove off, you'll appreciate the YoLink Garage Kit (door position sensor, door opener Controller). The controller is, in essence, an app controlled relay that emulates pressing the button that usually opens the garage door. It's foolproof! The modules are made of good quality plastic and some are even weather sealed (moisture sensor for example). My experience with YoLink has been excellent. The LoRa radio modules do exactly what YoLink says they do: allow communication over long distances that other technologies cannot deal with. Low power is another very critical feature of their modules. It means you don't have to change batteries very often. My system has been ultra reliable and easy to use. I admit, though, that some of the messages that the app shows are not what anyone would call 'grammatically correct English'. Also, the colors (pastel shades) chosen for the graphics in the app are low contrast and difficult to see in bright sunlight. Overall, I give YoLink 5 stars. Great apps, great prices, great support, great features. It just works! ... show more

    • Great Product Line
Style: 0 dB
After many hours of research, decided to go with the YoLink product line. Purchased the hub, water sensors, water valve controller, a couple of the outlet controls, motion sensor, and a door sensor for the garage door. Really well designed system, completely wireless with long life batteries. The app is free, so no subscription costs and very easy to use and alerts are sent right to your phone. Paired the water sensors to the water valve controller and tested by pouring some water under a sensor - worked perfectly, sensor trigger the water value which turned off. Really well designed product line. ... show more

    • Perfect when combined with smart shutoff valve

The smart hub was really easy to setup. It was truly plug-n-play. All I had to do was connect it's ethernet in one of my mesh access points (it just needs to be connected to any empty LAN port in the router/gateway). I waited for the lights to get stable, I then scanned the QR code on the device and it got added to the app and showed up as online. For each sensor, all I had to do was just push the set button once and within 20s they became online. I then scanned the QR code on them and added them to the YoLink app too and finally connected the YoLink account to my Google home so I can manage all these devices from my hub or voice assistant. I also added my smart shutoff valve that i had purchased separately to the app by scanning QR code on the valve controller and now if any of the sensors detects a leak, the valve controller will shutoff the main line to prevent flooding or any major water damage. As compared to all other products in this segment, YoLink offers best features at best price with simple DIY installation and no monthly subscriptions. The app is perfect and the devices had no glitches during setup otherwise I've never seen any smart device getting setup so easily and I can say that by experience having 100 plus IoT devices, smart appliances etc. in my home. I would highly recommend them. ... show more
