  • Great Product Line
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

  • Super easy to set up, seems very reliable.
This is a review of the 4 sensor with hub and no audible alarm. Very easy to set up - plug the hub into your router LAN port, connect the power with provided USB cable and power adapter, install the app. Using the app, scan the QR code of the hub and then you're ready to add each device by simply turning it on and scanning the QR code on the device through the app. Worked flawlessly for all 4. The app seems intuitive enough to use, and can be configured for whatever kind of messaging you want -- eMail, SMS, and push notification to your phone. Tested all 3 modes and works fine. The sensors themselves can detect water being sprayed on top ( 1 sensor) as well as pooling water underneath (2 sensors). Through the app, can also see the battery level on all sensors as well as connection status. Only thing is the range probably isn't anywhere near 1000 feet in reality. May be sufficient to cover garage and outdoor shed perhaps, but couldn't work when I put a sensor inside my neighbor's house across the street -- too many walls for signal to go through. Anyway, works in all rooms of my 2-story house, so I'm very happy with the product. Hope I never get a message from it! ... show more

  • Awesome - fast set up, works with Alexa, works without internet!
Review Summary - Awesome I recently purchased the YoLink Hub and Water Sensor pack on Amazon and the YoLink 3/4 motorized water/gas valve shut off from their direct site. All products worked fantastically. I was not thrilled with the idea of yet another hub in my Smart Home but the reviews (and no availability of SmartThings water sensors) led me to try YL and I am so glad I did. I love this brand now: set up was faster than zwave/zigbee, works without internet, and flawless integration with Amazon's Alexa. 5 Stars hands down and another 5 for the future - make sure to follow them on FB. Below are some other things I would like to share. When to buy water sensors - Every time someone shares a wet story A couple of years ago, my cousin's house flooded after his girls filled the sink with water (washing their face like they down in the movies) and then left for school... He had to live at my parent's lake cottage for the winter (~3mo) in upstate NY. Family of 4, dog, and cat in a 2 bedroom ranch with no laundry. At that time, I decided that since their deductible was $500, I was going to spend that much on a solution: a dozen ST water sensors and a Dome bolt-on valve control. Every time I have a water issue, a close call, or hear a story about someone who had an issue - I buy a few more. The latest was a co-worker whose parents went to Florida for the winter. Apparently, a bird died in their HVAC exhaust pipe, slide down, and errored out the furnace (CO2 protection feature). Since they had no smart devices to warn them about the cold house, the pipes burst and no one knew. When they came back 3 weeks later... eww. That's when I found and joined the YoLink system! Use Cases - Start low in each room I am not a plumber or insurance claims agent: these are just my thoughts that work with my house. I first started out with 1 water sensor in each bathroom. I put them by the toilet with the thought that if a sink also had an issue, at some point it would make it out of the cabinet and onto the floor and get to the sensor. It won't help with small leaks that will just go through the cabinet and into the floor/ceiling etc, but it's a start since water damage can happen almost anywhere. You can always go back and add another to each room (see above "when to buy"). I had an issue where my hard water was leaving sediment in my washing machine's solenoid causing it to stay in the open position. We came home to a door-open front-end machine almost ready to spill over. Now we have a sensor in the laundry room. We had high water pressure in our house which was causing our on-demand tankless heater pressure relief valve to started to let out a steady stream. We had a sensor there to cut off the water and save the day. I now have a pressure regulator (WATTS) and water e-treat (WATTS) system! Speaking of which, not that I don't trust my plumbing work - but the areas I was working with, I put a kids snow sled under my work when I was done to collect any water and put a sensor in it. No leaks BTW! Speaking of the sled to collect water - I use decorative square planters to put my bedroom and living room humidifiers in during the Winter with a water bud in each. Last winter, the side of one of the humidifiers broke and messed up my living room hardwood floors. I use a shoe/boot tray for the cat's water fountain and a sensor just in case they knock it over. I actually do the same with my hot-water tank too - ensures it will hit the senor and buys a few minutes between the valve shutting, water leaving the system (pipes above), and someone to get there. Last Thoughts I am excited to build on the YoLink system, I plan on picking up an alarm and some of their other unique products coming out - smoke alarm, CO2 alarm, outdoor alarm, outdoor motion sensor, outdoor contact sensor, etc. Pretty exciting stuff. BTW, I was not paid in any way for this review, and I am not new to the smart home space - I use everything in my house Tuya, ST, LIFX, Hue (which sucks - Paul Hibbert is correct on that) so I am not just blown away with the novelty of this, I think its a great brand that has a lot of potential with the LoRa. ... show more

  • Works well … when it works (Updated)
I have 12 sensors and have had the leak detection installed for almost 2 years. Inexpensive, easy to set up and generally works well but the exception is frustrating enough that I’m seeking alternatives. If the router or internet falters, the hub (hardwired Ethernet) and every sensor goes offline. No biggie on the hub. I have the same issue with Lutron Caseta on occasion. Unfortunately restarting the hub doesn’t fix the problem - I’m also forced to physically dig out 12 sensors, many in very hard to access locations, And hit the reset button and then it’s OK until the next time. Very frustrating way to spend an hour 3-5 times every year. Truly wish they had handled the restart / reconnection more elegantly. I’d still recommend for smaller deployments in easily accessed areas but for a larger house, consider some alternatives. Updated: I was contacted by someone from this manufacturer and they shared that I was one of the original purchasers (early adopter I guess) and that their updated hub eliminated the connection problems I reported. They offered to provide an updated version to me (which they did) and only asked that I provide an update based on my experience. The new hub went in easily and has been operating now for 45-60 days. So far, it's been exceptionally stable - no connection issues and when we had a power outage, the system came back up and all sensors re-registered without intervention. Raising to 4 stars and wanted to refine my review based on their updated hub and proactive outreach. ... show more
