I already had the wall plug powered version for main water supply valve in my house. Then I needed to control two valves outside where I have no power. The battery powered version was just as easy to install and connect to the app as the other one I have. If you need this type of thing I highly recommend YoLink.

Nice

Easy to install. Sensors have amazing range. Every home should have this.

I have installed the leak sensors under each sink, toilet, hot water heater relief, dishwasher, and washing machine. I know in seconds if there is a problem and where. I also have two of the smart switches, which i use to turn lights on and off in rooms even when we are gone.

We have Eero whole home WiFi and connecting the Ethernet model hub was a snap. Leak detectors connected via the app easily.

I have to say, I had my doubts when I ordered this (with hub). Searching the internet for a sensor without a corresponding security system attachment was daunting. I now have a fully functional garage open sensor to alert me if I left it open, that also can be linked into my Amazon Alexa system so I get verbal alerts as well as phone alerts. If you read the instructions, the installation and pairing is trouble free. I can also add additional sensors later, which will come in handy with a toddler granddaughter who shouldn’t be opening doors to certain areas of the house. I highly recommend this system.

Would like to see a 4, 6 or 8 pack too!

I ordered the valve controller 2 and evo valve operator plus leak sensors for all of the supply lines around the house. The valve operator installation was a bit tricky since mine was in a really tight space but still straight forward. With easier access to the main water shutoff it would have been a very quick process. The leak sensors were all easy to pair with the hub. I haven't checked yet if my insurance will give me a discount for adding this setup but either way it's worth it to me.

I am using the smart plug in conjunction with a leak detector and Home Assistant as an emergency shutoff for the pump that carries water from my distiller to my refrigerator. If a leak develops and he pump runs, it will pump the reservoir dry and keep running, sending water everywhere and burning the pump out. Now, if a leak is detected, the pump will shut off and I will receive an alarm notification. Peace of mind.

The system is very easy to use and setup.

We installed brackets where the only wall space available to hang a water sensor type 2 was in view. I placed the brackets (and the sensor type 2 cords) along our baseboards, and it looks "finished" and reasonably attractive. The water sensor type 2 fit nicely in the bracket, helping to get the "finished" look.

I have installed 10 of these around the house and the crawl space. I have not had a leak yet, but every time I have tested each cord attached to a water leak sensor 2 before placing it, it gave me a warning each time. Also, I like how the Yolink app gives us a picture showing the remaining battery life. Also, for areas where you want the sensor 2 above any water (they are not waterproof), the brackets Yolink sells, and the cords look good along the floorboards.

Hub setup and works like it should. The QR code had trouble with controller and had to get it replaced received new controller and scanned QR code and downloaded internet took less then 10 seconds everything works like it should

When moving away from wifi sensors I was worried the setup would be hard. YoLink made it so easy! Sensors are connected in seconds and reporting over long distances, through walls and fast!

I wanted to automate a few things in my home...but I took the risk and bought 10.
I'm so glad I did. It has caused me to re-think the level of 'smartness' for my home. These things are great...only take a few seconds to add to my YoLink ecosystem!
