YoLinkX3 Version Smart Water Leak Protection Kit: X3 Valve Controller, Bulldog, (4) Leak Sensors & Hub

I started out looking for an inline system, but after extensive research selected this. We're lucky to have a well-functioning ball valve, so installation was easy (and I recommend the 10-year battery version for the controller). Our ball valve handle doesn't travel a full 90 degrees, so we did not set the pins to "hug" the handle, but instead set them to match the actual travel of the handle (I'll attach a picture showing this in the open position--notice the gap to the pin to the left so that the left pin pushes the handle less than 90 degrees to precisely this valve's closed position). Another factor is that the leak sensors are economical (about $15 each), so I felt ok buying a lot of them for all sorts of locations. It takes a bit of patience to fully understand the Yolink app, but once understood, it's really very good. And then there is the device-to-device (D2D) functionality that works even without house electrical power or internet. That permits placing the leak sensors just about anywhere in a big house. And no complaints about losing internet connectivity as I saw in the reviews of other systems. In short, really happy I went in this direction. And I expect to get an insurance discount.

Product works GREAT!! Had an issue with the function of the Bulldog & Controller at one point in time; however, Yolink's customer service was VERY proactive with phone & email support to help resolve the issue in a VERY timely manner! The two customer service reps Carlos & Joshua were very professional, patient & understanding through the whole process! They really went out their way to help solve my issue(s)! As a direct result, I HIGHLY recommend all Yolink products & their customer service!!

This product was successfully installed in under an hour. It's app is very intuitive and easy to use. The water valve shutoff motor was as advertised, and a simple 5 screw installation. It is powerful enough to handle my water valve lever, which is quite stiff. Note: The water sensors in this bundle do not have an oral alarm. I did purchase 4 additional next-gen sensors with the oral alarms installed. This was also in a bundle with an additional hub, which isn't needed, but the cost was less than purchasing the additional sensors individually. They paired easily with the first hub and all work as one system!

It just works as described. Many configuration options in the app. It works with the hub via Wi-Fi and w/o the hub via LoRa. Tested it several times with no issues. I even got a small leak under my kitchen sink and got the notification immediately. It shut the main valve off. Easy to install. Just line up valve's pivot point with the controller's pivot point.

I give the YoLink X3 Smart Water Leak Protection Kit 5+ stars. It is just what I was looking for and it worked perfectly.I bought and installed the YoLink X3 Smart Water Leak Protection Kit, it came with the Bulldog Valve Robot, the valve controller, four leak sensors, and the YoLink internet hub. I tried to install the Bulldog Valve Robot on a 1” PEX ball valve. The mounting bracket had to clamp directly on top of the PEX crimp ring. See first photo of PEX valve. This didn’t work very well. If I tightened the clamp tight enough so the Bulldog Valve Robot didn’t move during the valve close cycle the crimped PEX connection started leaking. I replaced the PEX ball valve with a Shark Bite ball valve. This new valve had a perfect place to mount and tighten the clamp ring. See other pictures of the final installation. The wire you see in the photos holds the Valve Robot in a side position. I did not have room to install the Valve Robot in the upright position as the valve handle would hit the PEX pipe when in the open position. I did have one problem. After I connected the leak sensors to the Valve Controller, so they would work without Wi-Fi and internet, two of the sensors would Open the valve instead of Closing it when the sensor saw water. I called the YoLink tech support. This was a great experience. The technician was very helpful and friendly. He said I needed to reconnect the sensors to the valve controller while the valve was in the closed position. He remotely reset the valve controller and I reconnected all my leak sensors. After I did this every thing worked perfectly. I give their tech support five stars. The manual shutoff valve you see in the fourth photo is the original PEX valve I reinstalled in the PEX line. You can’t have too many shutoff valves!

The motor was too weak to turn the valve, so what good is it? Do not buy this piece of junk
