Had a minor problem connecting the hub to my rental home router but that was fixed with a call to the internet provider who had to turn off the Terms of Service firewall. Worked slick as snot after that.

Right out of the box, they work every time!!

Installation is straightforward and operation is flawless once the bracket is properly aligned and secured. The Bulldog reliably operates the valve via the YoLink App, the set button on the controller, or D2D paired devices. I especially appreciate the addition of AC operation of the controller 2 with the battery serving as a backup power source. Having experienced significant water damage in the past from a leaking toilet I settled on the YoLink system 5 years ago and used it extensively in two homes. The Bulldog/Contoller 2 combination is a further refinement of the robot valve system that provides enhanced operability while maintaining existing valve hardware without any modifications for those who prefer that type of installation. I strongly recommend this system to anyone wanting a robust solution to automate closure of the main valve when integrated with YoLink leak sensors.

Yolink looked good when i was shopping, but i was pleasantly surprised when I installed it all. The hub setup was very straight-forward. Installing the remote sensors was just as simple. The mobile app is stable, intuitive and responsive. It all just worked.
Install the mobile app. Plug in the hub. Scan the QR codes to add the devices. Install the remote sensors and turn them on.
I was pleasantly surprised that the remote flood sensors also report the temperature from the location where installed. This is a great feature for my crawl space sensors since I live in a cold winter area. This can help warn me if my pipes are getting too cold.
I'm so happy with this system and it's pricing that I bought another kit for my daughter's family yesterday. Highly recommended!

works great Had issues with tying in 4 h20 sensors to close the h20 supply water valve and also turn-off the mini plug. Support team helped with this. If I get an h20 alert, the ys5003s shuts off main water valve and the mini plug which kills power to my induced blower on my h20 htr and shuts the water heater off.

I was very concerned that it would be difficult to set everything up. Turns out it was super easy. One smart valve, 13 sensors, and the hub. Everything works. I did have to ask AI to help me set up a weekly test of the valve, but everything else was pretty easy.

Only been a few days installed but everything is working well and meeting expectations. I was the test bunny, will be ordering more for our entire condo association.

Easy to set up. Works like it should. Takes the worry out of “Did I remember to close the garage door when I left?” And the YoLink finger makes it so I didn’t have to worry about hardwiring anything new. Very happy with the product.

Finding out when temps in freezer go up much more helpful than simply instantaneous temp

So far so good

Love this entire system. Easy install and great, intuitive interface

Works exactly as advertised.

Great valve, does what it should. Manual knob for open and close could really use an upgrade though. It’s flimsy and not fast. You need to turn it many times to get it closed.

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.
