Installation was very simple, and there is plenty of torque. The one thing that would make this product better would have been an option for external power adapter along with the batteries.

I was hesitant to buy this shut off valve because of several reviews suggesting it might not fit my pipe anatomy. But I recently had a $8000 repair bill for water damage in my home and I was desperate for a solution that would prevent another water disaster.The Aqara shut off valve arrived quickly. I was impressed with the build quality. Expecting disappointment, I immediately went to the main water shut off valve in my basement to check if the device would fit. I was overjoyed to see that it was going to be a perfect fit! It was a very easy install, taking no more than 15 minutes. Now the real test- would the thing actually work? I’m pleased to say that it worked perfectly, completely closing and then opening the valve. Then I tested automatic function by placing one of my Aqara water sensors in a dish of water. Almost instantaneously the device began closing the water valve. In less than 15 seconds my main water valve was completely closed. Time will tell about battery life. But for now I am very pleased.

I utilize a large array of Aqara sensors - approximately 20 spread between temperaperature sensors in every room, leak sensors on every faucet and appliance, etc. One of my long term home automation dreams was to leverage the dozen leak sensors I have around the house and automatically turn off the water if a leak was detected.For YEARS I have been awaiting someone reputable to come out with a valve such as this one. I saw Aqara had launched this, and smashed the buy button. Being a mechanical engineer, there are some things that I want to share with the Aqara community, and maybe influence Aqara to make some improvements. If your valve looks like my attached picture, be cautious about purchasing if you're not handy and willing to cobble a solution together.Pros:-Strong motor with impressive torque coming from 4x AA batteries.. If your valve is in good working order, this thing will most likely rotate it.-Compact design. This thing will fit almost anywhere and it keeps a relatively low height profile.-Super easy pairing, standard for Aqara. Aqara app --> Add device --> T1 valve. Done!-Manual hand bypass is well done. Just push down on the large grey tab and you have complete freedom to move the valve by hand. The valve then recognizes where it is after you move it.-Manual electronic actuation is simple. Single button push will electronically actuate.-My valve handle fit into the actuation arm like a glove, nice snug fit.Cons:-Not enough flexibility in mounting. I have a 1" standard Apollo valve on my incoming line to my house. This will be a common configuration, and I expect others will run into the same problems I have, which I will expand upon below.The mounting brackets don't have enough height to clear the valve stem (handle mount). I had to make a "custom" spacer out of some PVC pipe to push the actuator further from the pipe. If I hadn't, the valve was at an awkward angle which would have decreased it's effectiveness.The mounting brackets also fell DIRECTLY on the seam between the valve and the pipe. This area has a height difference due to the diameter of pipe vs. valve. This made it really hard to stabilize the valve. I tried swapping the handle of the valve 180 degrees (quick removal of valve stem nut), but that didn't change where the mounting bracket was located.Finally, one hose clamp is not enough to deal with the torque of this motor at maximum.The above items caused the valve to want to "twist" in a few different directions, ultimately meaning that there was enough slop in the assembly that it didn't fully close the valve when requested. To constrain it a little more I used some zip ties on the handle to lock it down a little further. This was surprisingly effective.My setup works, but I was pretty disappointed that I had to go through all of this to get it to "work". I am going to keep working to improve the install as I want it to be bulletproof so it works if/when it needs to.Aqara can improve this design by:-Allowing for a vertical adjustment on the bracket. (closer/further from pipe). A two piece bracket with a simple channel/keyway with a slot for the bolt will allow this.-Make the bracket extend further away from the valve, down the length of the pipe. This will allow it to clear larger valves and mount directly to the pipe, including pro-press valves which are bigger than mine.-Design the bracket to utilize two hose clamps. This will VASTLY increase at the rigidity of the mounting method and make sure that it doesn't twist on the pipe.-I would recommend changing the valve handle "gripper" to be a two piece clamshell design. Instead of two arms to cradle the handle, just use a flat plate with two screws that secure to another flat plate on the other side. This will accommodate different valve handle sizes and further constrain the valve to prevent "twisting" (like my zip ties did).

I replaced a competing product with this. It works well and exposes my valves to HomeKit. The mounting point would be my pain point for some users. You can get almost perfect results with some determination. I deducted 1 star because if someone has little plumbing experience it may not be as easy to understand how to help this succeed. Someone used to working on plumbing fixtures will be able to adjust as needed.I admit it took me a little longer to get this mounted than I expected. That was mainly due to the size of the valve I used and needing to adjust.Am I happy? Yes. I’ve bought two others. They automate opening and closing of water drains for my huskies. Will I buy again? Yes. I’ve got one more to install before summer. Bringing my total to four. Just take your time.Note: This is really strong. Don’t think you can hold it and test or not tighten it down to test. It needs to be firmly secured and you’ll notice a huge difference. Keep fingers away from the control arm area. It could be highly unforgiving if fingers were in the way. For that reason I would only recommended this for homes without small kids. If kids are in the home I would recommend one of the fully enclosed devices mounted directly to a ball valve. For that you’ll want to search elsewhere. That’s unless they have another product I’m not aware ofIf I could I would give it an additional half star for HomeKit alone. That was my selling point.

Love this thing, works good and comes as advertised. Paired with m2 hub and water leak detectors

I have aqara water sensors all over the house and needed this shut off valve.This way when a sensor detects water, this shuts off your water to the house, preventing major water damage.It's a little flimsy in the hook up, but works great.Highly recommended
