Aqara T1 Smart Valve Controller

Some YouTube videos popped up today on this device. I don’t have power near my valve so this one interests me due to the battery power. The specs say matter compatible through Aqara bridge. Should I be able to get it into Hubitat through matter? I already have Zooz water sensors in Hubitat to automate a shut off with

Thank you.

Tagging along because it just popped up on my YouTube as well. I have two different valves on my incoming water supply, a Gate Valve and this which i believe is a Butterfly Valve:

The Dome shutoff valve that I got when living in previous house and all the other ones I could find only work on Ball valves. The Aqara says that it will work on a Butterfly Valve but none of the limited videos about it show how to install on Butterfly Valve or a picture of it installed on that type of valve.

I am also not clear if this will work on HE w/out the Aqara M3 hub. If not, even the cost of this valve controller plus the M3 hub is comparable to most other valve controllers.

Amazon should have it in my hands by EOD tomorrow. :crossed_fingers:

If this doesn't work, is anyone familiar with another valve controller that would work on a Gate Valve preferably or a Butterfly Valve?

Their Amazon post shows butterfly compatibility, so I'll be curious to see how that actually works -- I think that would be a first.

I admit my bigger concern would be the CPVC pipes and valve... CPVC is more brittle than other materials (copper, galvanized, PEX, brass/metal valves), so it's on the do not use or not recommended list for many automated valve manufacturers. I didn't see any CPVC-related info from Aqara in that Amazon post, but I admittedly didn't pour through it all in great detail.

I plan to build a makeshift frame around the valve controller to hold it in place so that it is not applying any dangerous stress to the pipe. Hopefully that will work.

In an industrial setting a gate valve is a multi turn valve where a disk (gate) is lowered into the path of the liquid.

I would expect most valves of the type you show in the photo are "ball" valves where a ball with a hole through it would be in line with the flow, when the hole matches up with the flow path, liquid can pass. When the ball is rotated 90° to the flow path the valve is closed.

In any case, the rotation is 90° so I would investigate any actuator that operates a "ball" valve.

The one in my photo is only a 90 degree turn and I am not saying that is a gate valve. The problem is all of the valve controllers I have found, like the Dome Controller I already own, only work on this type of ball valve with a long arm:

This is diagram from Aqara's website and it's not very clear but I think it is showing the type of valve in my original photo in post above.

This is that gate valve that is other option on my main incoming water line and it requires about 765 degrees of rotation.

I have found nothing that works on this type of valve. However, if there was something, I would prefer opening/closing this valve.

There is a good chance that Aqara T1 Smart Valve will work with the HE inbuilt drivers for the basic on/off operation - there is nothing specific or weird in the Z2M implementation for this device... :+1:

The copper valve you show is likely a gate valve. It looks like it is coming from the street. I know my valve from the street is a gate valve and looks similar. These valves are multi-turn and not suitable for automatic control.

It seems the problem you have is connecting an actuator to your plastic valve. Honestly I would be concerned using an automatic shutoff on a plastic valve. I have no direct experience, just my "feeling".

You could adapt the Dome you have by making a longer arm, however I feel you should find a location where you can install a brass ball valve for your dome. Or maybe you can find the fittings needed to convert your PVC to brass/copper, install a proper valve then convert back to PVC.

In my setup I exercise the valve once a month to insure the valve has not gotten stuck where it needs excessive force to move. It would be a shame if you had a system that didn't work when it was really needed.

I don't think that is going to work. The center of rotation of the Dome arm has to be over the center of rotation of valve.

Until seeing the Aqara today, the plan was DIY installing a compression-fit ball valve myself on brass pipe or paying a plumber big bucks. I already have the valve.

Thank you the response about getting this into Hubitat. I ordered one from Amazon and will update after I try to install it

I have one ordered as well. If you don't mind please update with the driver you used when you get it installed.

Amazon just notified me that mine isn't showing up until Friday; was supposed to be here today. :angry:

It will be a few days before I can get mine installed as I need to redo some plumbing due to a leak. I am interested in seeing how it works for you.

So I received my smart valve controller. I haven't gotten it installed on the water line itself yet but have assembled it to a shut off ball valve.

In this temporary setup it works great. I just hope it does the same when it has water pressure on it.

As for the integration I paired it to my Aqara M2 hub along with a water leak sensor to test it. It works well in the Aqara app.

Then I brought my M2 hub into Hubitat via Matter. When I did this it did bring the smart valve onto Hubitat as a basic switch and you have only on/off controls. However, of course it did allow me to integrate it into rules in Hubitat.

I will probably leave it this way until someone has had better luck getting it into Hubitat and someone writes a driver for it. Which I hope is soon.

If any of you gentlemen have any different experiences please share.

Mine arrived and, after getting out of the box and comparing it to my valve, I'm not confident it's going to work 100%. Plus @hydro311's comments about whether using the valve controller on PVC is a good idea has me worried. I am less worried about my skills as a plumber so I am moving forward installing a new compression ball valve on copper pipe and using my Dome Valve Controller instead.

I agree there is no way I would install it on a plastic PVC valve. I have a leak at my old shut off valve so I am having to replace it. I am replacing it with a brass shut off ball valve. Which is honestly what should have been installed in the first place. The Aqara valve is actually clamped directly to the brass ball valve. My local hardware store had one the valve would fit on.

Once clamped directly to the brass valve it works great sitting here in my house. Lol. The torque is all absorbed by the brass valve. Based on testing there won't be any transferred to the surrounding piping.

Now just to see if I am correct and will it still close the brass valve under water pressure.

I asked their tech support if it was safe for use on PVC piping and this was the response:

Hi,

Thanks for contacting.

The T1 has no material restrictions for the pipe; as long as the size and load capacity are suitable, it will work.

Sincerely,

I don't see anything unique about their device design that would alleviate my concerns about using it on PVC (it's design similar overall to other such devices), and no particular shade to Aqara support here, but I definitely do not trust they've actually tested this rigorously enough (or at all) to draw that conclusion.

There is no way I'd put this (or any other similar device) on PVC, but you do you... Hopefully you don't end up with stress-related pipe/joint/valve leaks.

ETA -- to be fair, their response is technically correct ... It will no doubt work on PVC, but the real questrion is for how long... The risk of stress-related PVC failure (sooner or later) is not worth it IMHO.

I would not want to clamp it to the PVC pipe. However, I am installing a brass shutoff ball valve in my PVC pipe replacing the plastic PVC valve that is there. I have mounted the Aqara valve directly to the brass shut off valve. I found one the spacing works. The brass shutoff valve takes all the torque and stress of the Aqara valve movement. You can hold it in your hand during operation and there is zero pressure against your hand. The valve and plumbing should last just fine like this.

I got my valve installed. Incoming line to shut off valve is 3/4" ABS plastic. I used a brass fitting and pipe clamps with the ABS plastic. The brass fitting of course screwed into the brass ball valve. Then coming off the brass ball valve is a 3/4" PVC coupler screwed into the ball valve and then glued onto 3/4" PVC. The Aqara T1 is clamped onto the brass ball valve. I have operated the valve several times and it opened and closed under pressure with zero issues. Also, where it is clamped onto the brass ball valve all the pressure is on the valve. When the Aqara T1 is operating the water line doesn't even visually shake.

The Aqara T1 appears early on to work very well.

There may be issues in the future with the plumbing but based off what I have seen to this point I don't suspect there will be issues caused by the Aqara T1.
