I have this exact model for 4 months now, I also have several Govee leak detectors, the YoLink allows you to automatically shut off the water main if any of their leak detectors is triggered which is a big plus if a leak happens when you are not home, setting up the auto shut off required me to get help from YoLink customer service and they gave me the following instructions in case somebody needs it: Thank you for choosing Yolink for your smart home needs.

To set your sensors to trigger the valve to close, there are two ways on how you can set it up. Please choose one— either through alarm strategy (ideal if you have 2 or more leak sensors) or automation (ideal if you have 1 sensor).

>> To set it via an alarm strategy, carefully follow these steps:
a. From your main page, tap "smart" and create a scene. For its behavior, set the valve to close.
b. Go to your alarm strategies page and edit the alarm strategy of your sensors> tap "related devices" and make sure all your leak sensors (only) are included> go back once> tap "trigger action" and choose the scene you created> confirm> save

or

If you would like to set it via automation, carefully follow these steps:
>> From the app's main page, tap "smart"> automation> + sign> name your automation> when +> device actions> choose a leak sensor> water detected> behavior+> device actions> choose your valve> close > tap the 3 consecutive check marks to save your automation
**If you have multiple sensors and you would still want to set it via automation, you will have to create an automation for each sensor following the same steps.

You can also pair the sensors to the valve via D2D and this connection works even if the system is offline. To pair your sensor to your valve through the D2D control, please make sure the valve is in the closed position first then press and hold the sensor's SET button for 5 seconds until it starts flashing green then release the button. Press next the valve's SET button for 5 seconds as well until it also starts flashing green and release the button. The pairing is complete once the lights on both the sensor and the valve stop flashing.
**If you have multiple sensors, you will need to pair each sensor to the valve following the same procedure.

Second this, I originally got a mix because there were a couple places that I wanted to detect but not alarm (did not want farm animals to freak out when we were not at the barn).

After I got the ones with the audible alarm I opened one up and disconnected the alarm wire before I realized you can leave it connected and turn off the alarm/alert in the app. Definitely worth the extra $1-$2 for the alarm option.

get water leak sensor 4, model YS-7906
do not get water leak sensor 1, model YS-7903

Same thing with no screen temp sensor, definitely get the one with humidity for a bit more, you might want it some day. I have yolink temp/humidity sensors in 5 chicken coops
Both are IP65 rated
get YS8007 thermometer/hygrometer
do not get YS8017 thermometer only

I also recommend the speaker hub in addition to or instead of the standard hub, Standard hub does have ethernet option so there are tradeoffs on that choice

I have 26 yolink devices including one standard hub and two speaker hubs

I have this set up for many months now and really like it.
Have a friend who's a custom house builder and his plumber has this in his own house.

Things I like about it:

- If you have a 1/4 turn whole house water shutoff valve you can install this yourself without needing a plumber.

- Actually shuts the water off and doesn't just give you an alarm. The "just alarm" types don't truly help if you're not home, etc. Imagine a washing machine hose going when you're not home. It's like opening a garden hose full force inside your home. If you're at work and get an alarm or notification, a TON of damage can occur in a short amount of time.

- Can be set up to work WITHOUT power or internet. These have batteries and will still work and shut off the water even if there's no power. If a storm comes through and you lose electricity…you're still covered. There's YouTube videos on setting these up.

- Can be set up with a LOUD alarm ( another maybe $30) that will go off if any of the sensors are triggered. So, if it happens in the middle of the night you'd still know that it happened. If you have an oil burner and baseboard heating it can be dangerous to have the house water shut off. if the system has a small unknown leak, when the water is shut off, enough water can leave the heating system and cause a boiler explosion. I personally want to know when the water gets shut off even if I'm sleeping.

Quote from bluekiwi :
Unless installing this yourself a plumber may charge $500+. Also this is a more permanent installation vs other leak detectors due to the pipe connections (other detectors have threaded connections). Also you will want someplace to attach the motor portion since it does have a bit of weight to it and you do not want the strain on the pipes.
Permanent due to pipe collections? From what I see in photos it slips over and clamps to your existing 1/4 valve. No pipe work or plumber necessary. Other inline valves require splicing into piping, this does not appear to be one of those.

Not exactly sure what you mean. These can be set up to work when there is no electricity which means no internet or cloud. There's direct communication between the sensors and the shutoff. Believe you do need the internet on initial install though.

I integrate my yo-link sensors with home assistant. Have found the battery more reliable then the zwave sensors that i had. Also, I'd suggest grabbing the sensors with sound alarm when it detects water so the family can triage immediatly.

I went with YoLink with it's LoRa tech. Off-grid hubs can also send packets to the yolink server. yolink hub that picks up a yolink device packet will forward it, this allows you to get alerts when your hub is offline and there is another hub online nearby.
May I ask, how do you integrate the LoRa tech that the Yolink uses with Home Assistant? I have the HA Green with Zigbee and Z-wave and would love to integrate my Yolink system.

Quote from Johnny99x :
Might any of you fine SD people be able to comment on the Yolink products versus Govee, specifically for leak protection?
I have both. Invested in Govee sensors first several years back and even convinced my neighbor to get into them. Saved his basement 3x due to unforeseen leaks during the night, so they definitely work and I recommend them. Battery life is great and they usually give off an odd chirp when battery is running low, although I recently ran into one that had low battery but wasn't functioning when it made contact with water and wasn't notifying me of low battery so I still need to look into that particular sensor.
I just recently invested in YoLink because I found myself in need of a main smart shut-off valve, so I grabbed this exact one plus a few sensors. I used the IFTTT app to integrate both brands, so now if either YoLink sensors or Govee sensors get triggered in the house, my main shut-off valve will activate. You can't go wrong with either brand, but if you plan on doing a main shut off valve feature, go with YoLink. Check out your home insurance as well, some (not all) will give you a discount or a credit for getting this installed in the house.

Yolink saved my ass so many times, my combi boiler leaked once, first stair washlet pipe leaked once, whole hosue water filter housing minor leak once, the sewer clogged once and water shooting out from basement sink and washmachine pipe connector. Yolink leak sensor detected it and my yolink water shutoff thing auto shutoff the whole house water inlet so I don't need to deal with flood, those sensors/devices works great and doesn't get disconnected from hub at all!!!! I have no idea about Govee..... sorry.

I could see that working too.

Though at that point we should really talk about how fast DHL is.

I have been using YoLink for a few years and love them. Generally, they just work and work with a long range.

I just installed a new HPWH a week ago, and immediately disconnected the shut off valve. It has probably dried out from the install by now, but I really don't need one there. It's 6 inches from a floor drain.

I was going to get the speaker hub to add it but was really bummed it had no Ethernet port! What are they thinking? Maybe they want to be more like Apple.
