A flood isn’t the only thing that causes water damage – those constant drips, trickles and puddles are often signs that damage is being done and disaster’s about to strike. This is why Eve Water Guard uses a sensing cable to monitor every critical nook and cranny of your home. You can also extend it to suit and lay it any which way you want.
So, if the worst happens and any part of the sensing cable gets wet, the siren on Eve Water Guard will go off, the accessory will flash red and, thanks to HomeKit’s special support for sensors, a notification will be displayed on your iPhone (if you’ve got a home hub). This makes Eve Water Guard an unparalleled water leak detector in terms of its full range of functions, wide-area monitoring and the reassuring feeling it offers.
Read on to learn more about what functions Eve Water Guard has and how you can use this accessory.

Siren, flashing light and text message alert
As soon as water penetrates the sensing cable’s braiding, the 100 dB siren on Eve Water Guard will sound and the LEDs on the rear of the accessory will flash red to serve as an additional visual alert. The red LEDs will continue to flash for as long as water is detected, but you can mute the siren via the Eve app – which is a breeze to do as the option pops up the moment you launch the app, provided of course a leak has been detected.
HomeKit or the home hub (HomePod, HomePod mini or Apple TV) will also provide a key additional alert in the form of a notification if the alarm gets triggered. This means you can have notifications sent to your iPhone so you’ll never have to be greeted by the worrying sight of water leaking everywhere should you be away from the source of the leak at the time or out of earshot of the siren.
All you have to do is make sure you’ve set up your HomeKit hardware correctly in the Home app: Go to the Home or Rooms view. Now use a 3D Touch or Haptic Touch gesture on the Eve Water Guard icon and then tap the gear icon in the detail view. Tap Status and Notifications, then activate Notifications on This iPhone.

Sensing cable, placement and testing
Thanks to electronic wizardry, Eve Water Guard knows the instant the sensing cable gets wet (for the techies out there: Eve Water Guard uses a resistive sensor whereby the ohmic resistance is changed if water penetrates the cable). Thanks to this principle, you can extend the sensing cable to an incredible 150 meters using the two-meter extension cables – enabling Eve Water Guard to monitor every nook and cranny of even the largest rooms or spaces, and not just the area directly beneath the wall outlet.
Hooking up the sensing cable to the base unit as well as connecting each section of cable couldn’t be easier either thanks to the 3.5 mm jack plug connectors, which ensure everything connects together securely and reliably for total peace of mind.
You can also lay the cable any which way you want: Lay it in a circle to monitor your washing machine, clothes dryer, pumps and other free-standing appliances; loop it under your sink; or run it along the wall parallel to your basement windows. Once you’ve laid the sensing cable and added Eve Water Guard to your HomeKit home, the next step is to test the alarm.

No bridge or starter set required.
Eve Water Guard works right out of the box, eliminating the need for additional accessories. You’ll need a home hub (HomePod, HomePod mini or Apple TV) to receive notifications and run automations.
Increase the reach of your devices
Add HomePod mini or the new Apple TV 4K to your home and your latest-generation Thread-enabled Eve Water Guard will be able to communicate via Thread – the mesh network that reaches even the farthest corners of your abode. This happens automatically without you needing to configure anything. Full Thread Devices (FTDs), such as Eve Water Guard or Eve Energy, can act as a router node and relay data packets from other Thread devices.
To view the structure of your Thread network and see where you can make improvements, simply go to the Settings area of the Eve app and tap Thread Network. Among other things, you’ll be able to tell which nodes your Thread devices use to communicate and whether you can further improve the stability and reach of your network and devices by adding one more FTD or moving one to a better location.

100% privacy
Eve accessories are designed to safeguard your personal data. All data is fully encrypted and only transferred directly between the Eve accessory and iPhone, iPad or home hub.

Five places where Eve Water Guard adds a watertight layer of protection
We’ve identified five potential problem areas where you should use Eve Water Guard to protect your home.
The home hub: An essential device for HomeKit-enabled accessories
Whether you connect to your HomeKit accessories via Wi-Fi, Bluetooth or Thread, your connected home is simply incomplete without a home hub – an Apple TV or HomePod. Your home hub gives you both secure access to your accessories while you’re on the go and enables you to set up automations.

Hello Albert!Notifications in HomeKit are only sent to the iOS device, that "owns" the accessory or is a guest to the owner. So yes, would be possible in theory but the security service would need an iOS device or a Mac.
And it may be a challenge to get them all connected.

Hello,Say I have a Home Hub.
1) Is it possible to use the Eve Water Guard as trigger directly from the Home Hub?
2) When using it as a trigger in an automation setup from the Eve app, will this automation appear and be editable within Home Hub?
3) Is it possible to get notified without setting off the alarm?

Hello Hymced!For receiving any notification while on the road a home hub is mandatory. We recommend using an Apple TV 4/4K or HomePod.
Automations are created in Home or Eve and then transferred and executed on the home hub. Detecting Leak from Eve Water Guard can be a trigger for like turning on lights, turning off power in a scene. Either create an automation/rule in Eve or in Home, please don't mix in one automation but you may use both apps.
You'll get notified (alarm) once a leak is detected. Please check more on:

You may turn off the alarm in the app Eve only, not in Home from Apple.

Thank you for the details. I have read the article you pointed out, but I want to clarify how "notification" and "alarm" works. You say: "You'll get notified (alarm) once a leak is detected". As I understand it, once the Eve Water Guard is activated / in detection mode, the 100 dB siren will trigger upon detection, and a *regular iOS* notification is send (which you call "alarm"). Am I getting that correctly? Do you have pictures to illustrate that please? Is this alarm notification setup automatically or one must create an automation whose action will be sending a notification upon detection? You also say: "Detecting Leak from Eve Water Guard can be a trigger for like turning on lights, turning off power in a scene". And what about sending a notification? Is it possible to automate the action "send a notification to someone" upon detection?There is a underlaying big question I am trying to solve. Here it goes: I live in a apartment, and I fear that if a 100 dB siren sounds, if, for some reason, I am not able to mute it via the Eve app rapidly, neighbors could easily after sometime call the firemen. And they could break down my expansive door just to shut it down... Whereas if I had been able to setup a notification without triggering the siren, I could have asked someone with my keys to check what's happening inside...

Hello Hymced!To get notifications you have to set this in the app Home from Apple and would need an Apple TV 4/4K or HomePod to receive it even when remote.
The 100 dB alarm on the accessory will start once a leak is detected, This can't be disabled. The notifications you get on the iOS accessory is a HomeKit based notification and this can be disabled.

Can you silent the alarm when you are not home? Also, can it just be a notification on your phone without an alarm as well, can the alarm on the device be turned off altogether?- Reply
Hello Dylan!No, the alarm can't be muted, not for Eve Smoke and not for Eve Water Guard. Best regards, volker

Thanks for reply! I was hoping it could serve double duties is all.- Reply
Sounds like a great device to add to my getting smarter home. I was curious if its also possible to use the water guard device as an action to a trigger in homekit, or eve? I dont have any sirens in my small space, and was wondering if the siren could be triggered if say a contact sensor was open, or door open.Thanks,
Jace

Hello Jace!I think you are mixing up some here. Eve Water Guard can act as a trigger. When water is detected the trigger fires and it could shut off a washing machine that is attached to an Eve Energy - this can be done.
What you want to do: Use a HomeKit enabled contact sensor as a trigger and Eve Water Guard in a scene to be executed.
This is not possible, sorry. Eve Water Guard alarm is for the accessory only.
