Eve Water Guard design

The Eve Water Guard is a small square box which features the Eve logo on the front. The rear panel of the device has a hidden light that will illuminate red if it detects water. On the bottom of the device you will find the sensor cable socket, reset button and HomeKit code.

As this HomeKit device is mains powered, you get a variety of different socket adapters that snap into place on the back of the Eve Water Guard. These will work for US, CA,  AU, EU, and UK regions.Eve Water guard adapters

On face value this is a great idea and will save Eve manufacturing costs as they can ship the devices internationally from the same inventory. However, the UK adapter appears to have a design miss, as when you snap it on and plug into the mains, the Eve Water Guard is upside down, as shown in the picture.Eve Water guard plugged in

To detect leaking water, the Eve Water Guard comes with a 2 meter sensor cable that plugs into a socket on the bottom of the device. On the end of the cable is a female aux port allowing the cable to be extended up to 150 meters. Eve has made this sensor cable of nylon outer layer with the electrical element inside.Eve water sensor cord

Because of the design, you could it can feed it around the walls of your kitchen to cover a greater area.

Eve Water guard install

Installing the Eve Water Guard is straightforward and involves very few steps. Your first step involves attaching the relevant adapter to the water guard and then plugging it into a socket.

Once the Water guard has got power, the device should flash. You then need to open up the Home app on your iOS device and add the accessory. You do this by scanning the HomeKit code and following the instructions.

The next step is to insert the sensor cable into the socket on the Eve Water Guard, and then you are ready to go.

Eve App, HomeKit and performance

As Eve has designed the Water Guard to serve one purpose, which is detecting leaking water, so you have limited options within the app. However, the information is clear and presented well.  If the “safe” status is shown, it means no water detected. The other status is “Alert” which means it has detected water.

You also get an option to check the log of the Eve Water Guard to look at past events. Which is useful if you want to look back, hopefully you will not be doing this often.eve app

In the settings menu of the device you can change the Siri name and alter notifications. You can also carry out a water leak test to see if everything works correctly. I did this when I first setup the device. You can also schedule reminders to give you a prompt to test the device. The water test is a fully guided process and completed in a matter of minutes.

HomeKit

As with other Eve products, the Eve Water Guard only works with Apple HomeKit. The Water Guard is shown as a water detector in the Home App and will push a notification if the device detects water. It also allows you to create scenes or automations that trigger if it detects water. If you running Apple TV or HomePod, you can also trigger them to play an alarm.

You can also ask Siri, “what is the status of the water sensor” and Siri will respond with the latest status.Eve Water guard HomeKit support

While all this will work fine locally in your Home, you will not not get remote access as it does not have a separate hub. However, you can solve this by using a HomePod, Apple TV or iPad running in your HomeKit setup.

Real world tests

While I was not willing to flood my house to test the water guard out, I simulated some tests in the kitchen. This test involved placing the sensor cable flat on my kitchen, drainer and simulating water leaking around its location.Eve Water guard test with water

Once the water came into contact with any portion of the sensor cable. The Eve Water Guard flashed red and activated 100DB siren. I also got instant alerts to my iPhone and Apple Watch via the Home app and Eve.Eve Water guard siren

When you open the Eve app, you would are prompted if you want to mute the siren which is useful given how loud the thing is. Once the cable has been removed from the water and wiped down, the status will change from “Alert” to “safe.”

Bluetooth range

Normally when people talk about Eve devices, Bluetooth and range often will come up. However, as with other Eve devices, I didn’t experience any dropouts or delays when using the Eve Water Guard. During my testing, I placed this in all corners of my home away from the HomePod and it performed well.

However, if you have issues, you may need to pick up an Eve Extend. Eve Extend is a Wi-Fi bridge for Bluetooth Eve accessories that an extra help with range.

Eve Water Guard Review summary

The Eve Water Guard enters a market that has several other options, like the Aqara Water leak sensor, that I reviewed. While we use both devices for the same purpose, they have a different approach to how they detect water.

However, the Eve water sensor offers a far more practical approach with its sensor cable feature. Plus, the fact you can extend the cable to 150m means you can use one device to cover an entire room. I also like the visual light along with the 100db siren to alert you to a leak, all built into the device.

While the options for the Eve app are simple, it does the job of presenting the information you need well. The addition of HomeKit and being able to include the device into automations and scenes.

The device has some downsides, first lack of hub for remote access. But I could see this as a plus in terms of no extra network devices. You can also overcome this if you have a HomeKit hub such as a HomePod or Apple TV. The 2nd is because it is mains powered, you need to have a socket nearby. But the upside to this is you need not swop the batteries out.

The only other complaint is the design oversight with the UK adapter and the water guard being positioned upside down because of it. This should not be a problem if it’s in a cupboard or behind a unit. But it might a problem for some if it is on show.
