Quality to Price Value

If you’re going for a smart water detection sensor, you sometimes pay more for a lot of additional features or go for a simple device that will send alerts to a mobile device. The SmartThings Water Sensor is one of those simple devices. At $40, it’s one of the more affordable water detection systems.

That being said, it’s also restricted in terms of design and feature quality. Also, the overall cost of water detection can actually go up with the device, especially when you require more than a single sensor, which can end up costing a lot more than expected. However, the price becomes worth it with all the headaches and long-term costs you’ll potentially avoid with this device.


Occasionally, simplicity is good. The SmartThings Presence Sensor works well with its smart home system since every single component, including the motion sensors, locks, and lights, and works well while performing functions. That synchronization makes a widely successful system that manages difficult tasks.

In terms of simplicity, theSmartThings Water Sensor is a great device. It does whatever it’s meant to do, including alerting you through push notifications and via a SmartThings app in case of water detection.

Easy Installation

The SmartThings Water sensor needs a SmartThings hub which is more expensive. However, once you have that, setting up the sensor is pretty straightforward. Take off the back cover and peel off the plastic tab on the battery, which activates the pairing mode. After that, configure the SmartThings app to detect other devices, and the connectivity occurs automatically.

The default setting involves the sensor sending push notifications in case of water detection, but you may add in your own phone number to get text alerts. The SmartThings presence sensor is pretty compact because of its small battery power. This makes it convenient to place it in any small space or even under a potentially damaged or leaking pipe in the house.

That being said, the sensor doesn’t come with some extension cables for water detection in compact spaces. You will just need to stick the SmartThings Presence sensor near to the leak source as it can possibly go.

SmartThings Alarm System

Unlike other smart water sensors, the SmartThings alarm doesn’t come built in the sensor itself, or even in the actual SmartThings hub. This means you have to rely on alerts from a mobile device, and you can’t receive those in case of a power outage. The SmartThings Water Sensor also has little frills you get with other sensors, including things like temperature readings and external power support.

The provide CR2 alarm battery usually lasts around two to three years while being charged, which is ideal for smart sensors. In fact, the average battery life rounds up to about 17,520 hours. With the SmartThings app, people can let the sensor provide an alarm while connected to speakers, show a warning using the light bulbs, and even set off the shutoff of any water valve.

The SmartThings ecosystem can still give more, the system can also be configured with IFTTT so you can set up alerts via email, and connect with other products that SmartThings cannot usually support. The only issue is that, if you need some gadget to trigger the alarms, regulate large spaced or warn you about other potential issues, then the SmartThings alarm is too basic.

Many people think that the SmartThings alarm can trigger false alarms. You could get an SMS that the house is flooded, but go home and find no such issue. Conversely, there are moments where alerts don’t go through when there are actual leaks happening, which could be even worse.


The SmartThings Water Sensor has quite a popular fan base. With a variety of other smart home devices on the market, this sensor stands out. The primary reason is that the SmartThings Presence Sensor makes use of Samsung’s simplistic design. While some brands make sure to give a lot of advanced components and extra features, Samsung uses a different technique.

The company releases a large number of these SmartThings Water Sensors, and each of them is designed to be fully functional so that they only focus on one job. As you already know, the SmartThings Presence Sensor finds water leaks. Once the sensor is triggered, you receive a signal via the SmartThings hub and that’s it. A simple functionality!

There are about zero configurations needed with this sensor. All you’ll have to do is have the SmartThings hub and some other separate connecting devices to get full advantage of the sensor’s capabilities. On its own, the sensor has full functionality.

Water Detection

It’s crucial to differentiate a water leak sensor from typical flood sensors. These flood sensors are generally less expensive. By basic definition, it seems that they both do the same thing. However, you’ll spend a little more on the SmartThings Water Sensor for a valid reason. Flood sensors only activate once they have gotten physical exposed to water. With the sensor, you actually need an alteration in humidity.

Let’s suppose that you spill a little bit of water around the sensor. Even if you’re lucky and not even a drop landed on the actual sensor, the immediate change in the humidity can set off the alarm. That is important. If your sensor only activated in cases where it is doused or submerged in water, chances are you’d only be alerted above severe cases. This makes the sensor easier to trigger.

Water spills, splashes, and sprays are all equally capable of triggering the sensor to send a notification. A lot of people tend to find that this feature of the sensor to be slightly more sensitive than they’d like. You have a pretty good chance of dealing with a false alarm about once or twice with this sensor.

Even so, you’re better off being safe instead of regretting anything later, since they sensitivity shows that the sensor is good enough to find water leaks everywhere in a space once it’s been placed.


To figure out how the sensor can be integrated with a smart home, you need to look at a lot more than only the sensors own functionality. It is important to know the way it operates along with the whole SmartThings ecosystem. You have some systems being more advanced to provide wider control over every part of the operation, which can make the overall integration slightly harder.

Others systems are easier to use, although the user control options are a bit more limited. The Samsung SmartThings integration system combines both situations. While you get a few configuration options, the overall possibilities are restricted. This system makes the smartphone a central part of the integration. Regardless of the configuration, you will always receive a notification in case of leak detection.

Besides that, you are also able to configure the sensor for light and siren alarms. This is beneficial in case you find yourself facing drainage problems in your basement, or wish to keep an eye on a suspicious pump.

Smart Connectivity

Once configured with the hub, the SmartThings Presence sensor can be switched on and off using Alexa. Once the sensor sees moisture, it can work to switch off all other devices connected to the SmartThings Hub which is great since it will help you avoid power shortages with the other devices. The great thing about the SmartThings Water Sensor which actually makes it “smart” is the SmartThings alarm.

Instead of fretting over water leaks, the sensor will set off its light or siren with the first leak detected. Your phone receives an alert, so regardless of your own whereabouts; you will be alerted of the leak. And the SmartThings Presence Sensor offers an ideal mobile range that is enhanced using other products through the hub via a Z-Wave mesh network.

A greater benefit, along with the ability to detect moisture, is that the sensor also detects temperature changes. For all these unique features, the SmartThings Hub is essential. A hub is brilliant for smart connectivity since it is an integral port that connects every single smart device so that they can communicate with each other while providing Wi-Fi signals throughout the home.

Something to note is that not every smart device communicates using just one ‘language’. Smart hubs fix this by translating each product so that they communicate effectively. The sensor system also needs the SmartThings app that can only work on Windows 8.1, iOS 7.0 and Android 4.0 products.
