D-Link  Wi-Fi water sensor and alarm

This water sensor may be used in any setting. It is compatible with Google Home and the Nest


  • If a water leak is detected, a 90dB siren will sound.
  • Inclusion in the Smart Home
  • Effortless installation; no need to worry about bursting water pipes.
  • The usual AA batteries

Being a victim of water damage to your home is no laughing matter.

One of the worst possible things that may happen is for your washing machine to accidentally detach from the water inlet pipe, causing your laundry area to flood.

All broken items must be replaced, and the area must be cleaned up as well.

Actually, who wouldn’t want that?

For a few reasons, the D-Link model is now the best bet for smart home water sensors.

  1. Lock down any potential problem areas in your house.
  2. One of the few smart water sensors compatible with Google Home and Nest, this one is a rarity.

No matter what kind of smart speaker or smart home hub you own from Google, you can use your Google Assistant to manage it.

Its tiny size makes it flexible in terms of placement.

It is a workable method that, with two standard batteries installed, can continue sending alerts for at least a year.

Besides being quite inexpensive (I think I paid around $69), I found that the sensor could be installed in such a way that it would be protected from water damage in the event of a flood.

The 7.5-foot wire allows for flexible placement, and notifications may be sent to your Google Home, Nest, or smartphone. (5-foot chord plus 1.5-foot water-sensing cable). How you would like it, really.

In the event that you own an iOS smartphone, you can use the D-Link smart devices app to manage it.


To integrate with your smart home, this sensor is ideal.

While conventional flood sensors serve just to alert you, IFTTT allows you to do much more with that information.

You can set up steps that will turn on other devices when a leak is found.

If you have a smart doorbell that doesn’t have a camera but still has a siren inside the house, for instance, you can set it to a different tone to alert you to a flood in the area of your bathroom.

And how it works?

  • Get it linked up to your wireless network first. There’s no requirement for a second hub or anything similar. Adding a new smart speaker is as easy as plugging it in.
  • Set it up in strategic locations such as behind the washer and dryer, beneath the sink, and other similar positions.
  • The time has come to begin leak monitoring. In the event that even a single drop of water is spilled while you are away from home, you will receive a push notice on your smartphone. If a flood is about to happen, you will be told right away so you can take precautions.

But once it detects water, the alarm goes off and stays off until you remove the sensor from the water, which is something I don’t like about this sensor, and it wasn’t easy to find.

Keep in mind that if you don’t act quickly, the alarm will drive you crazy.

And my main worry is this: what if something occurs when I’m not there? Assuming I am not present, what hope do I have of preventing this potential flood?

I’m not saying that it’s a great solution that can be implemented quickly and easily, but if you’re not at home and the flood alerts are driving you crazy, you have two more choices:

  1. If your water intake is leaking, call a neighbor and pray they are home.
  2. Get in the car and head home immediately to see what’s going on.
  3. My personal favorite is to install a water automation system that allows you to turn off the water with the push of a button.

Although there are some drawbacks, this sensor is a fantastic bargain. Click here if you’d like to see if it’s in stock and how much it costs at Amazon.

If you’re interested in learning about a better alternative than being warned that your house is going to collapse due to water flooding it, keep reading because I’ve discovered a cool smart home device!

Moen 900 Smart Water Shutoff

superior water detection sensor Invoking Google’s Smart Speaker, “Home,”

Also compatible with Google Home and Nest, but less well-known, is this water-level sensor.

More creative thinking is allowed here. Considering that it works with Alexa, Google, and IFTTT.

When you hear those three phrases, you know you can automate the task using practically any of the well-known smart home gadgets available today.

An advanced water turnoff, really.

So, it won’t merely alert you through your smart speaker or smartphone if water is detected; rather, you may turn off the water supply by saying “turn off the water” or “touch the phone” on your smart speaker.

We find this to be of great assistance. If your possible threat is found through a push message, you can turn off the water supply right away.

If you’re looking for an upgrade from the D-Link water sensor, look no further.

If there is a leak anywhere in your home, it will be found immediately.

To answer your question, how? The reason is that it monitors the flow rate of water through the pipe! plus It’s impossible to get water installed if you’re not there! Unless there’s a flood.

Second, if you have a smartphone or smart speaker, you can turn off the water using the Shutoff to neutralize any potential danger. D-Link will merely alert you, but you’ll need to investigate what the heck is going on.

It can tell if a pipe is broken or if there are other problems by watching the temperature, flow, and pressure.

Built-in Sensors

As far as flood prevention goes, this high-tech water valve is no laughing matter. It features three sensors that do things besides detect leaks:

  • the amount of water that flows through your main water line per minute
  • When the pipe bursts, the pressure will be too great to ignore.
  • The temperature will tell you if the pipes are obstructed.

As an engineer, I appreciate these sensors, but the extra math required to determine whether or not a pipe has ruptured is a royal pain in the a$$.

Thankfully, MOEN has built an algorithm into the Smart Water Shutoff to take care of this for you.

But it’s nice to know that real mechanical devices are keeping your Smart Home safe.

And how it works?

You can use this shutoff to keep track of how much water is entering your home after installing it at the water main.

With a detection rate of one drop of water per minute, it will alert you immediately on your phone if your water bill suddenly spikes or if an excessive amount of water suddenly starts flowing elsewhere.

To demonstrate some of the neat features of this shut off, we’ve provided a video demonstration below.

Useful tips about the installation

Concerning the setup, you’ll need to employ your handyman talents to join pipes together.

It’s true that some forethought is necessary before using many of the functions available.

Make sure the diameter of the pipe where you plan to install the water shutoff is the same as the diameter of the water shutoff before you go out and buy it.

Let me tell you some amazing engineering facts to help you understand why it’s so crucial that they have the same diameter:

  1. When fluid flows through a pipe of varying diameter, pressure, temperature, and other factors all contribute to an inaccurate reading on the sensor. You must not tamper with the sensor’s readings, lest you receive false information.
  2. Installing it is a pain in the neck because you need to track for additional couplings.
  3. By selecting a smaller diameter, you will shorten the service life of the shutoff. If the diameter of the fluid changes too quickly, turbulence will form, leading to an increase in temperature and the occurrence of cavitation. The simple version is that it will corrode your fancy smart water shutoff, but there are a lot of variables involved.

What you need to finish the process is a high-quality sealant and a reliable assistant to operate the necessary equipment.

Downsides of the Moen Smart Water Shutoff

This shutdown has problems, because nothing is ever perfect the way we imagine it should be.

  1. The subscription price is $5 USD per month. Even though the app has nearly every function a user might want, more advanced users will have to shell out some cash to unlock some of its more advanced functions. It’s not a lot, but it should still be gratis.
  2. A/N: The Preparation.If you’re a do-it-yourselfer like me, you shouldn’t have any trouble doing this, but for some people, it may be an area of expertise they lack; fortunately, a professional plumber can handle it.
  3. Even the most advanced smart home hub on the market is incompatible. Even if the sensor may be controlled from within the app, this poses a problem for home automation in the future.
  4. A weak Wi-Fi router will prevent the water sensor from communicating effectively. It’s a shame that you can’t use the smart water shutoff you just installed since your Wi-Fi signal is weak.
  5. Price

If you’ve read this far and still think the Smart Water Shutoff is the best option for you, you can see how much it costs and where to buy it on Amazon by clicking here.


Two fantastic water sensors that work with both Nest and Google Home are now at your disposal to keep your home safe from flooding.

One of the best things about having a smart speaker that is compatible with Google Assistant is how simple it is to use.

There aren’t many water sensors on the market that are compatible with Nest and Google Home, so it’s good to know which ones can provide the most reliable protection for your home.
