Moen Flo Smart Water Leak Detector, Drip or Flood Sensor Alarm for Home, 1-Pack, White, 920-004

I just installed 12 units in my house. As a background, I had a different brand installed in my house and second home. All worked well. After a year or so, my wifi was upgraded at my house. Now I coukd not reconnect the units to the wifi in my house. But the units continued to work at my second home. So, after not having leak detectors for some time, the hose on our dishwasher broke and was flooding our kitchen. Luckily I was right there when it happened and shut the water down, which brings me back to how important leak detectors are. So after searching, I decided on the Moen. I easily installed all 12 Moen units. One did come with a dead battery. The issue I see that many have is that these units have to connect up to Wifi 2.4 and not your general 5.0 wifi. And some wifi appliancees out there are pretty ‘picky’ on which 2.4 works. That’s my experience. These Moen installed easily, as my 2.4 wifi worked well with them. My experience has been some brands will work with my wifi and others won’t. I’m lucky with the Moen.I also tested one by purposely putting a very slight film of water around a detector. And it worked flawlessly by sending an alert. I also liked the app very much. Gives you the temp and humidity. And you can set the type notifications and what info.So far I’m very pleased. Just be aware of those who had trouble connecting or staying connected. Comes down to the quality of their Wi-Fi. Like I said, some brands will work for you, and others won’t. I’m happy.

I love these devices but I hate the cost cutting of batteries only. In theory, you put these were water can leak but you would not notice in time. These would go under counters, in attics, in washrooms, and other areas that often are difficult to reach. I would pay double the price to have an AC adapter option. Exactly 1 year into my install the batteries are failing and the batteries are expensive and not environmentally friendly to dispose of batteries. The battery cost and hassle of replacing and buying batteries every year makes this product less than it could be. Ideally, it is better on AC. If you lose power, the device cannot talk to the wifi so the only reason for the batteries is bottom line cost and agency approvals. It was a marketing decision....not an engineering decision. I would buy another 3 pack and pay the additional cost of having the AC option.2/24I am done. I have come to hate the Moen design. The base unit does not sit flat in a cabinet and when you use the expensive cord it also does not sit flat. Where you put these devices is subject to disruption so the sensors are always getting moved which the design should expect but not with Moen. If you bump the cradle the connection to the sensor wire is lost and you will never know. The battery life is more like 8 months at most and I have had these long enough to prove it. The alarm volume is a joke. You cannot hear it 30 ft away unless the home is completely silent. How ridiculous to make an alarm and make it so quiet that if it is in a cabinet closed then no one will hear it beeping. I am moving to a D-Link that is a different setup and after Moen I can see why the D-Link makes sense and cents. It uses a hub that plugs into AC and has a "screaming" loud alarm. The Hub supports up to 24 sensors making the D-Link similar in price for the first 2 sensors but you saves hundreds of dollars if you need 6 or more. With the new system, you take a $25 sensor and place it on the floor of the cabinet, pan, or wet area floor. No mounting, no harness. The sensors link to the hub and that links to an app on your phone.

Excellent product even without the main shut off valve. I've had these for several months so far. They were very easy to install and easy to set up with wifi. They never seem to go offline either. I'm very impressed!! The sensors pick up even a drop of water. I had thrown a wet shower cap under my sink along with all my other toiletries and even the few drops that fell from the shower cap was detected. I got a alert on my app and an email alert. I'm definitely going to consider investing in the shut off valve.My only complaint is that the sticky pad that holds the sensor box on the wall is VERY WEAK! The stick doesn't hold up for more than an hour. Moen should consider correcting this. Otherwise, it's an excellent product! It still works well and does the job even when not stuck to the wall so it deserves 5 stars. You can't go wrong with this!

I just set up these Flo by Moen sensors. They appear to be working fine, but I was really unimpressed with the setup process that kept failing. Eventually it worked.Pros- Compact water leak sensor that can be placed directly on the surface, or connected to a remote sensor (included).- Audible alarm, not terribly loud, and alerts on my phone. But if set up properly you will be notified- Integrates with the Flo by Moen water shutoff valve to turn water off automaticallyCons- Installation/Configuration process is a little janky. You have to connect to a local device provided WiFi network to configure, but also need to have internet access. I had well over a dozen failures during configuring the three sensors I purchased. Just a little frustrating, and they should wait until after you connect the device to your WiFi network to update firmware as it would go much smoother.- Plan on replacing the batteries before you install them, mine were at 64%, 47% and too low to even connect to. Also, one unit had the battery contacts spread so wide that there was over 1/8" gap between the battery and the second contact. Easy fix, but that should not happen on a new device.- I would prefer that I did not have to use their cloud service to get these working, I would much prefer local connection so it would work fully if the internet was out. Just a personal preference.

I purchased this for my vacation home but it has 5g WiFi so wouldn't work. I have 2.4 at home and works well there. I had condensation build up under my water heater & got a notice on the app. Worked well.

When I first purchased this I was not impressed. The included cr123a batteries were all dead but Moen customer service was outstanding and replaced them. The metal battery contacts are flimsy and were loose causing the battery to lose contact but this was easily fixed by pinching them closer.These units connect via wifi on 2.4ghz only. If you are having issues connecting, press the small square reset button inside the unit and restart the process.I have one unit each in the laundry room and furnace room. I also have one dangling inside my sump pit basin a few inches above the float activation level of my primary pump to warn me of any pump issues. ( See picture)The last major thunderstorm activated the sump pit detector because the water rose dramatically in the sump pit. I got a push email, text message and robo phone call from Moen letting me know of a critical "leak" from my sump pit. I was then able to see with a camera above my sump pit in real time what was happening. This notification rich ecosystem is what makes these leak dectors outstanding. In the mobile app, you can customize how you want to be notified. Just make sure your modem/ router is on a UPS in case of a power failure to keep the wifi working.I will be purchasing more of these units in the future.

As an add on to the Flo sensor it works great going around the hole for our sump pump. Very sensitive so when testing just make a spot damp. It will keep going off until dry lol

I've been looking around for a battery operated water sensor, this one was a little on the pricey side. But the app was easy to use and setup. If you have a bandsteering unified wifi you might momentarily lose connection during setup if your phone is setup to use 5Gz, as this is a 2.4Ghz, the device will momentarily show disconnected during the setup phase, disconnect from your wifi and reconnect and you'll be fine, I had it up and running in 10 minutes. I dont know why people were complaining finding batteries for this, any of the big box stores have them. And if yours came with a dead battery return it for a new one.

After reading good reviews of this product ordered a box of three. The instructions, received upon arrival said "download associated app before unpacking" .Went to Google playstore. App "not available in your region". Huh? Tried using another device. Same. Went to company website. Very unhelpful, and trying to find email contact almost impossible. After 30 mins tracked one down. Fired off email. 24 hours later no reply. Resorted to social media. At last a response: "Android App only available in US and Canada". Well what a waste of time that was. Product therefore almost useless and returned. Luckily the seller was superb and understanding and refund easily obtained.So don't buy if you want the product to work with the android app!!

SE INSTALA FACILMENTE Y LA APP FUNCIONA DE LO MEJOR
