The smart leak detector is a standalone sensor that can be placed anywhere in a home to alert you when and where it detects moisture to help prevent water damage and loss. If the smart leak detector senses the presence of water, extreme temperatures or high humidity, it will alert you in one or more ways, according to set preferences: Moen smart water app, text, phone call or email.; ; Brand Name: Moen Sub Brand: Flo by Moen Smart-Enabled: Yes Product Type: Water Leak Sensor CSA Listed: No Power Source: Battery Package Type: Boxed Height: 3.25 in.

Great Sensor and app but issues with Asus AI Mesh
Have 8 sensors at various locations in the house, unfortunately the sensor pairing with my new ASUS mesh system is a nightmare. Need to shutdown the mesh, configure the sensors and than restart again.If for any reason, the rourter restarts or the sensor battery dies…need to follow the process again!!.

Not worth it.
Difficult to pair with iphone/xfinity. Tech support gave setup info that was wrong!Then mice chewed through sensor and wire. They must be made with that cheap soy based plastic which rodents love. This meant that if I had a leak, it would not be detected!Support said that they don’t sell the part but they sent me “special coupons” only available to VIPs.The special discount coupons still had prices higher than Amazon prices.

Decent – updated
This alarm works perfectly at detecting water. A few caveats: As people mentioned, the pairing and Wi-Fi setup steps are missing from provided setup instructions, however, within minutes I located a short YouTube video that quickly filled in the blanks, and once you do this, it takes a few minutes to connect. Second caveat is that the provided alarm is very quiet. Your smartphone has louder ring options. So, you really need to rely upon the iPhone notification alerts to have a clue that it is going off, unless you are sleeping right next to your sump pump or wherever. I rigged mine to hang into a basement drain with the sensor on cord. Works.My sump failed, and I would never have known since I donât go into basement daily and check, and dehumidifier regularly drains to this pump. I got a notification on iPhone from the Flo app while away from home, and checked sump upon return to determine sump had failed, but water was still in drain, so no overflow. I caught it early enough to minimize cleanup. Itâs just a little, relatively cheap device, but it works.

Packaging and Performance to temp., moisture, and alarm volume
As other reviews state, the single unit I ordered arrived with the battery ajar and insulating strip off to the side so the battery had been draining since it was installed by the manufacturer. After setup, the Flo app indicated about 60% battery life remained. Will be good if Moen sends a new battery…time will tell.App installed on iPhone 13mini running iOS 16+. Many questions to answer to register but par for course these days. First try to connect to our home WiFi seemed to work (I had no prompt I entered my password incorrectly) but after finding the system not connected, I figured out the problem on second try. The app seems well designed. I set the acceptable operating range of humidity, and temperature I wanted and checked the boxes for email, text, and push alerts. After testing the hardware, I have yet to figure out how to delete the activity log, but the log can be filtered, collapsed and hidden. The alarm events can be deleted (just not the log).The primary sensor responded quickly to water. The main unit responds with beeping alarm for about 10 seconds and then stops and would not respond again if it remains sitting in water. If it dries, and is wetted again, a new alarm event occurs without manually resetting anything. The alarm beeping sound measured roughly 62dB at a distance of 5ft (1.5m). A nearby gas, forced-air furnace totally masked the sound of the alarming detector. Given the alarm shuts off after apprx 10 sec., one would need to be nearby, in the room to have a chance of seeing the LED or hear the alarm. (I believe most smoke alarms register around 95+dB for comparison). Don’t count on hearing this alarm over other household noise.Disappointingly, the primary alarm sensor toggles to the remote sensor when the remote sensor is plugged in. I was hoping to place the primary sensor on a floor drain covering and the remote sensor under the washing machine so if the drain from other sources backs up or the washing machine leaks, I would get an alert. You have a choice of one sensor or the other, but not both. The remote sensor responded quickly to water.To bluntly test for low temperature, I set the low end of the desired operating range to 40F (4.5C) and placed the unit outside where the winter temperature was 28F (-2C). The unit sensed the 40F (4.5C) lower limit in roughly 15 minutes and triggered the text and emails as expected. This 15 min delay was comparable to another remote sensor for a smart thermostat I also placed outside (indoor room temp. was approx 70F (21C). I did not examine how loud or if the alarm sound changes between the different sources of alarm (cold or moisture) but I did not hear the alarm inside when and if it was audible outside.I have no experience with other similar sensors on the market today so a comparison isn’t possible. I hopt these details can provide someone else useful information from which to make their own comparisons.I think for the price, and having experienced two human caused basement floods and one nature based flood during a deluge of rain, I’m satisfied with this purchase so far.Suggestions would be to allow for a volume adjustment of some sort (like toggle 62dB or 110dB) so the user doesn’t have to rely only on text and email alerts, don’t shut off one sensor when the other is active (better value for the $), add feature such as multiple emails to the app so that some users could receive alerts but not have access to the settings (i.e. for renters vs administrator, etc.)Hopefully my mostly positive impressions last as time goes on….speaking of which….how long does the battery last when it has 60% of life remaining….time will tell when the unit sends the 20% remaining battery warning I also triggered to ‘on’.

Got it working, but battery arrived dead and ios app installation and setup was troublesome
Main Issue: Both devices I bought died after one year of use!The package arrived and the battery was dead….the tape that was supposed to protect it had slipped off. This is apparently a well documented issue and I feel Moen should send me a replacement battery. Fortunately I had a spare battery from another device.I’m an electrical engineer who has worked in the IT business for the last 22 years, so I understand technology. I mention that only so you know that I have installed hundreds of software packages over the years and this installation was NOT seamless. I honestly still don’t know how I got it to install. Here are a few of the things I had to do.1. During account creation, I stumbled on clicking the Terms & Conditions checkbox first, before entering my name and phone number, otherwise the app would not let me click the checkbox and continue to the next page.2. During installation I was sent an email verification to my Yahoo account. I clicked the box in the email to verify my email address and went back to the app and tried to re-login, but it said it was an invalid account. Note that I was able to login via their website, so I know the account was valid. I stopped and restarted the ios app several times and it finally worked. Perhaps an account replication delay?3. During setup, the app told me that it was updating the firmware in my device and that it would take 20 seconds to complete. Several minutes later I deleted the app from my iPhone and reinstalled and it then allowed me to continue with the setup.It was a frustrating experience, but once the setup was complete I was pleasantly surprised by how well the device worked, at least during testing. I configured the app to send me texts when water is detected, and it worked flawlessly. The unit is now in my basement by my water softener.Unfortunately, both devices I bought died after one year of use.

Nice backup
Have a Moen water shut off but a leak before the shut off can still flood your basement as almost happened to me. Got this to detect such a leak. Cheap insurance!

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.

I purchased 4 of these devices:The first 2 paired without issue and appear to be working fine. The battery on the first one died within a few days, and the 2nd one lasted about 2 weeks before dying. These use CRA123 batteries which do not come cheap.I was never able to pair the 3rd one, no matter what I tried; it always failed once I connected to the wifi network. I tried adding the network manually, I tried resetting the router, I tried changing the AP name, I tried manually connecting to the network, every single attempt failed, and customer service is of absolutely no use.The 4th one paired, and despite having a brand new battery (not the one provided) it reported the battery at 43%. I took out the battery, and the app never informed me that the device was offline, I even waited 20 minutes to see, and still nothing, it was reporting the same 43% battery level and offline.Bottom line: I would not trust these things to alert me in case of a water leak. Given the cost of each device, I would have expected it work flawlessly, but I’ll be returning them and going with either Honeywell or pretty much any other brand.If your devices all appear to be working, I highly recommend doing a test to see if they are reporting correctly, dip the sensor in water, try taking out the battery, and see if the app reports it.

Doesnât work, I tried to returned but need to send to USA and costs a lot.Not compatible with app

No instructions re setting up in box. Finally got it working after search youtube. Stopped working when wifi ( as a result of nbn outage) and havenât been about to get it going since. Assuming battery supplied was depleted and canât make any further suggestions until I purchase a battery – not a common one you have around the house so buy a few for future replacement

The adhesive doesn’t last very long (separated from the unit base and dropped the whole unit into the sump pit, fortunately the pit was dry at the time), so use a screw. The “base” for this device has a very small hole for a screw, it may be hard to find one that small and long enough to mount onto drywall.The initial setup was somewhat tricky – it refused to pair after several attempts. I had to contact Moen support which was great. It appears that IOS utilizes a weird privacy network (mis)-feature which is entirely unnecessary on a private network, but will interfere with the moen device attempting to connect to the network during pairing. If I recall correctly, the (mis)-feature is called MAC anonymization, which is minimally of use ONLY when you’re roaming on public wifi. Which you really shouldn’t do anyway.
