Moen Flo Smart Water Leak Detector, White, 4-Pack 920-005 + 2-Pack 6-Foot Leak Sensing Cable

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 have been a big believer in the Moen product. The Moen Smart Water Monitor is solid. The little detectors are garbage. I have 20 of them running in our houses. When they arrive, the batteries in the units are rarely more than 50% powered. They die quick. They do not automatically reconnect to the internet and need to be manually reconnected. I also learned, after much trouble, that they DO NOT WORK WITH RECHARGEABLE BATTERIES. All the batteries in our home alarm system on every window will take a rechargeable battery, yet these little devices will not? Sadly, I am throwing all these things out, as I am spending to much time dealing with them. These units are in serious need for an entire redesign. I would happily pay more for them if they were reliable.

I have 9 of these. They work great and even send you an email if there is a Temperature, Humidity or water sensor out of range. My only complaint is that the battery does not last that long. I'm guessing every 6 months they need to be replaced and it is not a standard off the shelf battery however I think I pay around a dollar a piece for the battery.

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'.

Bought this after my basement flooded. Eventually I plan on getting the Moen flo smart water flow monitor which will pair wonderfully with this. I like how it shows temperature and humidity on the location where you set it up. Battery life is wonderful. App setup is a breeze and the app itself is nice. The ability for it to email, text, call and all the things is amazing. Its quite sensitive which is a good/bad thing. I have my water softener draining into my sump and it can splash at times and so i had to adjust my sensors location until it would quit getting splashed and going off.
