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've had a Moen Flo smart shutoff valve for about 4 years and overall pleased. We had to replace the internal impeller recently due to corrosion of the sensors (known issue - Moen is aware). During the repair of the impeller we decided to order the 3-pack Moen Leak Detectors from Amazon and found a Used-Like New deal that seemed reasonable. I let the box sit for a few weeks before opening and installing - big mistake! Read the many reviews about damaged boxes, dead batteries, loose or broken battery connection tabs, units disconnecting, etc.... I've had all of these problems. The product box was very banged up, the plastic battery tabs were removed on all 3 units and one of the batteries was completely DOA, all 3 units had damage to the metal tabs that make contact with the battery and hold it in place. Since it's beyond the return window, I was able to bend the battery tabs back into place on 2 of the units and get them to work, but the 3rd unit is completely useless. The pairing process is not difficult if you remember to use a dedicated 2.4G wifi SSID, and the Flo app is not terrible, but not great either. I've had both functioning units randomly disconnect from the network and I'm still troubleshooting. I've not tested them with a simulated leak event yet as I'm deciding whether the keep the 2 of 3 that are sort of working, or give up and kick myself for not opening the box before the return window closed.

These leak detectors are awesome! Our plumber highly recommended this system. But we did encounter frustration pairing the system to our network so that we could receive cell phone alerts when a problem was encountered. As a former head of quality I would fail the video provided by Moen. It is confusing and doesn't show all steps. Fortunately the Moen Flo technician we reached on the phone was awesome and got us on track.We have Android phones. The video instructions tell you to skip the pairing steps. We found out we had to go through them. You must use your wireless to link to the leak detection device (use the address provided): it will indicate that there is no Internet signal. Then click on "Retry" and your device will show that the firmware is being updated. Then you will be asked to link to your home wireless router and for a password. That should do it.Again, besides the frustration of pairing these are excellent devices that track leaks, temperature, humidity, and battery status. We are about to have installed a Flo device that can automatically shut off water to the house if a leak is detected from our installed devices or if it senses an anomaly. Having lived through issues with leaks, we are excited to have this system.
