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.

Wow, these things are complete junk. About nine months ago, I bought eight of them to use on various faucets and other locations. Two were bad out of the box, and I never could get them to connect. I should have returned them but never bothered (for reasons that were entirely my own fault.)The app is required to connect them when first setting them up, but the UI for that is klunky. I set things up so that I would get both an alert on my phone and an email if there was a problem, and then I tested them by putting them in a bit of water. The alerts worked. So far, so good. The alarm noise was not very loud, but I was going to rely on the alerts on my phone and the emails.Then the "Device Offline" alerts started. Just one device every week or so. "On September 9 at 10:31 am, your Smart Leak Detector went offline. This could be due to a battery or internet outage." It would be offline for minutes or hours and then it would come back online. One alert for off, one alert for on.Gradually, over time, the alerts escalated. The day before yesterday, I got more than twenty alerts from all six remaining devices. Yesterday, I replaced all the batteries (not cheap), thinking fresh batteries would solve the problem.It didn't.And now, I will start researching other brands that will only send me an alert when there's actually a problem.

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.

I use these to detect if my dehumidifier bucket is full so I can go empty it in my shed. I've been using it for a little under a year, so here are my thoughts:- I really do wish there was a way to run these off of wall power. The battery lasts a long time when it's not beeping, but let's say I'm at work and it starts beeping, the battery will likely be dead by the time I get home. I solved this by getting rechargeable CR123A batteries, but I essentially have to have a rotating pack of them to replace in case it goes off.- After the detector puck has been submerged in water, it takes a while to dry out completely. That means you can remove it from water, dry it off, plug it back in, and the meter will still go off! It's annoying, but because I have several of these I can just keep a rotation of dry pucks as well.Otherwise it works well, and it does detect the presence of water. I've never had a Wifi signal problem with it, and it reconnects to the Wifi flawlessly every time I replace the battery.I had been looking for a water detector that had an external puck AND could be plugged in, but I settled for this one.I do plan on putting more of these around the house wherever water is.

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.

Purchased these in 2021, worked well for 4 years and now they are dying. Electronics just give up and don't power on anymore. They worked well during that time, but seems like things just don't last long anymore. Prior to finally dying, they eat batteries. Brand new, a battery would last a year, towards the end, about 3 months.
