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 like that I ocassionaly get loss of signal alarms as it usually means my router needs a reboot as other devices are down too.The audible alarm is loud enough but not overpowering

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!!

Used in the water leak subsystem of my home automation system. Tried several commercial water leak detection products but all came with a discrete sensor that only detects a leak if placed in a depression under the source. This sensor cord is so much better as it is 6 feet in length and can be connected in a chain of up to 3. It can detect water leaks along its whole length. Uses. Standard 3.5 mm connection. I have this connected via low voltage wiring to an ESP32 microcontroller that can handle 5 of these detector cords For most non-diy people, I would suggest replacing the discrete sensor that comes with most leak detection products with this cord sensor. Those discrete sensors are not very useful where you are not able to place them in sump directly under your washing machine for example. They are likely to miss small leaks but would work well if a pipe burst...
