Terrible changes
This used to be a good system. They have changed the app so you can no longer correct the system when it misidentifies the water source (which is common). It no longer learns your patterns such as irrigation as well as before. When you set a manual override, you can no longer override the max time of 120 minutes. When trying to get support, you will be transferred online to their Moen web site. But, they no longer recognize your user name and password (probably lost it all during the transition). I would not purchase a Moen Flo again because of the horrible app and web control changes.

1 Star – Unreliable app and device
I am very disappointed with the Flo system. My leak detector was working previously and has never been damaged, but after it disconnected I have spent hours trying every possible troubleshooting step to reconnect it without success.
The app repeatedly gets stuck during the Wi-Fi setup process and provides little useful information about what is actually wrong. I have followed the instructions, verified my Wi-Fi network, restarted devices, and attempted the setup multiple times, but the leak detector still will not reconnect.
Even more concerning, the Flo Smart Water Shutoff itself does not function properly through the app. The shutoff control remains in a constant “connecting” state and never becomes fully available to turn the water on or off remotely. As shown in the app, the control continuously spins and never reaches a ready state.
A water protection system is supposed to provide confidence and reliability, especially when you are away from home. Instead, I have a leak detector that will not reconnect and a shutoff device that cannot be reliably controlled through the app.
For a premium product designed to prevent costly water damage, this experience is unacceptable. Moen needs to improve the reliability of both the hardware and the app, as well as provide better troubleshooting tools and customer support.

Unusable features need to be fixed
App has a warning and says my Flo device is offline, but the physical has all green lights on and the app is showing real time flow data. Tapping “bring back device online” does not work. Other buttons can’t be tapped in this version of the app either, rendering them useless: View support articles, contact us, view setup guide (all in the help center tab)

App is annoying. Many false micro leaks.
The system seems to register a lot of false micro leak alarms. From toilet useage in the middle of the night at odd hours. To running more than two things at once it tries to force shut off. My brother takes two hr long showers and it constantly shuts off on him. It does not like it when we run dish washer, shower and laundry all at the same time. I have other issues with this thing trying to say a massive leak when we were just running more than normal then it harasses to auto shut off water. It use to give a button to say “yes it’s me” but i can’t find it any more. I will retrain this thing again. We have rotating random schedules and it is in confusion a lot. Even with repetitive habits it should not be setting it off this much with micro leak detection. I thought it was to learn after a while what your normal is. I am going to retrain this thing. I don’t need to be alerted each time my room mate uses the bathroom at 2 in the morning.

Don’t waste your money
Completely useless, leak detectors do not function, the one device that connected to the wifi emptied a new battery in 12 hours. Expensive garbage
No bueno
After purchasing a new water heater and installing the Flo by Moen monitoring device; which was not cheap, it only lasted about a year before it was no longer able to track the water flow due to buildup on the impeller. After cleaning according to instructions from Moen, it still didn’t work, and you are unable to purchase a replacement impeller, the only option is to shell out more money for a new device. I think I’ll pass.

Hate this app and service
It will shut your water off anytime you use water outside your normal usage time. Shower late? Have guests over? Water will shut off. Then the login service fails on the app and you call customer service and they send you to voicemail because “they’re aware of the service issue.” Also, this is a scam with our insurance company because insurance MAKES you buy and install this device that hasn’t helped us once and does nothing but annoy us.

Decent.
Works well and as advertised. It’s nice to have constant monitoring especially when your other option is thousands of dollars of water damage. My only frustration issues are:
Some times it thinks an out of normal use is a water leak when it is not. These you just auto clear.
If you have higher than normal use it might auto shut off. Then you have to manually reset it.
Manual resetting with the tool is a pain but it’s rare you have to manually reset the device. Even then its just going out of your way to do it.
When you have issues you have to reset the whole learning phase so it can go through the process again.
When it detects a real leak you have to find it and it isn’t easy to find a pin hole leak. Randomly guess and hope you don’t have to wait for water damage to physically show.
Overall we installed this because we have pex piping and this is better than having thousands of dollars of water damage.

It doesn’t work
Help center doesn’t work. External links don’t do anything. Can’t pair one device to more than one app (2 or more people in a house? I guess that’s impossible). Validation issues. 004 error when pairing? 404 or 500 maybe.
Tech is obsolete
I can’t list all of the problems I have had. One thing it’s amazing about this product is when app goes down Flo is unable to help you. Your water supplies depending on Flo’s poor Tech technological setup.
Doesn’t Recognize PW
At first the app worked great. We were able to have it on multiple phones allowing for independent use. Now more often I get Error codes when putting in the correct information making it only useful for one. Not to mention it was stuck n away mode because we couldn’t get the app back to home mode and help is only available M-F, we finally had to remove the power and unlink the internet- then & only then did we have water.

Need email status updates
I downloaded 4.21.3 in order to resolve the server communication issues that crippled the app in February 2026. Moen simply must implement an email update. The app was unavailable for almost 3 days and we got no email notifications of this or how to resolve it. I only found out when I was called about a water problem at my house while I was traveling and I could not login to resolve it. Could’ve been a disaster. You simply must notify the customer of downtime and also what to do if there needs to be an update. Calling the help desk is not an option because they’re only open limited hours. So it was just dumb luck that I found out about the issue and how to resolve it, after waiting for 2 days.
Essentially every alert I get from Moen flo is a false alarm or a user error such as somebody spilling water on a leak sensor. So if the app is down and the water has been shut off, it’s a real problem to be halfway around the world and unable to login and resolve it.

Unable to login
I have 6 of these and are useless without the app
App stopped working
The stopped working. When do we move over to the new app?
When it suddenly stops working there are no support
App stopped logging in with infamous error 009 and I couldn’t turn my water on until I got to a laptop and accessed portal thru there
Unresponsive
This app has effectively died. It signed me out automatically, which meant I could not use the app to prevent a whole house water shutoff in subzero temperature. The app won’t let me sign back in - says my username/password are wrong and then, when trying to reset, that it can’t connect to the Moen server. I confirmed online that my username/password are correct, but the app still returns the error messages. Tried the new Moen water network app, but it likewise does not recognize my account.

Unreliable
Most of the links do not work. Leak detectors are unreliable; constantly disconnecting from a very strong and reliable network.
Login a Hassle
Hassle to have to login to the app every time. App does not seem to have an associated domain inline with Apple's guidelines for compatibility with Password AutoFill.
Terrible Product
The app itself is almost useless to navigation resetting passwords everything to do with the mobile experience on this app is a joke
Product Instability
Never Really Works. Always going online the offline. It displays errors when trying to view usage data. Moen support is not very helpful. Terrible design.
