## Description

Protect your home from water damage with the Moen Flo 900-002 Smart Water Monitor & Automatic Shutoff. Designed for installation on a home's main water line, this smart device continuously monitors water flow, pressure, and temperature to help identify leaks before they become costly problems. When abnormal activity is detected, the system can send app alerts and automatically shut off water to help reduce potential damage. Powered by FloSense™ technology, the device learns your home's unique water usage patterns using machine learning. It can identify issues such as running water, small leaks, high pressure conditions, and other unusual activity while providing real-time monitoring through the Moen Smart Water App. Users can monitor, manage, and shut off water remotely from almost anywhere. Important Fit Information: This model is designed for 1-1/4-inch plumbing systems and is compatible with homes using main water lines 1-1/2 inches or smaller. The device measures approximately 7.7 inches long, 7.0 inches high, and 3.4 inches wide. Customers should verify available installation space and pipe size compatibility before purchase. The package includes the 1-1/4-inch Flo Shutoff unit, brass tailpieces, AC adapter with a 10-foot cable, spare O-rings, installation spacer, and installation hardware. Because the device installs directly on the home's main water supply line, professional installation is recommended.

## Questions & Answers

**Q: is there an API available to get data?**
A: There will likely never be a public API for these devices. Due to the fact the Moen has a subscription model in place for access to all functions. For them to release a public API would defeat their overall disappointing business model with this device. Great novel device, i love the idea, don't get me wrong, this whole subscription model is going to burn out consumers sooner rather than later With the moen ecosystem being locked down the way it is, future support for the device has me concerned. these types of valves are usually in a  house for 30 years before being replaced. I do not see Moen keeping digital support for a 300 - 500 dollars niche valve supported for that long.

**Q: If I was out of state from my home and a pipe bursts . This gadget will notify me and allow me to shut the mail line off if it’s connected to the main**
A: Hello,
In the event of a pipe burst while you are away, the Flo Smart Water Shut off will send you a notification and will close the water supply automatically. The Flo by Moen app offers selectable system modes for when you are  "Home" or "Away." 
Please contact us at support@meetflo.com if you have any questions. 
Thanks

**Q: Can more than one phone have the app and have the same control of one monitor>**
A: Yes, more than one smartphone can have access to the Flo by Moen app and its features. Thanks!

**Q: Why are separate detectors needed with flo?  I thought flo would detect a leak from the water main and shut off?**
A: It does; the extra sensors are optional and simply add an additional layer of detection. They also could detect a leak faster and shut off water immediately as they don't have to reply on an analysis of the overall water system; if it's wet, it's a leak and will tell flo to shut off water.
