About this app

Phyn lets you speak the language of water.

From the free Phyn app you can understand how much water your family uses and where they are using it the most. Get alerted the minute a leak issue occurs and run diagnostic "Plumbing Checks" to proactively catch tiny leaks before they become big problems.



PHYN SMART WATER ASSISTANT

Leak alerts:
SMS and push notifications alert you at the first sign of a possible issue. Take action by connecting to a HomeAdvisor plumber in minutes through the app.

Plumbing Checks:
Turn off your water at the main and run Phyn’s Plumbing Check feature. In minutes Phyn will detect pinhole leaks and poor seals in your water system.

Water Use Plus:
Track and view your water use daily and monthly to get ahead of your water costs, and see how your home compares to others. Over time, Phyn learns your system and communicates your water usage down to each fixture. See every water event in your home so you can teach Phyn about your water use.

Pre-Freeze Warnings:
Phyn’s patented pressure sensing sees the ice crystals forming in your pipes before they have a chance to freeze and burst, giving you precious time to take action and avoid damage.

Smart Home Integrated: Use voice commands to learn about your water use. Phyn works seamlessly with Amazon Alexa and Google Assistant. And with IFTTT you can have Phyn trigger actions with other smart home devices.

Manage multiple properties
Monitor water use and receive leak alerts for up to 6 properties from one account in the Phyn app.



PHYN PLUS SMART WATER ASSISTANT + SHUTOFF

Auto and Remote Water Shutoff:
After Phyn learns about your home’s water use, it can turn your water off automatically to prevent damage from leaks. You also have the choice to turn your water off yourself via the app, from anywhere.

Leak alerts:
Phyn constantly monitors your home for leaks and potentially harmful changes in pressure and temperature. As soon as an issue is detected, Phyn sends you SMS and push notifications to tell you what is happening and gives you the power to turn your water off to mitigate water damage.

Water Use:
Stay ahead of your water bill. Graph views of your monthly, daily and even hourly water use.

Water Use Plus:
Track and view your water use daily and monthly and see how your home compares to others. Phyn learns about your plumbing system and communicates your water usage to each fixture type (showers, sinks, toilets, etc…). See every water event in your home so you can teach Phyn about your water use.

Plumbing Checks:
Phyn automatically runs daily diagnostic checks to give you and your plumber insights into your plumbing so that you can ensure that your system is watertight.

Smart Home Integrated:
Use voice commands to learn about your water use and control your shutoff valve. Phyn works seamlessly with Amazon Alexa and Google Assistant. And with IFTTT you can have Phyn trigger actions with other smart home devices.

Manage multiple properties:
Monitor water use and receive leak alerts for up to 6 properties from one account in the Phyn app.

The display looks nothing like the pictures posted for the app. The app is kind of a pain to read. A lot of the words do not display properly. Like next, is n..t. temp and humidity numbers only give you the first number. ie 7 instead of 75. Adjusted my display to the minimum and font. They still do not display. Hard to set up when you can't read the words and have to guess what they are. Bad display design. Only got it for insurance discount. Would return if I had to pay for it,

I have the phyn plus 2nd gen. It is excellent from a device standpoint. It detects leaks and shuts the water off as designed. The app is lackluster at best. It is glitchy and appears to be thrown together as an afterthought. There is no ability to view a graph of sensor trends. Moen provides the ability to see a graph that trends pressure, flow rate, and temperature. The graphs can be real time or over a period of 24 hours or 7 days. There is no reason phyn can't provide the same functionally.

The device is fine but the app has kind of a junky feel to it. Sometimes you're in the middle of a plumbing check but that app won't know it because it isn't properly synchronized to the device so it'll show the wrong info. It has this background with water flowing that shows whenever there is flow but that background is the same no matter how much flow. Rather than make the app look like a dashboard of information, they chose to make it like some chat and it's not better. But it works.
