Could be so much better

This app is really clunky. First it’s not at all clear that it is secure. It feels like the synchronization with the network leaves an unprotected entry point for hackers for each device. I feel like if it were secure, they’d make that clear. Second, the setup should allow you to set your parameters for all your leak detection devices at once-get all (in my case, 5) units in the app and named, then ask what parameters I want (humidity and temperature alarms), then apply them to all my units. Likewise, I shouldn’t have to add an address for each unit. It also appears that using a separate network connection seems to add a new home (if I try to use the existing address it says that address was already used) and it doesn’t ask if I want to use that existing address. Once you add a second address, there’s no way to delete it short of deleting the app (that I could find). Finally, if you set a parameter too low, or get a disconnected from the network notification, troubleshooting does nothing but bring you in circles.

Rubbish app

This app is terrible, and their “smart” devices are even worse. Constant network issues. Says the device is offline, then goes back online randomly. Changed my wifi network, and do you think it’s easy to pair the device to my new network? Of course not. I follow the instructions in the app, and it says “Pairing Error - No device found”. Don’t waste your money. I have no idea if the device is working or not, as it says it’s offline.

Crashes when setting up

This app is total garbage. It crashes all the time when trying to set up new devices.

Device

Need to be able to put on more than 1 persons device. Was away and my husband called and had rude customer services since change over. No water for one 2 hours. Live on horse farm need to fill water. Explained to repressive and was giving rude answers. “You have leak! “ my husband and daughter need capability to handle device as well.

doesn’t work well and not user-friendly

Sensors don’t do what the app says they are supposed to do i.e. pairing them does not work as it says it is supposed to work. If they go off-line, it is virtually impossible to re-pair them. App crashes all the time.

FAQ

What does the Phyn app do?

The Phyn app allows you to monitor your home's water usage, receive instant alerts for leaks, and run diagnostic checks on your plumbing system. It also provides pre-freeze warnings and integrates with smart home devices.

What are the key features of Phyn?

Key features include real-time SMS and push notifications for leak alerts, the ability to run diagnostic 'Plumbing Checks', detailed tracking of daily and monthly water usage, and pre-freeze warnings to prevent pipe bursts. The Phyn Plus version also offers auto and remote water shutoff capabilities.

Is Phyn free to use?

The Phyn app itself is free to download and use for monitoring water usage and receiving alerts. However, the functionality of the Phyn Smart Water Assistant and Phyn Plus hardware is required to utilize these features. The app supports managing up to 6 properties from a single account.

What devices is Phyn compatible with?

The Phyn app is designed to work with the Phyn Smart Water Assistant and Phyn Plus hardware. It also integrates seamlessly with smart home platforms like Amazon Alexa and Google Assistant, and supports IFTTT for triggering actions with other smart devices.

How does Phyn help prevent water damage?

Phyn helps prevent water damage by providing immediate leak alerts, allowing you to take quick action. The 'Plumbing Checks' feature can detect small leaks before they become major issues, and the pre-freeze warnings alert you to potential pipe bursts. The Phyn Plus model can even automatically shut off your water supply to mitigate damage.
