Customer Ratings & Reviews

First, and foremost, I purchased this device to protect my home. Water leaks are costly and damaging, and I thought that a device like this would notify me of any leaks. Second, I live in California, where water is scarce and expensive. I was hoping that a device like this would allow me to understand my water usage better. I especially wanted to understand where I was wasting water so that I could conserve (and lower my bill). I have had this product for a month now, and here is what I have experienced so far: 1) It's a well-designed product and the packaging was very nice. 2) Installation was fairly straight-forward. It took about 1.5 hours. I had to use some plumbers tape to keep the connections from leaking. 3) The device regularly (i.e. twice a day) alerts me to "unusual low flows." At first, I was concerned about these, but now I just ignore them. Every leak alert has been a false positive thus far. 4) The device is supposed to determine which plumbing fixtures are using water (and how much). So far, it hasn't been able to properly classify any of this usage. Phyn says that this will get better over time as the system "learns." However, I haven't noticed any improvement in this feature yet. 5) The device is supposed to tell you how much water you are using on a daily basis. Based on my water meter reads, I used about 6000 gallons of water between Jan 10 and Jan 31. My Phyn says that I used ~2430 gallons. Once I turn my irrigation back on in the Spring, it will be interesting to see if Phyn can see any of my outdoor usage. So, in summary, Phyn has not been an effective leak detector or a water usage monitor. I just ignore all of its leak alerts and I can't trust its water usage measurements. I wouldn't recommend purchasing this product right now. Perhaps it will improve in the future.

The Phyn Smart Water Assistant is great in concept. The ability to monitor your water usage from within the house, seeing what devices are using the most water and possibly detecting leaks before they get too far out of hand. However, like many other new internet connected smart devices, it isn’t the most reliable at the start. Like when the voice assistants on your phone used to require you to say several sentences to learn your accent and still not get it right. Over time, with many more users and more usage, the smart voice assistants can now understand things that I can’t even make sense of. The problem is that we now expect smart products to just do what they are expected to do and not have to constantly check on it to train it. This is what the Phyn Smart Water Assistant may require you to do for a full year. Yes, it may be up to a year of confirming your water usage before this smart water assistant can accurately tell you your household water usage, especially if you don’t have a pressure release valve (PRV) installed on your waterline. The PRV is explained by them as “It’s like closing the door to a noisy street so you can hear the conversation inside” and this allows the Phyn to keep the noise of external water activity from being sensed in your lines. But, it doesn’t even accurately tell how much water has flowed through the very sink it is installed on. As far as installing, you have to download the app and follow the step by step directions. It requires it to first be plugged in, scan the QR code with the app and then connected to your 2.4 Ghz wireless network before installing. You need a sink with typical ⅜” angle pipes and a plug nearby. Out of the four sinks in my house, only one has a plug within 3ft of it, as the cord has to reach the plug, the hub and water sensors. The steps are fairly clear, but in one part it required some common sense to not follow the step literally as it missed out on connecting the hoses back to the sensors before turning the water on (See collage). Then you mount the main device in a specific direction with two screws or the included 3M sticky tab. It then asks if you have a PRV or if you don’t know will run a test, that it never completed no matter how many times I flushed a toilet. So, I just said I don’t have one and it proceeds to run the toilet flush test anyway, in which it passes and determined I don’t have one. As mentioned above, they highly recommend one and there is an orange bar that remains at the top of the app reminding you that you don’t have one installed. You can then run a plumbing check in which you have to turn off the main shutoff valve and you can see the psi drop instantly. This was a nice sign that the sensor does notice drastic changes in the line. It gives you a message like you are having a text message with the device and says it will give a notification when finished. Little did I realize when it said that, that I had to confirm it said that by selecting “Okay” and I waited 45 minutes for a notification that should have been 13 minutes. Now that it is installed, every time something is used, it is shown as an event through the activity monitor. However, I had to close out the app and open it again every time I wanted to see what the events were as the number increased, but not the actual detailed list. While looking at the list you get what it guesses the item used might be and an estimated galleon usage. This is where you have to help “teach” the assistant what was actually used. However, unless you are watching each water usage event, and pausing between uses, it is hard to determine. Especially when it has a usage range that can vary from a few tenths of a gallon to 15 gallons. Even more so if you go from flushing the toilet, straight to washing your hands before the toilet has stopped and the pressure fully returns to the lines. Overall, I do believe this has potential. It does need more users to help it “learn” what typical use and pressure changes cause. However, for the cost and expectation, this is not a product that you just hook up and it gives you useful information. This is not as smart as it needs to be for consumers at this price point.

I was very curious about what this product is all about and after getting it, while it’s great, I don’t see the purpose for the expensive price tag. From what I’ve seen on all the DIY videos, the purpose is to monitor your water supply, and apparently if you get the Plus version, it will automatically turn off in the event of a leaky water pipe or if water is left running —— but I have never once left water running so I don’t really see the huge relief it is providing. It is cool that it is compatible with Alexa and Google, but still, I haven’t once used it yet. You will need to download the Phyn app and connect it to your wifi (same as all the other house monitoring options out here) and of course this is where you get all your notifications that you're using more water than normal, or if there is a leaky pipe somewhere in your home. Here are some quick pros and cons for me: PROS easy installation; someone really broke down every step compatible with Alexa and Google Doesn’t take up much space at all CONS The cheaper version won’t auto shutoff your water in the event of an emergency a few connectivity issues at first as it utilizes transmitters All in all, if you are a high techie nerd like I am sometimes, this will be really cool, but I would not say it is an essential, life changer that everyone should have.

I have an issue with a faucet leak under the sink so I anticipated that with this smart water monitor I would be aware of any potential leak issue if occurs. Quality is super-premium and feels like the company paid attention to the installation to every single detail from mounting to installation. Installation is straightforward, The Pyhn app on smart device provides step by step instruction on how to install and the use of the necessary features from plumbing check to leak alerts and water usage data. I found it very helpful but my only concern is the accuracy of measuring and detecting leaks. I have noticed for two days I keep receiving high flow alert while my no water was used even with training the device by teaching it the type of use such as tub, faucet, spigot.etc.Not sure why it does that because this affects the reliability of the device or it is just a bug in the application. I will keep on eyes on it to determine how my home uses 189-253 gallons for 4 hours and water was not in use during that time. I wish it is just a software bug and not hardware reliability as detection is invalid. With that being said, 80% of the measuring is correct and accurate in terms of water run duration and estimate gallons.

Reason for grabbing this item is because we have a second house up near my little sister to visit while she's away at college because lodging is so expensive in the area. Unfortunately while we were away we had a leak and the water company called and said we had used $5000 dollars worth of water that month. Outrageous! Went up and installed Phyn with ease. I thought it was going to be a huge box that hooked onto the outside wall but to my surprise it was a small little box and a few connectors and we were up and running. The app is very useful and the format makes everything easy to find and read up on. I'm not sure how accurate it is as of yet because it's only been installed for a few days now and the information did say it's a learning process that you need to give constant feedback to it to make it more accurate. Have high hopes this will be our savior in case of any other costly leaks again beforehand this time! It is a little pricey for what comes in the box so hopefully it earns its keep Would highly recommend this to others

The Phyn wasn't too tricky to install - they physical install is pretty easy actually, if your have room under your sink to maneuver. Establishing the wifi connection though took a few tries. Sadly, I was unable to finish the installation wizard, the instructions had me repeatedly run 10 gallons of hot water down the drain as it detected its sensor. After, I'd guess 50 gallons, I gave up. Customer support is responsive - in fact they called ME while I was having issues with the app. Unfortunately it was while I was running a test so was completely inconvenient. After helping get out of the infinite look, reseting the app, and a number of other water tests customer support said this was a known issue with a few devices, and to return it to Best Buy and get another. I told them I would return it, but wasn't keen on going through the grueling install process again. The support agent suggested I buy Phyn's flagship product that installs at the main water line. He said the Smart Water Assistant just guesses, so will never be as good as their flagship. He made this product sound really sub-par. I returned it. I'll wait for more reviews and more competition in this space. Getting close, but we're not there yet...

The Phyn smart water assistant is a very interesting device and I don’t fully understand how it works, but from what the phyn videos that I watched basically say that your homes water pipes are a closed system and when water moves through it, it emits some ultrasonic waves that the Phyn smart water assistant picks up. Over time it can use these waves to determine where the water going to, for how long, and how much water. Say for example, you flush a toilet and that has a certain signature in your pipes. I am currently using version 6.3.0 of the PHYN app and I will speak to my experiences with that version. I do have some issues with it, and in full disclosure, I discovered that I do not have a Pressure Relief Valve installed so my reporting will take longer than the 3 weeks they say. The app makes the installation simple with an easy to follow step by step directions. You will need an unswitched power plug under the sink in which you install, and I had to add an adapter to mine since both of my plugs were being occupied by the dish washer and the garbage disposer. The two sensors were quite easy to install and I only needed a crescent wrench to install these. They fit inline with your water pipes and once you have them in, you just need to be sure they do not leak and the app will remind you to keep an eye out for that. Attaching the sensor to my home Wi-Fi was a breeze and the whole experience was just easy. After a short while the app will start alerting you to water events and will give you a time that the event happened, how long the event lasted for and an estimate for how much water was used and of course where the water was used at. These events seem to show up in the history after about 2 minutes or so and they are not very accurate for the most part (could be due to my lack of PRV). At first, I was getting very strange alerts, but over the course of a week, I would say that it has become more accurate. You do have the ability to “teach” the Phyn Smart water assistant by changing the alert to what you know it to be. For example, if you are running the washing machine and it registers at a toilet flush, then you can change it, and if Phyn gets something right, you can click on it and let Phyn know it got it right as well. I think the more you do that, the faster it will become more accurate. My biggest gripe with the app is when you are looking at your event list, there is no way to “refresh” it, say a swipe down on your screen. I have to exit out the app and go back into it for it to show new events. Hopefully, this will be addressed with an update to the app (v6.3.0). Another benefit of Phyn is that it will alert you to an unusual event, when my irrigation system first was detected, it alerted me via a text message and Push notification that something could be wrong. This is a nice feature to have just incase and it might save you some heartache from a major flood at your house. This unit cannot turn off the water, but it will alert you, Phyn makes a device that can turn off the water and I am very interested in that. Overall, this will give me some peace of mind and its fun to see how much water we use, and this might help us cut back on some usage.

It's difficult to give a good review. I don't know how accurate the results are, even after 4 months. "Some water was used by something at some time" is so far the accuracy. Had a leaky sink which was not detected. It was simple to set up and now have a general idea of water usage by day.

I was intrigued at the thought of being able to track water use, while also protecting against unexpected leaks. All of which could lead to large bills for use, or to fix any damage done by one. My current water provider sends email digests, and it’s going to be interesting to see how they compare. The unboxing experience was good, however the cardboard insert appears to release some dust, as it was on everything. Included in the box you’ll find the Phyn sensor, an all in one cable that includes the two water sensors, a USB A for power, and USB C for connection to the bottom of the Phyn device. The two water sensors can be used on either hot or cold connections, and the cable allows you to tear away to extend the cable length; same with the power cables. For the purpose of this install, you’ll need to make sure that you have access to hot/cold connections, and a power plug. In my case, I have a dishwasher occupying the plug, so I just connected a surge protector appropriate for under cabinet use. Prior to performing the water shut off, you walk through the app (which is free), and follow the prompts to power on, and connect the device to your WiFi. I can tell you there was some issues with the pairing process for me, and it required that I use the reset pin to restart the process. You will need to make sure that your mobile device with a camera to scan the QR code on the bottom of the Phyn. The account creation will require your name, mobile number (for the SMS notifications), and your physical address to determine usage in the area. Once I was able to successfully pair the device, it will walk you through some slides to begin the physical install of the device. Just make sure to have a large bowl or bucket to capture any water left in the lines. The installation process was fairly straightforward, with my only frustration needing to get around my garbage disposal, and the connections to my water filtration system. Having a wrench makes the install easy, and I didn’t need to apply any plumbers/teflon tape. Once the install is done, you’ll run the power cable to the inside of your cabinet, and affix it to the door. The instructions are actually really clear about these steps, and I had to flip the wall bracket side; which was incredibly easy. Power up took almost no time, but did require a firmware update, which for some reason ran twice, and was successful. The app then walks you through turning on your hot water, which takes a few minutes. This process is normal since the hot water generally does take a bit to come back through the pipes. Once it detects the water temp, it then has you flush a toilet to verify a pressure valve install. This process was also incredibly quick, finishing by the time the toilet bowl refilled with water. The app setup finishes after performing these tests, and when you enter the number of water items around your home (sinks, number of toilets, showers, tubs, etc.). After that’s it’s smooth sailing. You have to select between notifications going through a push, SMS, or both. The calendar view (water plus), gives you a drill down of the number of gallons, and any “events” during the course of the day. You’ll get notifications if your device goes offline for any reason, and when it wants to grab your attention to confirm the sudden use of water is normal. This happened when I turned on a shower upstairs. Over time, the device is supposed to become smarter, able to detect leaks, and anything it considers overuse of water. I’ll be interested to see how it matches up to my current water utilities drill down emails. So far, I haven’t had any major issues, no leaks, and it’s neat looking at the app to see your water pressure and the water temps. The app is incredibly easy to use, and if you do run into a pairing issue, a hardware reset is easily accomplished. For the price, ease of install, and the useful app, this seems like a good first try at getting smart about water use. Some of the notifications might be much, at first, but you’ll find them begin to decrease in frequency as it learns your usage habits.

Smart home monitoring is lacking a leader on water usage/leak detection, and Phyn is introducing hardware combined with technology to gain traction. However, this Smart Water Assistant alone is HIGHLY dependent on the user “Teaching” it, and it is somewhat time consuming. If you keep that in mind beforehand, and have the patience - you’ll see some of its potential here easily. Just FYI, we have a backflow preventer/PRV so we didn't have some issues some others mentioned. Install took about an hour, and I had to run an extension cable from the island cabinet as the outlet was not close enough under our sink. As far as getting up and running this reminds me of productivity tracking software I’ve administered in the workplace. The app itself is pretty well designed and intuitive. Once you have it mapped out to all the different water consuming connections - sinks (4) toilets (2) showers (2) dishwasher (1), etc - it becomes a bit easier, but you still have to keep an eye that nothing else is running, and sometimes the gallon consumption seems inaccurate. Waiting to see the water bill from the utility company and also very interested in the shutoff now that we have this. One thing that slightly irked me is if so smart in 2020 why no 5 Ghz? I actually had to enable 2.4 Ghz on my router so we could get connected.

I have the Phyn Plus and have been very happy with it. Thought I would install this device at a vacation home, sine easy to install myself. As other poster mentioned received many false alerts, inaccurate usage and found it frustrating compared to the Phyn plus. Good concept but not ready for prime time.

I've been trying to formulate an objective perspective on the Phyn because I wanted so badly to enjoy it's benefits for my home. We spend time between this home and another so being able to monitor the home's utilities is super beneficial when possible (smart anything). However, this Phyn Water System does not work. Some back story, my home was recently built, the water gets hot, and I have sufficient wi-fi to cover 5k square feet. It comes in this beautiful box with crashing waves printed on it. So you receive this luxe package, beautifully wrapped, minimal in waste and very detailed but short instructions. The application is needed to install the device, and the device itself looks like the fin off of a sea animal of some sort making it sleek and very appealing for under the sink. The bad... the device does not do what it's supposed to do and will not read any sort of water levels. Do the connectors work you wonder? Yes, the bolts fit my water connection perfectly and I did not need to alter anything. I had an outlet under the sink dedicated to the device. The set up process should be 3 simple steps. I started installation at 7pm one night and stopped at step 2 because it would not read anything and just gave me errors that the device could not get readings. I DO NOT know how much hot water I wasted that evening thinking it would work. Until the Phyn company can get this straightened out I can't in good conscience rave about this product for simply "looking" great and being a great "concept". It does not execute what it is supposed to do. Ultimately I have made drill holes under my sink, gone to the trouble of connecting the attachments to my water lines and now will now have irreversible things under my sink. I'm underwhelmed.

I was surprised at how well the Phyn Water Assistant works. At first, I was confused to how it would notify me. I got Phyn installed which took me about 45 minutes because of the way the plumbing underneath the kitchen sink. You have to place it in a place where there is an outlet. Nevertheless, I got it all connected under an hour. Also downloaded the Phyn app which now it’s monitoring water leaks. Installed both sensors on hot & cold water supply for kitchen sink. Again, it took at least 45 minutes overall. So far so good no leaks with the installation. Unit is working and will notify me if there’s any leaks around the house. This gadget will be very helpful in pinpointing water leaks, but it can get annoying as it notifies me WITH EVERY usage of water: toilet flushes, sink usage, etc.

Sometimes there is a lag. This is not good and also I had a drip and it did not show up. It’s a very well built device and easy to install

Trying to set this up is a nightmare. Everything is connected, water is flowing fine, no leaks, the hardware completes a firmware update, but it won't finish the setup process because it says it can't detect the water even though it is clearly flowing right though the sensors! One of the reviewers here is having the same problem and said that Phyn advised it is a known issue. I mentioned this to Phyn support who will neither confirm nor deny it, but nonetheless refuses to exchange the one I got for a working on that isn't part of the batch with a known issue. Very disappointing. I spent good money thinking I was going to have a smart water monitor and instead I am just plain aggravated. I would do yourself a favor and stay away from this product - at least until Phyn recalls the bad batch with the "known issue" and gets its act together.

I purchased this device after learning about it on This Old House (and after purchasing a similar device for my electrical box). I can say without a doubt this is the biggest waste of money I have ever made. The device just plain doesn't work and the support is abysmal. It would message me randomly during the day saying it "detected leaks" and that they had become "resolved". Watching my actual water meter showed that there was no water moving. I actually performed their suggested course of action in this case, replacing my PRV, which was another few hundred to a plumber. This did NOTHING to resolve the problem. When my house suffered a REAL LEAK this device didn't detect a thing. I've since tried 3 or 4 more times to reset it, move it, etc, and always have the same problem. Contacting support was very difficult and they suggested I spend even more to get their partner plumbing service out or "give it time to learn my system". A year later it still does the same. Save yourself the money and the headache.

Great concept but it didn't work for my house. It received tons of false alerts for 3 days. Lots of slow flow and high flow alerts that lasted for 12+ hours which overrided any other alerts that would have came through. Maybe the Phyn Plus would be better but the assistant wasn't worth the money.

Easy to install and connect to my wifi. Interesting to see how much water we are using in the house. Great customer support and product.

I don't know if this could completely replace the water leak sensors that I have placed around the house, but overall it tracks water usage and detects leaks and freeze. I've written up a blog here. https://mysmartesthouse.blogspot.com/2020/12/my-phyn-wholehouse-plumbing-monitoring.html

Very good overview of water usage throughout the entire house. Easy setup.
