Quality, long range. Peace of mind
Update: This device has saved me from a large water bill twice. One time, I didn't turn the spigot tight enough, and I was informed via the app that 0.7 gallons of water has been running every minute for the last two hours. Last month, I was 2000 miles away from home, and I was notified that "water has been running for 2 hours averaging 2.04 gallons every minute." Turned out, my drip irrigation system was low on battery and couldn't shut off the water. ***** There's a peace is mind from installing this device. I no longer have to worry about water leaks, especially hidden slow drip water leaks that will go on for months. The monitor is surprisingly accurate and will reveal some interesting data like who hasn't showered in days and that my household uses the most water by flushing the toilet. I guess we'll need to work on that somehow. This one doesn't shut off water but that means it's much easier to install. And really an alert on your phone is good enough. Then you can shut off your water at the main or have your neighbor shut it for you. This device has a long range. My house is 300 feet from my water meter, and haven't had any connection issue.

Amazing option
I have a slab leak. While rerouting the pipes I'm looking for a water usage monitor and remote shut-off valve. I have doubts about a battery-driven monitor without plumbing. But it ends up being my best option. First, if I can't monitor the main meter, I have to buy 3 monitors, one for the house and 2 for irrigation. I can change that but it requires a lot of work - digging. My meter is underground on the public sidewalk. It looks dark and small in there and I didn't think the Flume will fit inside. But if somebody can plumb something in there, there must be plenty of space for the Flume. The other thing is meter compatibility. I have a Neptune without clear markings so it may be the one that is not compatible. But I think as long as you don't have a too new one, it should be compatible. The installation is easy. You just need to tie the Flume on the side of the meter with a thick rubber band. I had two potential problems. When the app tries to connect with my wifi, an error shows up telling me to retry. It doesn't surprise me as my wifi 6 has the same SSID for both 2.5 and 5 GHz. I might have tapped retry and they the app jumps to calibration without confirming that my wifi is connected. I tried to confirm before putting my Flume down the rabbit hole. There's no way to go back on the app. There's no wifi indicator. I tried to add a new device but it wasn't allowed because all the devices have a serial number. So I just put the Flume next to the meter and it worked. The 2nd potential problem is that the app tells me that the Flume moved more than once. It hasn't. I could have calibrated the app with the readings on the meter. But I'm impressed enough. I think the Flume is detecting the rotation of the red dial, which is exactly what the meter does to measure water flow. If a metal or a magnet rotates, it will disrupt the electromagnetic field around it. So without calibrating, I believe the Flume will be accurate, maybe occasionally missed a turn. First, it's reassuring that my slab leak isn't deteriorating into a measurable amount on the meter. When the app says zero, the red dial doesn't move and I don't have to pay for the leak. I reseeded the lawn and I was using a lot of water since to let the grass grow. But the Flume tells me I'm using over 300 gal of water a day when the sprinklers are on. I checked and all leaks are very minor. I have the incentive to change the watering program. And recently I removed the flow limiter on my showers. The app tells me that it's about a quarter for a long shower. The usage report is on every hour. So you can know how much water you use for the washing machine, dishwasher, and maybe flushing if you plan enough. Now for the remote shut-off, instead of an expensive valve, I found a mechanical "hand" to turn off the quarter valve for about $40. I tried and it should work. But it doesn't fit my very old valve because it is very bulky - the valve body is much thicker than the pipe. Any newer valves will fit.

Updated: lower stars due to greedy battery redesign
Update 6/19/23: I have had my flume 2 for two years now. Works great- but lowering stars due to flume’s changing the replacement battery to “proprietary”. My original pack that came with the unit lasted two years. The original pack is simply a holder for 4 AA lithium cells you can get anywhere. But Flume now wants you to buy a replacement pack for $14. It uses four AA cheap no-name Chinese cells spot welded in a plastic housing. Field reports indicate these cells last far less than the factory Everready cells that came in my original Flume2. So they sell you cheap, no name cells that last far less. Very disappointed Flume tried to change the battery type to proprietary, when we all know it is 4 AA lithium in the package. The approach is greedy and NOT environmentally friendly. The four “blue” spot welded AA are cheap, and don’t last as long. So, Flume added cost and materials (spot welding, molded case), all adds energy, not readily recyclable, and takes far more energy to manufacture and ship than the user replaceable original. Fortunately, I have the original reusable cage and will forevermore replace my own. Shame, Flume. Shame. Pros: Easy install, very good and responsive customer support. Cons: battery- see above. Missing a signal strength indicator on the app; I had a unit that could not connect reliably at 60 feet line of site- Customer support can see the signal strength, I could not- so no ability to self-diagnose. First, I LOVE the FLUME 2, when it worked. The first unit I received worked for 12 hrs- I enjoyed seeing the water usage patterns- but then it just stopped working- it lost connection between the Bridge and the sensor at my meter. The only way to regain connection was to remove the sensor from my meter and bring it close to the bridge. I spent days on the app chatting with Customer support, trying different things. In the end, they said: Just return it, it won't work in your application. I said "but wait, surely it should have more than 60 feet range?, maybe mine is defective". Eventually I had to "escalate" (to a manager), who authorized a no question asked shipment of a new unit. I installed it, verified it worked great- my meter is in a "vault" with a cement cover. I ended up being able to put the bridge about 100ft away, near a window but not facing the window. So the first unit WAS defective (low range). With the 2nd unit, I have now had great water monitoring experience. And, the customer support (via app chat) WAS very responsive. I dock one star for: a) no signal strength meter on the app? That was the problem- a simple set of bars would tell you if your bridge and sensor have enough strength. b) I had to convince them something must be wrong with the first unit, and ask for a supervisor/manager to intercede. c) there should be more troubleshooting/diagnostic tests and tools for self-diagnosis, without having long chat sessions with Support. FLUME customer support did the right thing, we figured out together that Flume 2 could work in my setup. High marks for the overall experience- they brought a 1 star (when they said "just send it back") to 4 star because of Customer support- they were always patient and polite...

Must for every home
It is easy to install and it works extremely well. I have been battling multiple underground leaks for months. I had to continually shut off inside house valve and watch water meter for leaks. Once I installed the flume meter it gives daily, by hour and by minute consumption. Plus I immediately got notified of leak and was able to take promot action. I would strongly recommend this product to any one battling any water leaks inside or outside home.

No Fuss Leak Alerts and Water Tracking with Flume 2
I purchased the Flume 2 a few months after buying my first home. I researched various leak detection options like Moen Flo and Phyn Plus but ultimately decided on Flume because it monitors water usage directly from the water meter. This means I can monitor leaks not only inside my home but also on the water line servicing my home and my sprinkler system, providing a more comprehensive view of my water usage and potential issues. **Installation & Setup:** No plumbing or wiring required—just strap the sensor onto your water meter, plug in the Wi-Fi bridge inside your home, and follow the app’s step-by-step instructions. The app even prompted me to take a photo of my meter for calibration, and Flume’s support team confirmed compatibility before I bought it. The installation took about 15 minutes. **Performance & Accuracy:** While I didn’t test it for 0.01 gallon per minute accuracy, I did test the Flume 2 by filling a bucket and comparing the readings, and they matched exactly. The app dashboard is intuitive, showing real-time and historical usage, and you can set up custom alerts and water budgets to help manage your consumption. **Leak Detection:** Last year, Flume alerted me to a leak. After checking inside my home and ruling out any internal leaks, I discovered that the issue was actually a small leak right at the water meter. I contacted the utility company, and they promptly fixed the leak. This year, Flume alerted me again to a leak. After ruling out leaks inside the house and at the meter, I hired a leak detection company who found the leak on a coupling on the main water line. These two leaks just show how correct in my decision on flume versus the other water leak detection systems. **Smart Home Integration:** I was able to integrate Flume 2 with both Hubitat and Home Assistant, which made it easy to incorporate water usage data and leak alerts into my broader smart home automations. This flexibility was a huge plus, allowing me to set up custom rules and notifications that fit my household’s needs. **Battery Life & Maintenance:** The battery lasted a little over a year for me, even with the sensor about 30 feet away from the home base, which I have set up on the second floor. While replacing the flume 2 battery was straightforward and only took a few minutes, it is a propriety battery pack though compared to flume 1. Flume also sells a replacement battery kit for around $20, which includes not only the batteries but also desiccant packs to help keep the sensor dry. The black battery pack does allow you to diy a battery pack if you like with regular lithium AA batteries. **Limitations:** Flume 2 won’t automatically shut off your water if a leak is detected, however, I addressed the shutoff limitation by adding a Bulldog valve robot, which does integrate with Flume and allows for automated water shutoff. While Flume does attempt to break down water usage by fixture type using machine learning—and you can help the algorithm by tagging usage events—I’ve found that this feature isn’t very accurate. One significant limitation I’ve noticed is that, while Flume will alert you if the Wi-Fi bridge goes offline, it does not notify you if the sensor itself stops reporting to the bridge. This happened to me twice: once due to a range issue and another time when the battery died. Although there is supposed to be a low battery alert, I did not receive one when the battery actually died. While flume saved me twice from leaks, I could have easily missed those leaks because the sensor went offline without being alerted. It is important to be aware of this gap and why I rated it as 4 instead of 5. **Awareness & Savings:** I haven’t noticed much in terms of day-to-day water savings, but I am definitely much more aware of my daily and weekly water habits. The detailed usage breakdowns and alerts have helped me understand exactly when and how water is being used in my home, which is valuable for long-term conservation and catching potential issues early. **Final Thoughts:** Flume 2 is a must-have for any homeowner who wants to avoid water damage, stay informed, and monitor water usage with minimal hassle. Highly recommended for its accuracy, reliability, and user-friendly design.

Default settings are not sensitive enough, make sure to adjust them
I had a higher end system installed in my previous home (Grohe Sense Guard), but it is super expensive and requires a plumber for installation. So I was looking for something to provide me with the piece of mind of having at least some sort of monitoring, without the cost and the installation complexity. I found this Flume 2 solution and it's so simpler and so much cheaper and I could not resist trying it out. Installation is super simple ! Just strap the unit around your water meter, install the wifi base somewhere indoor, and it works. I am super happy with it ! My recommendation is really to adjust the detection rules to be significantly more sensitive than the defaults. I think the manufacturer wants to avoid false alarms, but I see this device as a circuit breaker. When you install a circuit breaker, you choose a circuit breaker with a rating just above what can be safely supported. It is the same here : setup your usage alerts slightly above what you normally do at home (you can check after a few days of usage, what your usage looks like). For instance, if you take showers that last 15 minutes, setup an alert if water runs for more than 25 minutes (at any rate). Also, if your shower uses 2 gpm (for instance), setup an alert at 3 gpm for more than 4 minutes. This will help detect pipe burst and other significant leaks faster. This is in addition of the default alert which you can also leave enabled. The default settings is, I think 2 HOURS of continous water use. It's too long ! Make it more sensitive. Find the sweet spot where it is right above the normal usage, so you don't get false alarms, but low enough so that any abnormal water usage will trigger an alert. You can always make them a bit less sensitive if you do get false alarms. I don't mind dealing with a false alert every 2-3 months, it's easy to know if it's a false alert based on what you were doing (example: you were washing the car). Great device but just make sure to increase the sensitivity to get the most out of it. I also added a label on top of it that says 'Sensitive leak detection device - Do not move ! Homeowner's property" so that the person from the water company knows what it is and doesn't touch it. Also, Flume's tech support is super responsive in chat, if you ever need to talk to them, which is awesome. Overall I really recommend this product. It is not as good as more expensive solutions, but for the price and simplicity, everyone should have at least this. PS: Don't forget to call your insurance once you installed this, you might be eligible for a discount

Incredible Range
I was worried that my meter was too far away from the bridge and the water sensor. According to Flume the bridge and sensor can communicate upto 1000 feet away. My water meter is in an in ground cement vault and approximately 300 feet from the bridge. Keep in mind the operative here is UPTO 1000 feet depending on building structure, walls, fences, etc., etc. Much to my surprise it works. The bridge is in the garage and the sensor is in front of my neighbors house, probably about 300 feet away. The signal travels through two stucco walls and system works perfectly. I use the same Flume smartphone app for two of my homes and must say the programing is wonderful. Some of my friends think they don't need to monitor water leaks but here are a few scenarios that I have already experienced since installing my first Flume. 1) Flume app notified me of a leak. I shot the main water off to the house and the leak stopped. Turned the main back on, the leak started. Through a very tedious trial and error, it was a defective shutoff valve at my RO system under my sink. The exit line unloads into my sink drain under the sink, no sound, no puddles, just a leak. 2) A drip system valve wasn't closing all the way, the leak was so small, there was no visable water, Flume caught it. 3) Recently I was away on vacation (7 hrs from my home), my gardener left a water hose bib slightly on. Thankfully Flume sent me a notification and my good neighbor was able to turn the water off otherwise it would the water would have been on for a week. In closing, years ago before the Flume was installed, my wife and I headed off to work and discovered a water hose to the washing machine split and sprayed water for about 8 hours until we arrived home. Needless to say our home was severly flooded, ruined our carpeting and subfloor throughout the house costing thousands of dollars and inconvenience. If you find yourself thinking why would I need a monitor system, think Flume, it is a small price to pay for piece of mind.

I expected more from FLUME 2.
This is a first pass at reviewing this device. I will add to it when I learn more. It was recommended (but not sold) by an irrigation professional contact . Amazon got it to me in 3 hours and I installed it 5 hours ago. Reason for buying was having an alarm to notify me of a leak in irrigation system (common and cost/waste of water is the big motivator) or an alarm in terms of leak inside of house when I am away from home (cost of water damage issue) . Secondarily to look at useage in various branches of the irrigation system as well as pool evaporation. My meter is in a well in the front yard like many properties in the greater Phoenix area. The well is ~ 50 feet from the house. FLUME gives you a handy tool to open the lid on your well. The sensor simply straps to the meter and this takes 2 minutes. "Sensor" is a bit of a misnomer because it does not really sense flow direcly. It senses the rotating magenetic field of an impeller in the water meter. In effect eh FLUME sensor is eaves dropping on the flow meter in the water meter. Looking at Patent 10750253 confirms this. Clever! So you would think that clever scheme would then report 1:1 exactly the same flow rate as the water meter. FLUME tech support remotely ran a calibration (as a favor) while I asked them for support in getting the radio link working better. You would think that it would have been really accurate after a calibration by FLUME tech. FLUME now measures 100.8 Gal while my water meter reports 103.4 Gal. a -2. 6% error. I could live with that error in the auto calibration if they woudl give you some place in the UI to manually enter the 1.02579 calibration factor so that the meter an FLUME would read 1:1. But there is no way to enter a calibratin factor manually. The sensor is batery powered and has a low power 900 MHz radio transciever to communicate witeh the WiFi bridge. Thsi is challenging becsue the sensor is in a small well and has no direct line of sight. WAHt is really frustating is that they is no singal level indicator to aid yo in moving the WiFi Bridge around to get the best signal. You can't call FLUME. The only tech support is chat which is anoying becuse it seems tht the support person is trying to deal witeh 4 other people at the same time as you. So I tried the chat and could not convince the tech to give me some numerical readings. It turned into game of warmer - colder. Tech informs me that FLUME purposely left the signal strength indicator out of the UI because it was too confusing. Not sure whey they can't give us the 5 bars we have had on cell phones for 25 years. The warmer - colder over a chat was pretty frustrating. Eventually he shared the actual reading number with me and I got a better sense of what was making a bigger difference in increasing signal. And the sensor connected well enough to let FLUME tech do a calibration. I had really hoped to optimize the location of the Bridge because I did not want a marginal RF link situation with the radio doing a lot of retries and consuming the proprietary battery more quickly as well as possibly missing data. Eventaullay a tech lead got on the chat and things went a bit better. I ended up putting the Wifi Bridge in a second floor window witeh a better view into the well. But I had not yet put the concrete lid back on the well when the 7 pm cutoff for tech support happened. Is seems to be conneced now but not sure how robust it is without a signal level indicator. Will "chat" again tomorrow with support. Also , FLUME is limited to classifying water usage by various devices in the household. I had hoped to be able to have the 9 different sprinkler zones as separate elements of my irrigatin system to dermine say if if say one zone is leaking . It will not do that. You have to sort it out from the 1 minute resolutin bar graph on your phone (that can't be exported as CSV for analysis in Excel). I will add to this review as I live with it a bit longer.

THIS IS AWESOME
WORKS GREAT. Make sure your water meter is compatible, you have wifi available nearby. The app is great. This device won't shut your water off like more expensive competitors, however it will email/text you if there is a leak or high flow event. Great for monitoring water consumption and alerting quickly if you have a leak or leave a tap on. Customer service is very responsive. Highly recommend.

Useless in Europe
Even though they ship to Europe, this product only works in Canada and USA. In Europe it is completely useless and you will have no option other than to send it back

No es compatible en México
Te pide número de USA para crear la cuenta enviando un sms, también una dirección obligatoria de usa, ya después de eso resultó que mi medidor no es compatible y eso que tengo uno muy moderno.
