YoLink FlowSmart Kit: 0.75" Water Meter + Monitor + Hub

I installed this system on a vacation property with a home water system and two separate yard watering lines, all of which branch out from a central water line coming from city water. There’s a single main water meter and shutoff valve for the entire property, but it’s located several hundred feet away and takes some effort to access. To add to the picture, the property has had a history of recurring water leaks which cost the previous owner thousands of dollars in unexpected water bills. Needless to say, one of my priorities was to prevent this from happening again. After a significant amount of online research, I decided to try out the YoLink FlowSmart system. I consists of a battery powered control unit, a water monitor/meter, and a motorized ball valve. The control unit is directly wired to the monitor/meter and ball valve, and communicates wirelessly with a YoLink hub, which in turn is connected to my Wifi router. I installed the monitor and valve downstream from the main meter, just before the line splits off to the home and yard watering lines. This allows me to monitor water usage nearly real-time on the YoLink app, and to easily shut off the valve remotely if it detects any suspected leaks. So far, this has already helped me find one confirmed leak. I ran into one completely unexpected issue – a mouse chewed through the wire harness to the valve, disabling it. I emailed YoLink customer support for advice, and they responded within a couple of hours. They quickly FedEx’d me a replacement unit within a couple of days, which allowed me to get it operational again with minimal downtime. In the meantime, YoLink has quickly become the primary home automation solution for my vacation home – I’ve added water sensors placed underneath sink areas and by the washing machine which, if triggered, will automatically shut off the main water supply, as well as various motion sensors and outlet controllers. I also added a couple of temperature/humidity sensors and two garden sprinkler controllers to fully automate the existing 9-zone water system. All of them are easy to pair, have a much longer range than either direct Wifi or Z-Link, and have an impressive battery life. I will likely add two more YoLink water valves to give me additional flexibility in isolating different sections of the water system. Overall, I highly recommend this as a home automation system that’s very functional, easy to set up and use, and especially shines for long-ranges. Positives: * Easiest pairing and inclusion process of any home automation system I’ve tried so far * Long range far surpassing WiFi and Z-Wave is great for larger properties (I’m using motion sensors on the far side of a 5-acre lot with no connectivity issues) * Long battery life * Large selection of other home automation sensors/controls to expand system * Great customer support * Functional, easy to use app * No ongoing subscription costs! Downsides: * Water valve wire harness is a bit on the delicate side for an outdoor installation – recommend additional wire shielding to slip over exposed connections (easily found on amazon) * Would be great if app provided more options in customizing the home screen layout in the future

I have a slow leak based on my increased water bill. So I installed this meter right outside my house. This has allowed me to determine that the leak is most likely past my shutoff, and unfortunately probably under my slab. (I can see that the leak is not in my yard between the water company meter and the side of the house). Positives: - Fairly easy to install. I had to dig out a hole to put it in, and also installed an in ground meter box. (note: I had a nice straight run of pipe to put it in, which is required to have accurate measurements) - No additional power wiring required on the outside of the house - The digital part that goes on the outside of the house uses standard AA size batteries (requires lithium AA batteries but comes with them). - The part that goes inside the house uses a standard USB plug and includes both WIFI and Ethernet port. I did initial setup with Ethernet and then was able to put the WIFI on my guest network (did not require local LAN access). Works fine with the Ethernet cord unplugged. - Both the Yolink hub and the outside digital part of the meter paired easily with the Yolink app (Android phone, app is in the play store). Paring is done by scanning a QR code, first on the Hub. And then later scanning the QR code on the back of the digital part of the meter. - Customer service responded very quickly to my feedback about the app. Negatives: - You only get a total water used amount and not a flow rate, where the water company meter gives GPM (you can select the units between Gal, L, CCF, M3). - My leak is too slow to be continuously monitored by the digital part. If I am not using water, my leak shows up as a periodic blip once an hour of about 5 gal. The meter is still measuring the amount, it just doesn't get reported on the app constantly. This is also kind of a feature because it helps preserve the battery life. - The wiring between the flow meter and the digital part that stays outside could be better. It comes with generic WAGO type connectors to connect between the digital part and the meter. There is no enclosure for this connector and it is left exposed. I kind of want to get an external box to put the digital part in now even though it is IP66 rated. - The app is not very intuitive. It does have quite a few features (it is designed to work with other yolink devices, but I only have the water meter). I was hoping to share the device with another user. I initially didn't see any option to do this in the app. So I submitted feedback that the functionality should be added. Yolink responded with instructions on how to set it up, since the feature was already there.

163k gallons of water have passed through my YoLink YS5006 Meter (see pictures). The valve is super reliable with its long range signaling. I have it hooked to my smart home and if my water sensors (also YoLink) detect a leak being fed from the city water, I shut off the main line and alert (SMS and voice announcement). The valve was very easy to install in my PEX pipes. I did build a little support to hold the electronics, and I did have a convenient plug already up next to my water heater so it was very easy to give it power. I would give it 5-start EXCEPT I have a Hubitat system, and YoLink is not supported on Hubitat (My understanding is that this is a YoLink choice). As such, am also running HomeAssistant because YoLink has chosen to support HA. Then I bridge HA to Hubitat so that a YoLink alert notifies HA that, in turn, notifies Hubitat, so I can do things like speak an alert with the integrated Sonos speakers. I wish I could just have the YoLink hub interface directly with Hubitat! I also interface directly with the valve via the YoLink App that talks to the YoLink hub. The App gives me a leak alert on my phone when there is water running when it shouldn't be or when the water has been running for too long continuously (so really it's just an alert that my child is taking a shower :( ). Would recommend! 2026.07.13 Update - Thanks to Steven Barcus for providing his YoLink Meter Controller Hubitat support I'm upgrading my review to 5 stars! Just go to the Hubitat Community and search for his name or "YoLink™ Device Service” app and drivers to connect Hubitat™ to YoLink™ devices" to find the driver and installation instructions. I've powered down my Home Assistant for now, because I was just using it to support this meter. 2026.07.14 Update - And down 1 Star after raising due to Hubitat support . . . Physical Meter Readings and Digital readings do not match! I think the odometer looking one is frozen. The clock dials are closer but they don't match the digital reading (though the are closer). I'm not too concerned for my use case (knowing when to replace whole house water softeners), but this is still not good.

I am very happy with this YoLink system and am confident it will stop damage from the most common water leaks near or around faucets and water connnected appliances plus my HVAC condensate. I have installed sensors inside vanity or cabinet under each sink, under the refrigerator with icemaker, under the dishwasher, clothes washer, around the base of each toilet, water heater, and near every shower and tub. I have also installed where condensate drains / pumps could backup or overflow. The system provides an alarm on each identified smart phone, a local alarm and I have programmed the system to immediately shut off the home water supply when a leak is detected (other than condensate leak since that is not from the water supply). I have tested the system and it seems to work very well. While a full coverage system like this with a lot of sensors is expensive, its still much less than the deductible for my home insurance and most insurance policies don’t cover damage from plumbing and appliance leaks anyway. Its also convenient to be able to shut off the whole home water supply from your smart phone when doing any plumbing maintenance or installations.

I installed this back in May. Install was pretty straight forward. I'm using it for leak detection. But it is, also, nice to have just to see what kind of water usage my house has. So far so good.

I works perfectly. One of my DYI project for my home. I bought it because I have problem with the Septic System and the builder says that the RO filter under the kitchen sink is causing the problem. I have well and one of the option was to put a water meter to measure the incoming water to the house. I look all the data from my telephone app and printed all the data needed to fight the problem. I recommend it.

This Smart Meter/Shutoff has so many features. Tied to sensors under water sources, it will trip the valve upon water sense (yes, it works quickly, Ive tested!!) Also, you can set to trip valve on Continuous Water Usage (i.e - 25 Gal have flowed continuously because you left shower on) OR Continuous Water Usage Duration (i.e. - water has been running somewhere for 30 minute). Feel very confident in the leak protection this device offers. Also, being able to track my water usage is great. BTW, the App works great!!

Cannot get the digitall measurements in the app

Excelente, fácil de instalar y de monitorear. Permite tener en tiempo real la información.

Instale el medidor, seguí las instrucciones, baje la app, detectó ambos módulos y sin embargo ya tiene más de 48 horas y al consultar lecturas en la app y marca 0. En el medidor físico si mide el agua que va a los tinacos.
