Rapidly alerts you to the presence of water anywhere it shouldn’t be
Integrates with Ring Alarm Pro and Ring Alarm security systems
Leaks detected can trigger an intelligent water valve to shut down your water supply
Of no value if you don’t have a Ring Alarm or Ring Alarm Pro security system and a subscription
Low temperature threshold set at 40 degrees Fahrenheit
Doesn’t monitor ambient humidity
A well-designed product that adds a new aspect of protection to Ring’s home security systems, the Ring Flood and Freeze Sensor works as advertised. But it’s not unique by any means, and it requires either a Ring Alarm or Ring Alarm Pro.
Ring Flood and Freeze Sensor: Best Prices Today
Water damage presents a bigger threat to your home’s security than a break-in, fire, or any other peril. If you’ve already invested in a Ring Alarm system, adding the low-cost Ring Flood and Freeze Sensor is a wise investment. It can not only alert you to both the presence of water anywhere it shouldn’t be, it can also warn you of low temperatures that can lead to frozen water pipes at risk of bursting.
This sensor is not an independent device. You must have either a Ring AlarmThe following are some examples of how to use Ring Alarm ProRing Protect subscription with a home security system. Both Ring systems perform better as security platforms rather than as smart home hubs. However, they can still handle the basics of the latter category. The Pro model also integrates a Wi-Fi 6 router and several other features you won’t find in the cheaper version.
You’ll also need a Ring Protect subscription ($4, $10, or $20 per month) to receive the sensor’s in-app alerts. If you have either of the also-required Ring security systems, you’re probably already paying for the top-tier Ring Protect Pro subscription, which includes professional monitoring that can dispatch first responders in the event of a police, fire, or medical emergency. Note that a Ring Protect Pro membership is required to receive automated phone messages when the sensor detects either water or freezing temperatures. If the number listed as your primary contact doesn’t answer, the secondary contact you’ve provided will be called.
The Ring Flood & Freeze Sensor is a disc that measures 2.95 by 2.95 by 1.06 inches (HxWxD), or 75 x75 x 27mm. It has four metal contacts on the surface facing the floor. The sensor’s bottom half has a scalloped border that allows water underneath. It’s powered by a single 3V C123A lithium battery that Ring says should last three years.
The sensor uses a Z-Wave Plus to communicate with the Ring Base Station. This is one of the reasons for the long battery life. The sensor spends most of its life in a deep sleep, waking only to verify its connection to the network or when it’s triggered by the presence of water or ambient temperature below 40 degrees Fahrenheit (4.4 Celcius).
Some of the competing devices I’ve reviewed—including the Phyn Smart Water Sensor, which also tracks humidity levels—allow you to choose custom thresholds. Ring chose 40 F as a threshold to give you enough time to act, before your pipes begin to freeze and burst. If you find Ring’s sensor is sending too many freeze alerts, you can turn them off. We’ll get to that in a moment.
You can deploy these sensors at any indoor location where there’s a risk of a water leak from a supply line or a drain: Under a sink; next to a toilet, water heater, washing machine or dishwasher; near your basement sump pump; and so on. Ring only requires that the sensor be within 250 ft of a Ring Base Station.
Since Z-Wave is a mesh network topology, it’s easy to extend that range. You can either deploy any other Ring-compatible Z-Wave device (anything from a smart light bulb to a door/window sensor) between the flood/freeze sensor and the base station, or you can buy Ring’s Z-Wave range extender ($25). Ring Alarm starter kit includes one of these pluggable devices. You can add as many extenders as needed.
Ring Flood and Frozen Sensor Setup
Add a Ring flood and freeze sensor to your Ring Alarm system by launching the Ring Alarm app, clicking on the Set Up a Device icon, selecting the Security category, then selecting the Scan a QR Code option in the top menu. Scan the QR Code on the box or a slip of paper in the box. You can also scan the QR Code on the device. Then, follow the instructions on screen. This includes identifying the location where you’ll place the sensor and, optionally, assigning it a different name from its default.
The sensor arrives with its battery pre-installed, but you’ll need to remove the plastic tab between the battery’s positive pole and the sensor’s positive contact to activate it. When you do that, your Ring Alarm system will verify that it’s within range of your base station and add it to your Z-Wave network.
You can customize the way that the sensor alerts to temperature and water leaks. You can select to receive low-temperature alerts or water detection alerts. I’d recommend enabling both, at least until you know how mYou can also find out more about the following: nuisance temperature alerts you get. Not getting anyThe purpose of a sensor is defeated if it alerts.
The alert options are a Ring Protect Pro Subscription, a Ring robocall, or an email. You can also opt to get a “chirp tone” notification at the Ring Alarm keypad, or either a spoken notification or a chirp at the Ring Alarm base station. The latter alerts will be repeated every five minutes, until they are cleared.
Ring Flood and Freeze Sensor User Experience
I tested the Ring Flood & Freeze Sensor using a Ring Alarm Pro Home Security System and a Ring Protect Pro Subscription Plan. I poured some water into my sink and placed the sensor on one of the residual pools. The sensor is not sufficiently weatherized to survive submersion or withstand water hitting it from above, but that shouldn’t be a problem as I almost immediately received all the notifications I’d signed up for: a phone call, a notification in the app, and a voice alert at the base station. I removed the sensor, dried its contacts and dismissed the alert.
At least I Think about it I’d dismissed it. The LED light ring on top of the Ring Alarm Pro base station continued to pulse, and the station repeated its spoken notification five minutes later, and then five minutes later, and then five minutes later…. I finally Googled how to clear the notification and was rather embarrassed to learn that I needed only to look at the front screen of the Ring app, where a large “Water Detected!” alert appeared at the top, with a nearly as large button labeled “Take Action.” Tapping that button finally took me to a screen where I could FullyClear the alert. I could have also snoozed and been reminded 4 or 8 hours later.
You can access a dedicated page for the Ring Flood and Ice Sensor in the Ring app by tapping on the icon of your Ring Alarm system, and then tapping its name from the sensor list. Here you’ll find an icon representing the sensor’s battery level, and tiles for various settings specific to the Ring and Flood Sensor, including one that displays an event history when tapped. Here you’ll see a chronological list of events, everything from settings changes to status changes, but most importantly, the dates and times leaks were detected and when they were cleared.
Should you buy Ring Flood and Freeze Sensors?
The Ring Flood and Freeze Sensor is a well-designed product that adds a new aspect of protection to Ring’s home security systems. It works as advertised, but it’s not unique by any means. You’ll find our Top picks for water leak sensorsAt the preceding link, you can find several options that can be used on a standalone basis.
One of the features that does enhance the value of Ring’s product is its ability to trigger a smart water valve—such as a Flo by MoenOr a Zooz Titan Water Valve Acuator—to shut off your main water supply if a leak is detected. If you’re away from home and one of your water pipes breaks, your toilet overflows, or any other malfunctions occur, shutting off the source of the water will greatly mitigate any ensuing damage.
But it bears repeating: Don’t buy a Ring Flood and Freeze Sensor if you don’t have—or intend to buy—a Ring Alarm or Ring Alarm Pro system.
