Introducing, the EVO Line of Valve Operators & Motorized Valves
The EVO Valve Operator (shown): An innovative departure from traditional bolt-on ball valve operators, robots and valve manipulators. The EVO replaces your ball valve handle and attaches directly to the ball valve. This virtually eliminates issues experienced with larger, older, and/or stiffer valves, that "push/pull" mechanisms can struggle with. Economical, simple, no-plumber-required DIY installation, dependable smart water control. It's an EVOlution in smart water control, and an essential part of your water leak detection and automatic shut-off protection system!

water leak & flood sensors
rope style water sensors:
learn:
The Water Leak Sensor 2 is our rope style water sensor. The rope/cord has an absorbent water-permeable braided jacket, that allows water to penetrate the jacket and complete an electrical circuit that is detected by the sensor. The sensor then reports the status change from normal to water-detected, which results in notifications being sent to you, activating a siren, turning off the water, etcetera, based on your predefined preferences in the app settings.
Rope type water sensors are ideal for detecting water in confined spaces, such as behind a refrigerator or under a dishwasher. They can also be used to detect water within a defined area or region, such as around a water heater or laundry machine, or within a large region, when additional cords are added. See the applications images for examples.
Rope style water sensors are not ideal for water level monitoring. See our water level monitoring sensor selection for this application. Rope style water sensors are also not ideal for high-humidity environments. Consider one of our puck style water leak sensors for high-humidity environments.
The Water Leak Sensor 2 has an integral piezo sounder (mini siren). The sounder can be enabled or disabled in the app settings. Not using the sounder will maximize the life of the batteries. It is not recommended that the sounder on the sensor be the sole means of notifying you of a leak or flood. Please note: it is not recommended to rely solely on the sounder on a leak sensor, as you may be asleep and several floors and/or closed doors away from the sensor when it activates. Consider the Siren Alarm, the SpeakerHub (e.g. on your nightstand), the Critical Alerts (severe weather style notification that activate audibly, even if the phone is in Focus or silent mode, available only to iOS phones), or app-specific notification settings that are loud enough to wake you, should be considered as primary methods to get your attention, even if you are asleep.
This sensor should go upwards of 5 years between battery changes. Compare that to competitor products like those from Govee, that may need to be replaced as often as every 90 days!
Tip: the cable/rope can take an extended period to dry after getting wet. It is recommend to have a spare cable on hand, to replace the wet cable, after the leak or flood has been removed. Additional cables are available to purchase in the accessories section below.
The Leak Sensor 2 comes with a metal hangar, with 3M mounting tape pre-affixed, to hang it from a wall or other surface. See the optional ruggedized Wall-Mount Bracket for this sensor, which is ideal when the sensor is used at public locations, in apartments and rental properties, like condos and BNBs. The bracket, which can be screwed or adhered to the wall (screws included, other methods such as mounting tape, not included), affords the sensor additional protection against impact, casual tampering and cord removal.

puck style water sensors:
learn:
The Water Leak Sensor 1, Water Leak Sensor 4 and Water Leak Sensor 4 MoveAlert are our "puck" style water sensors. Puck style water sensors are typically placed on the floor, where leaking or flooding water is expected. It has water-sensing electrodes on the top and bottom. The bottom electrodes are optimized for detecting flooding or pooling water, while the top, with its cupped region, is optimized for dripping water.
A unique aspect of our puck style water sensors is that they are waterproof. It might be surprising to learn that many smart water leak sensors can be damaged by getting wet. Our puck style water sensors will not need to be replaced if they get wet.
When a sufficient amount of water is on or under the sensor, water creates a closed electrical circuit between a pair of electrodes. The sensor then reports the status change from normal to water-detected, which results in notifications being sent to you, activating a siren, turning off the water, etcetera, based on your predefined preferences in the app settings.
Our selection of puck style water sensors are nearly universal water sensors; they can be used in almost any residential application. Spaces may be too small for a puck sensor, so you might consider the Water Leak Sensor 2, our rope style sensor. For air condensate pan or pipe overflow/back-up detection, consider our Water Leak Sensor 3 (our probe cable style leak sensor), or our Water Level Monitoring Sensor (with float switch). The Water Leak Sensor 3 is also more ideal for laundry machine water drain pipe back-up/clog detection. See the below sections for more information on these sensors.
Unlike the Water Leak Sensor 2, the 1 does not have a built-in piezo sounder (mini siren). The new puck style sensors, the Water Leak Sensor 4 and WLS 4 MoveAlert do have integral sounders. Please note: it is not recommended to rely solely on the sounder on a leak sensor, as you may be asleep and several floors and/or closed doors away from the sensor when it activates. Consider one of our sirens, the SpeakerHub (e.g. on your nightstand), the Critical Alerts (severe weather style notification that activate audibly, even if the phone is in Focus or silent mode, available only to iOS phones), or app-specific notification settings that are loud enough to wake you, should be considered as primary methods to get your attention, even if you are asleep.
The Water Leak Sensor 2 has an integral piezo sounder (mini siren). The sounder can be enabled or disabled in the app settings. Not using the sounder will maximize the life of the batteries. It is not recommended that the sounder on the sensor be the sole means of notifying you of a leak or flood. Since you may be asleep at the time, and the sensor may be on another floor, with several closed doors between you and it, it may be unlikely to awaken you. Recommended notification methods, include but are not limited to Critical Alert (iOS devices) and loud tones for push notifications on your smartphone, the SpeakerHub (audio, talking- and sound/tone-playing-hub), and the indoor Siren Alarm.
This sensor should go upwards of 5 years between battery changes. Compare that to competitor products like those from Govee, that may need to be replaced as often as every 90 days!

About available water sensor accessories:
The Water Leak Sensor 2, our rope style sensor, comes with one 47" (1.2 meter) cable. Additional extension cables can be added to the end, or the cable can be replaced with a 10' (3 meter) cable. The total length of the interconnected cables must not exceed 30' (9.1 meters). Please note: the longer the cable, the increased sensitivity to high humidity.
The Water Leak Sensor 2, 3 and the Water Level Monitoring Sensors, which all share the same main sensor body, come with mounting hook, with 3M brand mounting tape. The sensor hangs on this hook, which is adhered to the wall. For a more robust wall-mounting method, with increased resistance to impact or tampering, consider the optional Wall-Mount Bracket. The bracket also secures the cable to the sensor, preventing accidental removal of the cable. The bracket can be mounted to the wall with the included screws and anchors, or with any mounting tape or similar method (tape not included).
water depth/level sensors
water depth sensors:
learn:
The Water Depth Sensor is capable of measuring the depth of water and displaying it on the app. Your predefined high and low water level alerts can be used to trigger a notification, as well as automations and device actions (e.g. turning on a siren or a switch).
The Water Depth Sensor consists of two main parts. The sensor body contains the "brains" of the sensor, the batteries and the radio transceiver. The probe is a "throw-in" style, pressure-sensor transducer, on a 16.4' (5 meter) cable. By "throw-in" it means the sensor is simply dropped into the tank, container or body of water. The probe should sit at the bottom in a vertical orientation. The sensor measures the pressure of the water, which is translated into a length. The sensor will report the water depth from its location to the water surface, meaning if it is not placed at the bottom, it will only report water depth from its position to the water surface.
At this time (6/30/2023) the sensor displays depth in centimeters, only. The sensor is optimized for freshwater, with no options to calibrate for saltwater, septic tank water, milk, etcetera. The ability to adjust for different fluids, and to display the depth in imperial figures is expected in a future update to the app. If used in other than fresh water applications, an approximate depth can be manually calculated by using the specific gravity of the fluid multiplied times the displayed depth. A 32' (10 meter) long cable option will be available soon.

water level sensors:
learn:
While our Water Depth Sensor can measure the depth of water, water level monitoring sensors monitor or indicate only that that the water is detected at a specific level - this specific level being defined by the position of the float switch or probe cable. While several sensors can be installed at several heights, allowing you to know that the actual water level falls within these heights, only the Water Depth Sensor can indicate the exact water level. Both types of sensor can alert you or take device action upon low or high water level alerts, but the Water Level Monitoring Sensor can only be selected to alert on high or low water level. See the individual product page, or the product support page, for more information.

water flow/water meter sensors
learn:
Our new line of "FlowSmart" products now allows you to add water metering features to your YoLink single-family residence, multifamily residential, and commercial applications. The FlowSmart Control products come in a kit that includes a smart wireless meter & valve controller, water meter, and motorized valve. The Control line offers both water monitoring/measuring and leak detection.
The FlowSmart Meter products come in a kit that includes a smart wireless sensor and water meter. The Meter line offers similar water monitoring/measuring, but does not incorporate leak detection.
We do not recommend relying only an inline water flow sensor or meter for water leak detection. The best and most accurate (including most false alarm-immune) systems incorporate physical water detectors.
[This is a new product, released 11/5/2023. Additional information, videos, and other resources will be added soon!]
applications:
Applications include water use management and water conservation, in residential and commercial locations. The Control product line, that includes water metering, as well as leak detection and smart/automated water valve control, is our most comprehensive "Smart Water Solutions" offering, once physical water sensors are added to the application.
The Meter line may be a suitable choice if leak detection is not required and/or if a smart water control device (like a motorized valve or EVO Valve Operator) is already in place.

temperature & humidity sensors
temperature & humidity sensors:
learn:
Humidity can be used as an early warning of water leaks and flooding. Water or sewage seeping through walls can increase the room humidity levels, which can be detected by a humidity sensor. And, generally, high humidity levels can lead to the growth of mold and mildew.
Temperature sensors can be used to provide early-warning against freezing temperatures. Prevent water pipes from freezing when you monitor the temperature of at-risk locations. Whether in a region subject to freezing temperatures, winter storms and power outages, and/or properties not occupied year-round, such as rental properties, hunting cabins, etcetera, "freeze alert" sensors can be deployed to provide early-warning notification, so you can prevent damage and property loss.
