1 What type of WiFi does the detector work with?—A—:The detector’s gateway is compatible with 2.4GHz WiFi networks only and does not support 5GHz. Please use the “Tuya Smart” app for setup and connection. 2 Does the hub/gateway always need to be plugged in to operate? If not, how long can the battery keep it running before it shuts down? —A—:Yes, the hub/gateway must be plugged in to function continuously. It has a built – in battery backup that can maintain its operation for around 10 hours during a power outage. 3 What is the volume of the water alarm, and is it adjustable?—A—: Yes. The water leak detector features a 120dB alarm with 4 volume levels available. Additionally, the gateway emits an alarm with a volume ranging from 0 to 90dB. You can silence the alarm either by pressing the sensor button or through the app. 4 Can I set up a schedule for arming and disarming? —A—:Absolutely! You can set up arming and disarming schedules through the app. Tailor the settings to suit your preferences, like disarming during nighttime or on rainy days. 5 If I’m driving or out and about, and my phone is only using cellular data, won’t I receive an alert?—A—You can receive real – time alerts from the app anywhere, as long as your phone is connected to a cellular network or any other Wi – Fi network. 6 May I share the device among my family members?—A—:Yes, you can easily share access to the device through the app, allowing your family members to monitor the system and receive alerts as well. 7 What happens if the detector finds a leak?—A—:Upon detecting a leak, the detector sends an alert to the gateway, which then notifies you via your phone. The range extends up to 328 feet (1/4 mile) outdoors, though indoor ranges are generally under 150 feet. 8 How many sensors can be connected to the gateway? —A—:You can connect up to 24 WD71 water sensors to the gateway/hub for consistent monitoring. Note that it does not support other water sensor models. The Tuya app also enables the setup of up to 20 Wi-Fi gateways. 9 What occurs when the batteries are low? Can the water sensor operate independently?—A—: The leak detector will notify you with a low battery alert. It operates on 2x AAA batteries, which are provided with the device. Each water sensor is equipped with its own speaker and batteries, allowing it to sound an alarm independently, even without a Wi-Fi connection. 10 How can I distinguish each water sensor in the app?—A—:Each water sensor is pre-assigned a serial number (01, 02, 03, 04, 05). By pressing the TEST button on a sensor, the app will send a notification like: “WIFI Alarm System: 01 triggered the alarm” or “WIFI Alarm System: 02 triggered the alarm,” and so on. You can then rename each sensor in the app for easier identification. 11 Is there a charge for the app?—A—:The Tuya Smart apps can be downloaded and installed free of charge. The app push notification with our water alarm gateway is free. However, other types of notifications within the apps, like SMS and phone call notifications, are chargeable (this service is not included).
Reliable 2.4GHz WiFi Connection: This water leak detector set supports 2.4GHz WiFi networks only. Effortlessly connect the gateway to the “Tuya Smart” app via WiFi to safeguard your home 24/7. The gateway ensures a stable connection for up to 24 WD71 water sensors. Note: Not compatible with 5GHz WiFi
Instant Leak Alerts: When a leak is detected, the sensor triggers an alarm and sends a signal to the gateway (up to 328 ft in open areas; typically 150 ft indoors). The gateway instantly pushes notifications to your phone via WiFi, alerting you even when you’re away. Share the device with family for real-time monitoring from anywhere. Note：TUYA app push notifications are free — such as alerts appear on your phone’s notification bar and lock screen. However, SMS and call alerts are charged by a third-party TUYA publisher, not RUKORING. Please consider your needs before enabling these services.
Customizable Scheduling: Arm or disarm the detector automatically using the app’s timer feature. For example, disarm it at night to avoid disturbances or skip arming on rainy days for added convenience.

Wifi water sensors provide peace of mind with instant alerts
I ordered these water sensors for peace of mind of being notified of a water leak in our bathrooms or kitchen in our home. Without physically looking under each cabinet, there was no way to know if there were any leaks, but these sensors provide that assurance of knowing when or where or if there is any water detected and it’s all through an app on the phone.It’s easy to install the batteries in the water sensors. I like how easy it is to test the sensors for water detection so I know they really work before placing them under the cabinets. To test each sensor, I put a thin layer of water in a small saucer plate and dipped each sensor’s metal contact feet into the water. Each sensor emitted a warning tone as intended.The mobile app is pretty straight forward to set up though the printed directions are not very well translated from the original Chinese. When I got the app installed on my phone and turned on location services, the five sensors were identified in the Water Sensor portion of the app. There is no hardware data in the app for detected devices so it’s difficult to determine which device is shown in the app. To determine the device, I ended up deleting each water sensor from the app and then testing each in the saucer of water to see which device showed up on the app. I then gave that sensor a unique name in the app and wrote a number on the device to make it easier to identify its location in the house.The included wifi hub works well and connects to the 2.4 Ghz home network quickly. It has a short duration internal “keep alive” battery, but the hub must be plugged in full time to monitor the sensors, which makes sense. It would be nice if the app included a battery life level for the water sensors.I like how easy it is to set up, and these sensors work well in sending a notification to my phone of even a tiny bit of water. This system is a great value for the money and provides peace of mind with this unique design of an app and water sensor duo.I highly recommend these water sensors.

Water Leak Detection System Connected to your Phone
5 for now, but I just received the device, so I won’t be able to report on longevity. Perhaps I could follow up in a year or so. The device arrived quickly with no issues. It has a main base station that can be plugged in for assurance of power. It can run on its own when charged as well, but I have no experience for how long it can hold a charge.I ordered the device with 5 leak sensors running on 2 AAA batteries that were included and came with a full charge. These sensors came already paired with the base station which made setup much easier. I just had to download the Tuya App to my phone and then plug the base station in, turn it on, then search for my WiFi and enter the password when prompted. That all worked flawlessly. Then, after loading each sensor with its batteries, I tested each one with the base station armed. The base station sounds loudly and each sensor when tested has a high pitched sound for 1-2 seconds when tested. If the sensor doesn’t stop on its own, press the test button again to turn it off.I placed my sensors in the drip pans for water heaters and AC pans to give me a head’s up on these devices which largely sit in attic spaces in Texas. I also placed one behind the toilet for early leak detection here. You could place them near a washing machine or dishwasher as well. Just place them where your concerns are greatest. These sensors are nice in that they can detect a drip coming from above the device (top of the sensor) and they have metal feet that detects water puddling underneath the sensor.The Tuya App allows you to arm and disarm the base station. It records the history of each sensor and when it sounded. Each sensor can be renamed in the App, so you will see exactly which sensor sounds when you get notified on your App of a triggered sensor.The only variable for each house is where is your WiFi base station? The base station for this leak detector system must be able to get a good signal from the WiFi in order to detect the sensors and send that message to your phone through the App. This might require a bit of trial and error on your part to optimize the location of the base station and its proximity to your sensors. Be sure to test each sensor with the base station armed to both hear it sound the alarm and for it to send that message to your phone. I actually had no issues with where I placed the sensors relative to the base station. It read the sensors in my attic as well as the sensors in the downstairs bathroom.This system was fairly easy to setup (came with a simple instruction booklet), it operated exactly as advertised and so far I am pleased with its functionality. Only time will tell on how well the system works over time. For now, I feel like we have an early warning system in place that will let us know of a problem when we are at home or traveling.

Great product when looking for peace of mind when it comes to household water leaks
We have purchased this WiFi Water Leak Detectors, after hearing how our neighbor’s water heater leaked slowly and destroyed all first floor flooring. It’s nice that they come in set of 5. We put them by water heater and in the bathrooms to catch any toilet/sink water leak before it would get thru the walls. Also, we put one in the kitchen, strategically placing it btw sink and dishwasher. We already have a detector for a/c leak in our attic, but if we didn’t – we would put one there as well. They were very well packaged. Arrived very quick and set up is very simple. Tested all of them on very wet paper towel and they are all working and all detected water. Best thing is that they will alarm us real- time on our phone remotely, which is great when we are away from home.Setup was straightforward, and connected to our Wifi network easy. The 120dB alarm is pretty loud, so that we’ll be alerted immediately in case of any water leaks.This is a fantastic investment for our home protection, to prevent any water damage from small leaks that can become a big and expensive problem. We highly recommended for anyone looking for peace of mind when away from the home.

Great detectors, peace of mind
These are just what I was looking for. Needed water leak detectors that can be set on mute. I have a kid whose very sensitive to alarms, like the smoke detector terrifies her. I set all 5 on silent mode and also set the base on silent mode. It simply sends alarm notice to my phone, plus the base blinks for a visual. Was so easy to setup and they all work just fine. Placed in 2 bathrooms and kitchen and basement near humidifier pump. 🙂
