Water Leak Sensor

  • Question: Push notifications are great, but if I have a flood, or leak in the middle of the night how do I get the notification to make a sound?

Answer:

Really sorry YoLink Water Leak Sensor itself does not alarm. It only sends push notifications.
It works with Alexa, so you can create routines to get voice announcements. You can visit How to set up YoLink Water Leak Sensor on Part 4 – Alexa Integration to learn how to create routines on Alexa app. We have a YoLink Siren which works with YoLink Sensors and sends audible alarms. Its Link: https://www.amazon.com/dp/B0887SMPKK

What’s more, the reasons why the Leak Sensor doesn’t have audio itself are firstly we make the leak sensor water-resistant and also make its battery life last more than 5 years; Secondly, if the leak sensor is placed in a basement or other remote location, the sound may not be heard all the time.

Therefore, we have made the YoLink Siren Alarm, which can support up to 128 YoLink Sensors. The Siren Alarm can be placed wherever you like. When any leak sensor detects a leak, the Siren Alarm will emit a loud sound so that you will never miss any water leakage warning.
At the same time, the Siren Alarm can also be linked to YoLink motion sensor or YoLink door sensor. Even when the internet or the power is off (the optional two AAA alkaline batteries must be installed), the Siren Alarm can still work normally with YoLink water leak sensor using our unique YoLink Control.

If you are using the Android system, you can set the ring for your App notification on your phone settings -> Sound and Notification; Apple has disabled the notification settings.

 

  • Question: Why do I get so many alerts? When I dip the sensor in and take it out, I am getting many alerts/notifications (like 3-5 alerts). Seems like there should be a “de-bouncing” or something that prevents duplicated messages that occur within a certain time period.

Answer:

There are two reasons: Firstly, “The Alert Interval” has been set too short in the continuous alarm interval; secondly, the intermittent water detection: Detected -> Some seconds -> Not Detected -> Some seconds -> Detected. For the second reason, we need to confirm.

You can turn on “Do Not Disturb” on App -> Settings -> Alarm strategy of device, then set the time you do not want to get notifications. Please note that this function is applicable to all sensors. You can set different alarm strategies for different sensors.

 

  • Question: How do I use Alexa integration, use a routine?

Answer:

Please visit the Part 4 – Alexa integration on following video about how to connect and create routines for YoLink Water Leak Sensor

 

  • Question: Can this device be paired directly using ‘if/then’ or controlled through Alexa to trigger an automated 1″ shut off valve? If so, which brand of valve?

Answer:

Yes, this device can be paired to trigger an automated 1″ shut off valve. In addition, you can use YoLink Smart Water Leak Sensor to trigger the automated valve through IFTTT app.

 

  • Question: It is too late now for you to change but the vocabulary (opened/closed) for sensor status on creating a routine does NOT match the vocabulary (normal/warning ) in the YoLink app. The same vocabulary should be used everywhere. In any case, Opened/Closed is very confusing as I expect it refers to some electrical connection inside the water leak sensor and is not intuitive to a typical user.

Answer:

The word “Open/Close” on Alexa routine cannot be changed, as this is an Alexa matter. In Alexa, there is no independent event for the water leak sensor. We use the same event as the door sensor to make the water leak sensor support Alexa.

 

  • Question: I added the devices to Google Home, but I didn’t see any way to make Google Home give me an audible alarm in case of a sensor detecting a leak.

Answer:

Google does not support voice announcements for smart sensors at present. Google only supports querying the status of the device.

Only Alexa supports creating routines to get voice announcement when there is a water leak detected.
Please visit the Part 4 – Alexa integration on following video about how to connect and create routines for YoLink Water Leak Sensor

 

  • Question: I would like to get a phone call if a water leak is detected 

Answer:

You can turn on SMS notifications in the YoLink app.

Or, you can connect YoLink Water Leak Sensor with IFTTT, and create IF “the water leak sensor leak warning” then “Call you”.
Please visit the following video on Part 5 – IFTTT Integration to know to how to connect YoLink Water Leak Sensor with IFTTT

 

  • Question: Is there a way to reset the sensor itself? 

Answer:

You can press the “SET” button and hold it for 20-25 seconds, which will restore the sensor to factory settings. Then, press the “SET” button, the water sensor should return to normal.

Please dry the leak sensor probe to ensure that the leak sensor is completely dry and the alarm is restored.

 

  • Question: Can it be used in something that moves – boat at my dock?

Answer:

YoLink Hub is required to use YoLink Water Leak Sensor. YoLink Hub needs to connect to the router via wired connection or 2.4G Wi-Fi to connect to the Internet.
If you have a Wired or 2.4G Wi-Fi connection on your boat, then your YoLink Water Leak Sensor will be ok. Any set of probes on the sensor can detect water, YoLink Water Leak Sensor will push notifications from the YoLink App.
If you don’t have a wired or 2.4G Wi-Fi connection on your boat, you can use YoLink Siren alarms with YoLink leak sensors to get audible alarms through YoLink Control. But you will not receive notifications from YoLink App. Link of Siren Alarm: https://www.amazon.com/dp/B0887SMPKK

Please note in an open air, the communication distance between the leak sensor and YoLink Hub and YoLink Siren Alarm is up to 1,000ft.

 

  • Question: Any tricks about removing the silicon dots to replace the batteries?

Answer:

Regarding removing the silicon dots, the Leak Sensor is a device with high waterproof level requirements, which requires water-tightness. It is not recommended that users replace the battery by themselves.
The batteries of YoLink Leak Sensor last for 5 plus years with normal use.
If you really need to replace it, it is recommended that you can use a thin pin or needle to remove the footpad. After replacing the battery, the reinstallation of screws and footpads may affect the waterproof performance of the device.

Please visit the following video about how to replace the batteries for the Leak Sensor

 

  • Question: Do you know how high off the ground the sensor prongs are on the bottom of the leak sensors 

Answer:

There is 0.3 millimeter between the water leak sensor prongs and the ground.

 

  • Question: How tall in inches are the sensors? Will they fit under a fridge? 

Answer:

The water leak sensor itself has a 3/4 inch height, it needs 1 inch or more height to operate

 

  • Question: Is this sensor waterproof? What if a water leak floods over the sensor? Will it short out or be damaged?

Answer:

YoLink Water Leak Sensor is designed to be  100% waterproof, but if any set of probes touch the water, it will cause the device to push an alert notification.
Please place the device in the area to be detected, avoid rain, or other alerts that are not caused by water leaks/spills.
And please keep the distance less than 1,000ft between YoLink Hub and YoLink Water Leak Sensors.

 

  • Question: what is the waterproof rating, and can the sensor units withstand a manufacturing environment where they will be exposed to solvent vapors

Answer:

The waterproof rating of YoLink Water Leak Sensor is IP68. It is 100% waterproof, can be used continuously in the water for a long time. It can withstand a manufacturing environment where they will be exposed to solvent vapors.

 

  • Question: I just installed water sensors in 8 locations in the house. How do you recommend testing those?

Answer:

  1. Add the leak sensor to YoLink App and confirm it is online
  2. Use a basin to hold water more than 1mm in height
  3. Put the leak sensor into the basin and check the App push notifications

Note, if you need to test the leak sensor, please complete the test and dry it before placing it in the position to be monitored.

 

  • Question: Regarding your water sensors, I believe they operate on 3 volts DC. Is that correct? 

Answer:

Yes, YoLink Water Leak Sensor operates on 3V DC.

 

  • Question: I recently purchased a YoLink water leak detector system. All works. My hot water heater is in the attic. My question is how does heat affect the sensor in the attic? Today it was 100 degrees.

Answer:

The working temperature of the YoLink Water Leak Sensor is 32°F-122°F. 122°F is the safe temperature. Actually, this sensor can work less than 140°F. So 100 degrees is fine.

 

  • Question: How to exit from alerts?

Answer:

Wipe the probe of the leak sensor dry, then the device will be automatically removed from alerts.

 

  • Question: What is the warranty on this product, if any? 

Answer:

All YoLink battery-powered sensors, including the YoLink Water Leak Sensor, have two years warranty.

 

  • Question: Does it work with Alexa if no YoLink Hub? 

Answer:

Sorry, YoLink Water Leak Sensor does not work with Alexa without YoLink Hub. Because YoLink Hub connects YoLink Water Leak Sensor to the internet and YoLink Cloud. The integration of YoLink Water Leak Sensor with Alexa and IFTTT works through YoLink Cloud. Without the internet, the smart phone notifications and Alexa voice notifications will not work.

But with unique YoLink Control, the YoLink valve controller which is linked to the leak sensors will still work, if the leak sensor detects water, the linked valve controller will turn off the water. YoLink Siren Alarm can be linked with the leak sensors to make a loud sound when any linked leak sensor detects water even when the router is off. 

 

  • Question: will this sensor connect/work with Harmony hub? / Does this work with Vera plus?/ Does it work with Samsung SmartThings?

Answer:

Sorry, YoLink is an independent smart home system. YoLink Hub is the only central controller for the YoLink products. The YoLink Water Leak Sensor will not work with other brands’ hub.
But YoLink Water Leak Sensor works with IFTTT. If you have YoLink Hub and YoLink Water Leak Sensor, you can use YoLink Water Leak Sensor to trigger other brands’ action devices through IFTTT App.

 

  • Question: When pressing set I get red not green. In the app all devices are normal. Are they operational?

Answer:

About the indicator light of YoLink Water Leak Sensor,
There will be a light when you press the SET button of the device (the device is connected to the network/the device is not connected to the network)
1) The device is not connected to the network: press the SET button, the device will blink green
2) The device is connected to the network: press the SET button and see a red light, the device light at this time has no specific meaning, and is used to initially determine whether the device is working normally.

 

  • Question: there are two lights on the front of the sensor and neither is lit. Should a light be on? Seems like that would notify you it was working. But nothing is lit on my sensors.

Answer:

The water leak sensor has 2 indicator lights: an alert indicator on the top and a status indicator on the bottom.
1) Alert indicator light: When the water leak sensor detects water leakage, the red light flashes, and there will be no light in the general monitoring state.
2) Status indicator light: when you press the SET button, the green light will flash (when the device is not connected to the internet) or the red light will flash once (the device is connected to the internet); long press the SET button for 5-10s, the green light flashes, the device is under pairing of YoLink Control; long press the SET button for 10-15s, the red The light flashes, the device is under unpairing of YoLink Control.

 

  • Question: I have an application where I would like to be alerted if the water level gets too high and trips a float sensor that is normally open. Do you have a sensor that I could wire a float switch to?

Answer:

There are 3 ways to connect the extension cable to YoLink Leak Sensor.
1. Soldering with a soldering iron:
(1) Use a soldering iron to solder 2 common wires (regardless of positive or negative) to a set of probes on the Leak Sensor (a set of probes on the top of the leak sensor is recommended)
(2) Fix the leak sensor in one place (If you use double-sided tape to paste the bottom of the leak sensor to the wall, the thickness of the double-sided tape must be higher than the height of the footpad on the bottom of the leak sensor (>1.5mm), otherwise, the leak sensor may not stick firmly)
(3) Place the 2 wires in the area to be detected. The 2 wires must be separated and fixed with a certain distance (10~15mm)
But please kindly note: If you use a soldering iron to solder the wire, it may damage the two probes of the original device, which may cause the probes to rust in a humid environment.

  1. Use glue or tape to fix
    (1) Use glue or tape to stick 2 ordinary wires (regardless of positive or negative) to a set of probes on the leak sensor (a set of probes on the top of the leak sensor is recommended)
    a. Stick the wire to the end of the probe and roll it into a circle or ring to expand the contact area & assist in fixing;
  2. It is recommended to use glue/tape with high viscosity, which must be firmly adhered to!
    (2) Fix the leak sensor in one place (If you use double-sided tape to paste the bottom of the leak sensor to the wall, the thickness of the double-sided tape must be higher than the height of the footpad on the bottom of the leak sensor (>1.5mm), otherwise, the leak sensor may not stick firmly)
    (3) Place the 2 wires in the area to be detected. The 2 wires must be separated and fixed with a certain distance (10~15mm)
    But please kindly note: If the glue/adhesive tape fails to stick the wire firmly, it may cause the wire to fall off and the leak sensor may not work properly.
  3. Use the Alligator Clip
    We have found a way to use the Alligator Clip to clamp securely connecting the probes of the leak sensor and the extension cables, please visit the following video for instruction, https://youtu.be/x-bBXegLUcc
    Please wrap the leak sensor and the clip with tape to prevent it from falling off.
    As for the clip, you will find it on Amazon https://www.amazon.com/dp/B0739YWFQ6

 

  • Question: What are the dimensions of the water sensors? (Inches and centimeters)

Answer:

The dimension of YoLink Water Leak Sensor is 2.44*2.44*0.93inches (62*62*23.5mm), the package dimension is 2.48*2.48*1.02inches (63*63*26mm).

 

  • Question: I have installed 5 sensors and they are bound and visible on the App. Now I’m trying to set up an automated notification trigger but it is instructing me to first set up “behaviors”.

Answer:

The reason why you cannot choose smart automation is that you do not have smart action items.
You can choose your water leak sensor as “IF”, but there is no device that works as “THEN”.
Please watch the following video about how to create automation
YoLink Leak Sensor works with Alexa, you can create routines in Alexa to get voice announcements, and you can check the status for your sensor.
YoLink Leak Sensor works with IFTTT, if you have any other smart action devices, you can use your leak sensor to trigger them.
About how to create routines in Alexa and how to connect to IFTTT, please visit https://youtu.be/rFCbE3pW4f8 on Part 4 – Alexa Integration, Part 5 – IFTTT Integration.

 

  • Question: Depth of water required to trigger alarm?

Answer:

About 0.3 millimeter (a few drops of water) is enough to trigger the sensor.

 

  • Question: Does applying new firmware to the water sensor require that you press the button to apply the update?

Answer:

To update the firmware of YoLink water sensor or other battery-powered YoLink sensor, there is no need to press the setup button. By pressing the set button, the update will start immediately, if you don’t press the set button, the update will not start until the sensor sends a heartbeat (handshake) signal to the cloud through the hub, which takes up to 4 hours.

 

  • Question: Hello, can your water leak sensors be used outdoors in freezing temperatures? I want to install 1 or 2 of these alarms in my septic tank which is located roughly 75 feet from my house. 

Answer:

The water leak sensors can be used outdoors, -30C will be ok. The battery working temperature for YoLink Water Sensor is 32°F – 122°F (0°C – 50°C). Battery capacity will be significantly reduced in low temperatures and may take a risk to be exploded in the high temperature, which will do a great effect on the device. For a wide range of temperatures (out of working temperature), it is recommended to use the AAA lithium battery.

 

  • Question: Is the water leak detection system compatible with the Erro Wi-Fi?

Answer:

YoLink water leak sensor uses a new wireless technology that LoRa communicates with the hub. Only the Hub needs to be connected to the Internet, it can be connected to the router via an Ethernet cable, no Wi-Fi connection is required. If you don’t have a router with an Ethernet port, the YoLink Hub can also connect to the Internet via 2.4G Wi-Fi. All other YoLink devices (including water leak sensors, door sensors, motion sensors, etc.) are connected using the longest distance and lowest power consumption LoRa wireless technology. Therefore, this is the most reliable and reliable connection.

 

  • Question: I noticed that the YoLink Leak Detector provides a temperature value on the detailed App page. What is the purpose of that feature? Can I depend on the Leak Detectors to provide accurate room temperature? What is the temperature range of the Leak Detector readout?

Answer:

As for the temperature value of the leak sensor, it is used to detect the ambient temperature of the water leak sensor.
It cannot be used to detect the temperature value of the room.
