Your Water Leak Sensor 2 connects to the internet via a YoLink hub (SpeakerHub or the original YoLink Hub), and it does not connect directly to your WiFi or local network. In order for remote access to the device from the app, and for full functionality, a hub is required. This guide assumes the YoLink app has been installed on your smartphone, and a YoLink hub is installed and online (or your location, apartment, condo, etcetera, isalready served by a YoLink wireless network).

Installation
Location considerations:
Before installing your Water Leak Sensor 2, consider the following important
factors:
- This device is intended for indoor use, only. The sensor body should not be installed where it will normally get wet or be submerged.
- Additional cables can be added to extend the length of the water detection cable and/or to expand the detection region (to cover a larger area). The total length of the final arrangement of cables must not exceed 30 feet or 9 meters.
- The Water Leak Sensor 2 has an integral sounder alarm. Its use is optional, as it can be enabled or disabled, in the app settings. Please note, using this sounder as your primary means of notification is discouraged, as various factors, such as the distance from where you are to this sensor, the number of doors, walls or floors that may be between the sensor and you, if you are asleep, etcetera, can all reduce the chance you will hear the alarm. If a siren alarm is preferred, please consider one of our siren products and our SpeakerHubs (audio, tone and message-playing, hubs). Also, please note, the use of the sounder does reduce the maximum life of the batteries.
- The Water Leak Sensor 2 is typically mounted on the wall or on a stable vertical surface, near the floor.
- While the sensing cable(s) can be placed in a confined space, such as behind a refrigerator, the sensor should be placed in an accessible location (for example, to allow for easy battery replacement later).
Determine the sensor location and approximate cable placement:
- Connect the cable to the sensor, by plugging the male end of the cable into the sensor. If you are using additional cables, connect them at this time.
- The applications for the Water Leak Sensor 2 are numerous and this quick start guide can not address all of them in detail. But the sensing cable(s) will typically be placed so that they encircle the region where a water leak may occur. Some common examples are placing the cable around the base of a toilet, or around the inside perimeter of a bathroom vanity with sink, around a laundry washing machine or water heater. In addition to placing the cable to surround an area, snaking the cable back and forth across a region may provide better coverage, resulting in a faster response time.
- If you still are unsure how to place the cable, or whether or not you need additional cables, you can test the location by simulating a water leak. For example, pour a small amount of water on the area where you expect a water leak may occur. Observe how the water pools or expands over the area. Consider the slope of the floor, which may be prominent in basement or mechanical spaces that have a floor drain (generally, all points on the floor will slope down to the drain). Try to place the cable so that it is in the path of pooling or moving water.
- Lay the cable(s) on the floor, as required for your application, temporarily, at this time, so that you can determine the appropriate location for the sensor.
Install the mounting hook:
- After the location and placement of the cable(s) has been determined, define the location of the sensor. The mounting hook should be installed at this location. (If you intend to mount the Water Leak Sensor 2 using another method, such as double-sided mounting tape or Velco, do so at this time, per the manufacturer’s instructions.)
- Clean the surface where the mounting hook will be placed, using rubbing alcohol (recommended) or a degreaser that does not leave a residue on the surface. In order for the pre-installed mounting tape to adhere to the surface, the surface must be clean, dry and free of dirt, oils, grease, or other cleaning agent residue.
- Remove the plastic backing from the mounting tape on the mounting hook.
- With the hook facing up, as shown, press it firmly against the mounting surface and maintain pressure for at least 5 seconds.
Install and test the Water Leak Sensor 2:
-
Hang the sensor on the mounting hook, using the slot on the back of the sensor. Ensure it is secure, by gently tugging on it.
-
It is important that you test each sensor, to ensure it will work properly when needed! Please note, before testing, if the sensing cable is emersed in water, it can take an extended period to dry. You can perform a “functional test” of the leak sensor by pouring water in the detection area, but we aware of the extended drying time. One testing method is to use a paper towel or cloth that is slightly damp with water. Place this gently on the sensing cable, allowing it several seconds to respond. The sounder should ctivate and the LED should flash red.
Spare cables can be purchased, allowing for a quick replacement after a water leak event! -
Unplug the sensing cable and allow it time to dry, or actively dry it with a heat source like a hairdryer. Reinsert the cable until it no longer causes a leak alert response response.
