Your Water Leak Sensor 4 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, is already served by a YoLink wireless network).

Install the Water Leak Sensor 4

Sensor location considerations:

Before placing and setting up your Water Leak Sensor 4, consider the following important factors:

The Water Leak Sensor 4 is intended for indoor use, only. It should only be used in indoor environments and within he temperature and humidity ranges as speciﬁed in the product listing and product support page on our website.
While the Water Leak Sensor 4 is waterproof, it should not be used where it will always be in water or where it may frequently be submerged in water. If water level monitoring is required, consider our Water Level Monitoring Sensor.
The Water Leak Sensor 4 has water-sensitive probes or electrodes on both the top and bottom. When water is on or touches any pair of electrodes, this creates an electrical “short circuit” between the electrodes, and the sensor responds with a water leak alert. The top of the sensor is identiﬁed by a cupped area with one pair of electrodes. This cupped area is ideal for catching dripping water from above, such as under a sink. The bottom of the sensor has two pairs of electrodes. These are optimized for detecting water that pools or floods below the sensor.
Applications for the Water Leak Sensor 4 are many, and they can not be covered in detail in this quick start guide.
If you are unsure where to place your Water Leak Sensor 4, please contact us.
When determining the location and quantity of sensors required for your applications, consider the types of leaks or flooding that is expected. For example is the water coming from water overflowing, like a sink, toilet, or tub? Is it coming from a leak within an appliance, like a dishwasher? Is it coming from a loose or broken plumbing ﬁtting, like on a laundry machine or ice maker water line? Generally, every location where water goes into or leaves an appliance, where there is a ﬁtting or connection between two pipes, or ﬁxtures, between a hose and a hose connection, and at every faucet or ﬁxture where water comes out, is a potential leak location.
Consider how water may flow and pool or collect if there is a leak at each possible leak location. Consider the slope of the floor or the surface that water may drip onto. A leak at a sink cleanout will result in water directly below the sink, and this water may run towards the front of the vanity or cabinetry or to the back, draining into the base of the cabinetry (only appearing on the floor after a signiﬁcant leak has occurred). Floors with drains, like in a mechanical room or near a water heater, are intentionally sloped down to the drain. Floors in older homes or where settling has occurred can also result in a slope. Take advantage of any slope in the floor by placing the leak sensor at the bottom of the slope or in the path of the water flowing down the slope. A marble, toy ball, or similar object can be used to check the floor’s level, or you may consider pouring a small amount of water on the floor or surface where a leak is possible, to see how the water may flow and pool up.
Additional leak sensors can be added if you wish to protect a large region, or you can consider the Water Leak Sensor 2, our rope style leak sensor, that allows for creating larger water detection regions, with the use of additional cables.
Avoid locations where the sensor may be moved or disturbed by people or pets.
Avoid locations in trafﬁc areas where it may be kicked or stepped on, etc.

Place the leak sensor
After you have selected a location for the leak sensor, simply place it on the floor or surface, with the cupped part of the sensor facing up.
Test the leak sensor
Functionally test each sensor. A common way to test the Water Leak ensor 4 is by touching any pair of electrodes with a damp paper towel, but you may ﬁnd that you can activate the sensor by bridging a pair of electrodes with your thumb or ﬁnger. If you choose
to pour water on the sensor or on the floor, be sure to fully dry off the sensor after testing. With the app in hand, and the particular leak sensor in view in the app, test your Water Leak Sensor 4. After the sensor has responded properly (and you’ve dried it off, if applicable), conﬁrm the sensor is shown to be “Normal” in the app.
Refer to the full Installation & User Guide and/or the product support page and online support resources to complete the setup of your Water Leak Sensor 4, including use of the YoLink app, automations (such as automatic water shut- off and siren activation) and to conﬁgure your notiﬁcation preferences (such as phone push notiﬁcations, emails, SMS/text messages).
