The Neos Smart Leak Sensor detects direct contact with moisture and will notify you via your Neos Smarthome app and audiblly through the devices alarm/sounder. The device also has built-in humidity and temperature monitoring sensors and send will notifications changes in humidity or temperature are detected within the home.

This product is battery powered and works via the Neos SmartCam (Your Neos Smart Bridge plugging into your Neos SmartCam). The device is a great way to detect early leaks from your household utilities, water tanks, boilers and other facilities, providing valuable time to mitigate larger issues in your home.

Unlike motion events, your Neos Smarthome app will notify you at anytime (if the app is armed or not) if your Neos Smart Leak device detects moisture/water.

The device will also notify you via the app if it detects a rise or fall in temperature or humidity outside the ranges you set in-app.

All device notifications can be controlled within the device settings, along with viewing signal strength in the position you have placed the device and monitoring battery life.

The Neos Smart Leak Senor Kit is sold with the following:

•   3 x Neos Smart Leak Sensors (with batteries)
•   1 x Neos Smart Bridge
•   1 x Instruction manual

Please note you will require a Neos SmartCam to operate these devices. This includes a Neos Smart Bridge that attaches to your Neos SmartCam to allow you to add your Smart Leak Sensors to your home WiFi via the camera. If you already have an installed Smart Bridge on your SmartCam, you do not need to use the additional Smart Bridge included in the pack (you can keep this as spare) or add to a second SmartCam (if you have one) and attach the devices closer to it for enhanced connection.

Your Neos Smart Leak Sensor is easily installed via your Neos SmartCam (with Smart Bridge) via the Neos Smarthome app.

Once you have installed the SmartCam, click the + button to view all other available products. Click on the Neos Smart Leak Sensor Icon to start installation. If you have not already installed the Smart Bridge provided in the package, the app will prompt you to do so at this point and walk you through installation.

Follow the on-screen instructions to complete the quick installation. Please note, the casing can be a little stiff to unlock (we want to keep it water tight), please locate a firm flat item like a straight edge screwdriver and carefully prize loose.

Once installed you may get an immediate notification, this is normal as the sensor has picked up moisture from your hand during the setup process. Gently wipe it down and place it into position so ready for the real deal.

The Neos Smarthome app will display all connected devices on its dashboard (opening screen). This screen will give a live update of the current status of the device, including if it's in contact with moisture, low battery or offline. To test the device in real life, place the sensor onto a damp tissue and watch the app update and the device start to sound.

The light on your Neos Smart Leak Sensor has two purposes:

1)   It will flash during device installation to show the product is in setup mode ready to be connected to the SmartCam (via the Smart Bridge)
2)  It will also flash when the sensor comes in contact with moisture/water to provide a visual alert (as well as the device sounder for an Audio- Alarm)

The Neos Smart Leak Sensor is small and discreet so it can be placed next to or near to any source of water in your home as long as it is in range of your Neos SmartCam (and Smart Bridge). Typically, users place these devices under their kitchen utilities, washing machines, bathtubs and shower trays and other sources of leaks such as water tanks, toilets and/or basins.

Once connected to the SmartCam (via the Smart Bridge) the range is up to 45 meters. There are variables that can impact connectivity to your Neos Smart Leak Sensor which may restrict overall range. Once connected, the device will display the signal strenght to allow you to see how strong the connection is between the SmartCam and your device in the selected location.

If you cannot place your Smart Leak Sensor in your desired location due to range, you have two options to solve this issue:

1)   Move your Neos SmartCam (with Smart Bridge) closer to the Smart Leak Sensor location
2)  If you have a second SmartCam (or purchase a second SmartCam), add another Smart Bridge to the device and add the Smart Leak Sensor to the second SmartCam

A Humidity Sensor (or hygrometer) senses, measures and reports both moisture and air temperature. The ratio of moisture in the air to the highest amount of moisture at a particular air temperature is called relative humidity. Relative humidity becomes an important factor when looking for comfort within your household and at more extreme readings, can be an indicator of excess or lack of moisture in the air that can be problematic if left for long periods of time.

When you first install your Smart Leak Sensor, the Smarthome app will set both your humidity and temperature to a default range. The range for humidity is 25% - 50% and 1 dc - 18 dc for temperature. Once the device is installed, you can click on the device in the dashboard, and amend the range to suit your needs via the device settings.
