WaterSensor+ is a wireless sensor that detects the presence of water. The sensor also measures temperature and humidity and can warn in case of danger of frost. If water is detected, the sensor sends signals to the Linkbox+ that automatically shut off the water supply. A light and soundalarm is triggered both on the sensor and on the Linkbox+. In addition, users in the Abralife app are notified. The wireless water sensor is small and can be placed freely where the risk of leakage is greatest or where temperature and humidity are desired. The included battery has a lifespan of >5 years.
Watersensor+ can also be placed in a mounting bracket or a dock for concealed cable routing. The brackets make it possible to connect external power supply, as well as sensor tape for additional coverage area.
See the Waterguard+ Installation and User Manual for setup and usage information
WaterSensor+ supports WiMEA, Zigbee and Bluetooth, as well as over-the-air software updates.

WaterSensor+ is a wireless water sensor that communicates with Linkbox+ via WiMEA, a proprietary wireless protocol developed by for safety-critical communications between Linkbox+ and sensors developed by Abra.
Water detection: WaterSensor+ is capable of detecting even small amounts of water, triggering an alarm on Link. This feature is crucial for preventing water damage in your home by providing early warning of leaks from pipes, appliances or other sources.
Temperature measurement: WaterSensor+ continuously measures ambient temperature. This helps you keep track of the temperature conditions in your home and makes it possible to detect the risk of frost damage to water pipes and other installations.
Relative humidity (RH) measurement: WaterSensor+ measures the relative humidity (RH) where the unit is located. This is useful for monitoring the humidity level in your home. By keeping track of humidity, you can identify and address potential moisture-related issues before they escalate.

WaterSensor+ runs the AbraOS operating system, a proprietary Real Time Operating System (RTOS) that runs in real time. The AbraOS operating system is designed for use in security-critical functions, and to be immune to viruses and cyberattacks, providing an extra layer of security for your smart home.
Abra OS automatically updates over-the-air (OTA) if WaterSensor+ is connected to Linkbox+ via WiMEA or from mobile phone over Bluetooth. This ensures that the latest version of the operating system is always installed and that you always have access to the latest features and security enhancements. The update process takes only a few minutes and is completed at times when critical features are not in use.
The Abralife app enables residents to set up, monitor and control their home. With the app, you can, among other things, read the temperature and humidity, open and shut off the water supply, as well as receive push notifications in case of triggered alarm or other error situations - no matter where you are.
The Abralife app displays the connection status, alarm status, temperature and humidity of the WaterSensor+.
The Abralife app is available for Android in Google Play and for iOS in the App Store.
Compatibility and additional equipment
WaterSensor+ is compatible with both Linkbox+ 4G and Linkbox+ WiFi
BILDE OG LINK
WaterSensor+ supports the following communication protocols:
|915 MHz FCC (US/CAN), 868 MHz RED (EU)

Guidelines for choosing the optimal location
WaterSensor+ can be wall-mounted using included brackets. Alternatively, the product can lie flat on a suitable surface without the use of fixing brackets.
- Reduce disruption: Keep WaterSensor+ away from electronic devices that might interfere with signals, such as microwave ovens or cordless phones. We recommend > 1 m distance to mentioned or similar equipment that transmits or receives high-frequency radio signals.
Check signal strength: Look for locations with good cellular signal strength to ensure reliable 4G connectivity.
WaterSensor+ standalone installation
Place WaterSensor+ in locations where there is a risk of water leaks.
This is typically behind a washing machine, in kitchen cabinets or behind a dishwasher.

Use of the product
Pairing device to WaterSensor+
Click here for guidance on how to add devices via the Abralife app.
To connect wireless devices using the button on the front of the Linkbox+, follow the procedure below, or as described in this article.
- The Linkbox+ must be connected to power before the procedure is carried out.
- The signal strength is often weaker during interconnection than in normal operation. It is therefore recommended that wireless devices are near the Linkbox+ during connection (before being deployed in the home).
Briefly press (<1 second) the Linkbox+ button to activate connection mode. Connection mode is indicated by the status symbol on the Linkbox+ pulsing with BLUE light.
Enable connection mode on the wireless device to be connected to the Linkbox+. Follow the instructions in the Abralife app or the manufacturer's instructions. If you are unsure whether your device is supported by Abra, we recommend following the instructions for using the Abralife app.
Press and hold the button on that WaterSensor+ for > 1 second to initiate automatic connection to the Linkbox+. The droplet symbol of the sensor blinks rapidly BLUE. The devices will now connect.
3. Successful pairing is indicated by 3x beep and 3x GREEN flashes in the status LED. Repeat the procedure for each new device to be paired.
NB! Do not apply large amounts of water to the sensor when it is held upside down. The sealing mechanism requires the sensor probes to point downwards.
- Open a water tap and let the water run (e.g. kitchen sink)
With a wet cloth, etc., moisten the sensor points on the wireless sensor:
- If the sensor is mounted in a bracket with sensor tape, one of the sensor points on the connected sensor tape is moistened.
- If the sensor is mounted in a bracket without sensor tape, one of the two pairs of sensor probes is moistened on the back of the bracket
If the sensor is placed loosely without a bracket, one of the two pairs of sensor probes is wetted on the underside of the sensor (see picture below)
- The valve(s) close automatically
- The water stops flowing
- Linkbox+ emits audio signal
- The water drop symbol on Linkbox+ glows red
- The current wireless sensor emits an audible signal
- The water drop symbol on the current wireless sensor flashes red
