Follow these steps to set up your Meross Smart Water Sensor Alarm System.

4.1. Download the Meross App

Søg efter "Meross" in the Apple App Store or Google Play Store and download the application. Register for a new account or log in with an existing one.

4.2. Power On the Meross Hub

Plug the Meross Hub into a power outlet. Ensure it is within range of your 2.4GHz Wi-Fi network. The hub's LED indicator will flash, indicating it is ready for pairing.

4.3. Add the Hub to the Meross App

1. Open the Meross app.
2. Tryk på "+"-ikonet i øverste højre hjørne for at tilføje en ny enhed.
3. Select "Hub" from the device list and follow the on-screen instructions to connect it to your 2.4GHz Wi-Fi network.

4.4. Add Water Sensors

Once the hub is successfully added, you can add the water sensors:

1. In the Meross app, select your newly added hub.
2. Follow the prompts to add a new sensor. The app will guide you through the process, which typically involves activating the sensor (e.g., by pressing a button or wetting the probes briefly).
3. Repeat for all three sensors. It is recommended to rename each sensor immediately (e.g., "Kitchen Sensor," "Basement Sensor") for easy identification.

4.5. Integrate with Smart Home Platforms (Optional)

The Meross system supports Apple HomeKit and SmartThings. To integrate:

• Apple HomeKit: Ensure your Meross Hub is HomeKit compatible. Open the Apple Home app, tap the "+" icon, and select "Add Accessory." Scan the HomeKit code on your Meross Hub or its packaging. A home hub (HomePod, HomePod mini, Apple TV, or iPad) is required for remote control and automation. For more details, refer to Apple's HomeKit support page.
• SmartThings: Follow the instructions within the SmartThings app to add Meross devices.

4.6. Sensorplacering

Place the water sensors in areas prone to leaks. The sensitive probes detect water levels as low as 0.5mm. Common locations include:

• Nær vandvarmere
• Under vaske (køkken, badeværelse)
• Next to washing machines or dishwashers
• I kældre eller bryggerser
• Near toilets or bathtubs
• Under fish tanks

5.1. Leak Detection and Alerts

When a water leak is detected by a sensor, the system will:

• Trigger a local audible alarm (69 dB) from the sensor.
• Send instant push notifications to your smartphone via the Meross app and integrated smart home platforms (HomeKit, SmartThings).
• The Meross app will display the status of the sensor as "Water leak detected."

5.2. Fjernovervågning

Monitor the status of your water sensors from anywhere using the Meross app on your smartphone. This allows you to check for leaks even when you are away from home.

5.3. Automation Features

Utilize the Meross app to create automation rules. For example, you can set a trigger so that if a leak is detected, a Meross smart plug connected to a water pump automatically turns off, preventing further damage.

6. Vedligeholdelse

6.1. Udskiftning af batteri

Each Meross water sensor is powered by one CR123A battery, providing up to 18 months of life. The Meross app will notify you when a battery is low. To replace:

1. Gently twist the top cover of the sensor counter-clockwise to open it.
2. Fjern det gamle CR123A-batteri.
3. Isæt et nyt CR123A-batteri, og sørg for at polariteten vender korrekt.
4. Align the top cover and twist clockwise to secure it.

6.2. Rensning

Wipe the exterior of the sensors with a soft, damp cloth as needed. Do not use harsh chemicals or abrasive cleaners. Ensure the metal probes at the bottom are clean and free of debris for optimal detection.

6.3. Vandtæthedsklassificering

The sensors feature an IP67 waterproof and dustproof design, ensuring stable operation in high humidity environments. This rating means the sensor is protected from dust and can withstand immersion in water up to 1 meter for 30 minutes. However, to prolong battery life and prevent potential issues, avoid prolonged soaking in water.

7. Fejlfinding

If you encounter issues with your Meross Smart Water Sensor Alarm System, refer to the following common solutions:

• Sensor Not Connecting to Hub:
  • Ensure the sensor is within the 100m/328ft range of the hub. Walls and obstacles can reduce this range.
  • Check the sensor's battery level in the Meross app. Replace if low.
  • Try re-pairing the sensor with the hub through the Meross app.
• Hub opretter ikke forbindelse til Wi-Fi:
  • Verify your Wi-Fi network is 2.4GHz. The Meross Hub does not support 5GHz Wi-Fi.
  • Ensure the hub is within good range of your Wi-Fi router.
  • Restart your Wi-Fi router and the Meross Hub.
  • Check your Wi-Fi password for accuracy during setup.
• Falske alarmer:
  • Ensure the sensor probes are clean and dry. Dust or condensation can sometimes trigger false alarms.
  • Relocate the sensor if it's in an area prone to condensation or minor splashes that are not actual leaks.
• Ingen app-notifikationer:
  • Check your smartphone's notification settings for the Meross app and ensure they are enabled.
  • Bekræft, at din telefon har en aktiv internetforbindelse.
  • Ensure the Meross Hub is connected to your Wi-Fi and online.
• HomeKit/SmartThings Integration Issues:
  • Ensure your home hub (for HomeKit) is online and functioning correctly.
  • Follow the specific integration steps carefully within the respective smart home app.
  • If issues persist, try removing and re-adding the Meross Hub from the smart home platform.
