- Отворите апликацију и направите нови налог или се пријавите ако га већ имате.
3.2. Hub Setup
- Connect the YoLink Hub to power using the provided USB cable and power adapter.
- Connect the Hub to your internet router using the provided Ethernet cable. Ensure the internet indicator light on the Hub turns solid blue.
- In the YoLink App, tap the "+" icon or "Add Device" to add the Hub. The app should automatically detect the Hub. Follow the on-screen prompts to complete the setup.
3.3. Leak Sensor 4 Setup
- Ensure the AAA batteries are correctly installed in each Leak Sensor 4.
- In the YoLink App, tap the "+" icon or "Add Device".
- Scan the QR code located on the back of each Leak Sensor 4.
- Follow the app's instructions to name each sensor and assign it to a specific room or location (e.g., "Kitchen Sink", "Water Heater", "Laundry Room"). This helps in identifying the leak source quickly.

3.4. Почетно тестирање
After setting up each sensor, it is recommended to perform an initial test:
- Place a small amount of water (e.g., a damp paper towel) on the two metal prongs located on the bottom of the Leak Sensor 4.
- The sensor should emit a 105 dB audible alarm, and you should receive an alert notification on your YoLink App, email, and/or SMS/text message.
- Remove the water to silence the alarm.

4. Упутство за употребу
4.1. Постављање сензора
Strategically place your Leak Sensor 4 units in areas prone to water leaks, such as:
- Under sinks (kitchen, bathroom)
- Near water heaters
- Behind toilets
- Near washing machines or dishwashers
- In basements or utility rooms
- Близу фрижидера са апаратима за лед
Ensure the metal prongs on the bottom of the sensor are in direct contact with the surface where water might accumulate. The sensor can also detect drips from above if water collects on its top surface.
