3. Operating Instructions
3.1 Water Detection
The HEIMAN Water Leak Detector is equipped with two bottom-mounted leak sensor probes that can detect water levels as low as 0.01 inches (0.22mm). When water is detected, the device will trigger an alarm.
The water leak detector is designed to detect water from both small leaks and larger floods, indicated by the water drop icon.
The detector features extra sensitive probes at its base, ensuring quick and accurate detection of even minimal water presence.
3.2 Alarm and Notifications
Upon detecting water, the device will emit a loud 75 dB audible alarm and a blue flashing reminder light. Simultaneously, if connected to Wi-Fi, you will receive real-time notifications on your smartphone via the Tuya/Smart Life APP.

The app features include the ability to notify friends and family, and a 'Smart Hush' function to prevent false alarms when you are connected to the same Wi-Fi network as the alarm.
4. Maintenance
The HEIMAN Water Leak Detector is designed for long-lasting performance. The included CR123A battery can sustain normal usage for up to 5 years. The sensors have a lifespan of up to 10 years. The device is built with IP67 waterproof technology and UV-resistant materials, making it durable in humid and dusty environments.
4.1 Cleaning
To maintain optimal performance, periodically wipe the device clean with a dry cloth. Avoid using abrasive cleaners or submerging the entire device in water, despite its waterproof rating, to protect internal components.
The HEIMAN Water Leak Detector boasts an IP67 waterproof rating, indicating its ability to withstand immersion in water.

4.2 Battery Replacement
When the battery is low, the device will typically indicate this through the app. Replace the CR123A battery by rotating the upper cover to open the device and inserting a new battery, ensuring correct polarity.
5. Troubleshooting
5.1 Connectivity Issues
- Device Offline: Ensure your Wi-Fi network is active and the device is within range. The detector only supports 2.4GHz Wi-Fi.
- Failed Pairing: Double-check your Wi-Fi password. Make sure your phone is connected to the 2.4GHz band during setup. Try resetting the device by long-pressing the networking button until the indicator flashes rapidly, then attempt pairing again.
5.2 Alarm Not Sounding/Notifications Not Received
- No Audible Alarm: Verify the device has sufficient battery power. Ensure the sensor probes at the bottom are making proper contact with the surface where water might accumulate.
- No App Notifications: Check your phone's notification settings for the Tuya/Smart Life APP to ensure notifications are enabled. Confirm the device is online in the app.
5.3 False Alarms
- Environmental Factors: High humidity or condensation might occasionally trigger the sensor. Ensure the placement area is not excessively damp without actual leaks.
- Sensor Contact: Ensure the sensor probes are clean and free from debris that might bridge the contacts.
