3. Setup and Pairing
The Centralite Water Sensor features a "pull-to-pair" mechanism for easy integration with your Zigbee HA 1.2 certified smart home hub.
- Prepare the Sensor: The CR2 battery is pre-installed. To activate the sensor and begin the pairing process, gently pull out the small plastic tab located at the bottom of the device.
- Initiate Pairing on Your Hub: Put your Zigbee HA 1.2 compatible smart home hub (e.g., SmartThings, Hubitat, Ezlo, Vera, Alexa) into pairing mode. Refer to your hub's specific instructions for this step.
- Confirm Pairing: Once the plastic tab is removed, the sensor will automatically attempt to pair. Follow the prompts on your smart home hub's application to complete the pairing process. A successful connection is typically indicated by a light on the sensor or a notification in your hub's app.

4. Placement and Installation
Proper placement is crucial for effective leak detection. The sensor should be placed directly on the ground in areas prone to water leaks.
- Recommended Locations: Near water heaters, under sinks, next to washing machines, dishwashers, refrigerators with ice makers, toilets, and in basements.
- Surface Type: Place the sensor on any non-conductive surface such as granite, glass, brick, or tile. The conductors on the underside of the sensor must make direct contact with any pooling water.

5. Operation
Once installed and paired, the Centralite Water Sensor continuously monitors for the presence of water. When water is detected, the sensor will send an alert to your connected smart home hub, which can then trigger notifications on your smartphone or other configured actions.
- Detection: The sensor uses capacitance detection to identify water on its contact points. It can detect as little as 0.5 ounces of water.
- Notifications: Configure alerts through your smart home hub's application to receive immediate notifications when a leak is detected.
- Compatibility: The sensor is fully Zigbee HA 1.2 certified, ensuring compatibility with a wide range of smart home ecosystems including SmartThings, Hubitat, Ezlo, Vera, and Alexa.

6. Maintenance
Battery Replacement
The Centralite Water Sensor uses one CR2 Lithium battery, which provides up to 2 years of life under normal usage conditions. When the battery level is low, your smart home hub will typically send a notification.
- Gently open the sensor casing to access the battery compartment.
- Remove the old CR2 battery.
- Insert a new CR2 Lithium battery, ensuring correct polarity.
- Close the sensor casing securely.
Cleaning
Wipe the sensor's exterior with a soft, dry cloth. Do not use liquid cleaners or immerse the device in water.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Sensor not pairing | Plastic tab not removed; hub not in pairing mode; sensor too far from hub; low battery. | Ensure plastic tab is removed. Put hub in pairing mode. Move sensor closer to hub. Replace battery if necessary. |
| No leak detection alerts | Sensor not placed correctly; battery low; hub communication issue; notification settings incorrect. | Verify sensor contact points are on the ground. Check battery. Confirm sensor is connected to hub. Adjust notification settings in your smart home app. |
| "Device unresponsive" message | Weak Zigbee signal; low battery. | Move sensor closer to the hub or a Zigbee repeater. Replace battery. Try re-pairing the device. |
