ECOWITT WH57 Wireless Lightning Detection Sensor User Manual

1. Product Overview

The ECOWITT WH57 Wireless Lightning Detection Sensor is designed to detect lightning bolts and storms within a 25-mile (40-kilometer) radius. This sensor is an accessory and requires a compatible gateway (such as the GW1100, sold separately) for operation and data transmission. Once connected, data can be viewed via the WS View Plus or Ecowitt App, and historical records are available on the Ecowitt Weather Server.

Key Features:

• Detects lightning bolts and storms within 25 miles (40 kilometers).
• Requires a GW1100 WiFi gateway (sold separately) for connectivity.
• Live data viewing on WS View Plus or Ecowitt App.
• Graph and history records available on the Ecowitt Weather Server (ecowitt.net).
• Email alert functionality from the Ecowitt Weather Server.
• Includes a solar radiation shield and mounting arm.

2. Setup and Installation

2.1 Unpacking and Battery Installation

Carefully unpack all components. The WH57 sensor requires 2x AA batteries (not included). To install batteries:

1. Open the battery compartment cover on the back of the sensor.
2. Insert 2x AA batteries, ensuring correct polarity (+/-).
3. Close the battery compartment cover securely.

2.2 Dip Switch Configuration

The WH57 sensor features four dip switches inside the battery compartment for configuration. These switches control the sensor's operating mode, antenna type, and sensitivity.

Refer to the diagram above and the table below for proper configuration:

Note: Ensure the dip switches are set according to your intended use and desired sensitivity before closing the battery compartment.

2.3 Mounting the Sensor

The WH57 sensor comes with a solar radiation shield and a mounting arm for pole installation. Choose an outdoor location that provides clear exposure to the environment and is away from large metal objects that could interfere with detection.

Mounting Steps:

1. Assemble the solar radiation shield and mounting arm as shown in the diagram.
2. Attach the WH57 sensor securely to the assembled unit.
3. Mount the entire assembly onto a pole using the provided hardware. Ensure it is stable and level.

2.4 Pairing with a Gateway

The WH57 sensor cannot operate independently. It must be paired with a compatible ECOWITT WiFi gateway (e.g., GW1100, GW2000) or a display console (e.g., HP2551, HP2553, HP3500, WN1900, WN1910 weather station) to transmit data.

Pairing Process:

• Ensure your gateway is powered on and connected to your Wi-Fi network.
• The WH57 sensor will automatically attempt to connect to the nearest compatible gateway upon battery installation.
• Verify successful connection through your gateway's interface or the WS View Plus/Ecowitt App.

For detailed gateway setup and Wi-Fi configuration, please refer to your specific gateway's instruction manual.

3. Operation

Once successfully set up and paired, the WH57 sensor will continuously monitor for lightning activity. Data is transmitted wirelessly to your gateway and then uploaded to the Ecowitt Weather Server.

3.1 Viewing Live Data

Live lightning strike data, including the number of strikes daily and the time and distance of the last strike, can be viewed on the WS View Plus or Ecowitt App. Ensure your phone is connected to the same Wi-Fi network as your gateway for live data access.

3.2 Accessing History and Graphs

For historical records and graphical representations of lightning activity, visit the Ecowitt Weather Server at ecowitt.net. You can log in to your account to view detailed data and download records. It is recommended to create a shortcut to the website on your phone or computer for quick access.

3.3 Email Alerts

Configure email alerts through the Ecowitt Weather Server to receive notifications when lightning activity is detected. This feature allows for remote monitoring and timely awareness of storm conditions.

4. Maintenance

4.1 Battery Replacement

The WH57 sensor is battery-powered. Monitor the battery level display on the WS View Plus App or the Ecowitt Weather Server. Replace batteries promptly when the low battery alert is triggered to ensure continuous operation. Refer to Section 2.1 for battery installation instructions.

4.2 Cleaning

Periodically inspect the sensor and solar radiation shield for dirt, dust, or debris. Gently clean the exterior surfaces with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the unit.

4.3 Environmental Considerations

While the sensor is designed for outdoor use and is IP44 waterproof, extreme weather conditions (e.g., heavy snow, ice, prolonged direct sunlight in very hot climates) may affect its performance or lifespan. Ensure the mounting location is secure and stable, especially during high winds.

5. Troubleshooting

• No Lightning Data Displayed:
  
  • Ensure the WH57 sensor has fresh batteries and is powered on.
  • Verify that the sensor is successfully paired with your ECOWITT gateway. Check the gateway's status or app for sensor connectivity.
  • Confirm your gateway is connected to your Wi-Fi network and has internet access.
  • Check the distance between the sensor and the gateway; ensure it is within the effective wireless range (up to 100m/300ft line of sight).
• Inaccurate or Unexpected Readings:
  
  • Review the dip switch settings (Section 2.2) to ensure they match your installation (Indoor/Outdoor, Antenna type) and desired sensitivity.
  • Ensure the sensor is mounted in an optimal location, away from large metal structures or electrical interference.
  • Adjust the sensitivity settings via the dip switches if you are experiencing too many false positives or missed detections.
• Sensor Not Connecting to App/Server:
  
  • Confirm your gateway is online and registered with the Ecowitt Weather Server.
  • For live data on the app, ensure your mobile device is on the same local Wi-Fi network as the gateway.
  • For remote access, ensure your gateway has a stable internet connection.
