Setup
1. Base Station Setup
- Power Connection: Connect the included AC adapter to the base station and plug it into a power outlet. For backup power, insert one CR2032 battery (not included) into the designated compartment.
- Initial Display: The display will light up, and the station will begin searching for the outdoor sensor and attempting to connect to Wi-Fi.
- Wi-Fi Configuration: Download the WSLink app on your smartphone or tablet. Follow the in-app instructions to connect your base station to your home Wi-Fi network. This enables access to online weather data, 14-day forecasts, and data sharing platforms like ProWeatherLive and Weathercloud.
2. 8-in-1 Outdoor Sensor Setup
- Battery Installation: The 8-in-1 sensor is primarily solar-powered. For initial setup and during periods of low sunlight, insert three AA batteries (not included) into the sensor's battery compartment. Ensure correct polarity.
- Mounting Location: Choose an outdoor location that is open and unobstructed to ensure accurate readings for wind, rain, and sunlight. The sensor has an impressive range of up to 150 meters from the base station.
- Orientation: Mount the sensor securely using the provided hardware. Ensure the solar panel is oriented towards the sun for optimal charging. The wind vane should be able to rotate freely.
- Sensor Pairing: The base station should automatically detect and pair with the 8-in-1 sensor once both are powered on. If pairing fails, refer to the troubleshooting section.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No outdoor sensor data on display | Sensor batteries low or dead; sensor out of range; interference; sensor not paired. | Replace sensor batteries. Move sensor closer to base station. Check for obstructions. Re-pair sensor (refer to manual for specific steps if auto-pairing fails). |
| Wi-Fi connection failure | Incorrect Wi-Fi password; router too far; network issues; WSLink app not configured correctly. | Verify Wi-Fi password. Move base station closer to router. Restart router. Use WSLink app to reconfigure Wi-Fi settings. |
| Inaccurate temperature/humidity readings | Sensor exposed to direct sunlight/heat source; sensor blocked; calibration needed. | Relocate sensor to a shaded, well-ventilated area. Ensure no obstructions. Use WSLink app for calibration if available. |
| Rain gauge not registering rain | Rain collector blocked by debris; tipping bucket mechanism stuck. | Clean the rain collector funnel and check the tipping bucket for obstructions. |
| Wind speed/direction inaccurate | Wind cups/vane obstructed; sensor not level. | Ensure wind cups and vane rotate freely. Check that the sensor is mounted level. |
