Solar Powered: Equipped with a solar panel for primary power, extending battery life.
Backup Battery: Uses 2 x 1.5V AA batteries as a backup power source.
Wide Range: Measures wind speeds from 0 to 178 km/h.
Long Range Transmission: Up to 100 meters in open field conditions.
TFA.me Compatibility: Integrates seamlessly with TFA.me WLAN systems for online data monitoring and historical graphing.

Setup

1. Battery Installation

Locate the battery compartment on the wind transmitter.
Ensure the pre-installed 18650 Li-Ion battery is properly seated. This battery is charged by the solar panel.
Insert the 2 x 1.5V AA backup batteries, observing the correct polarity (+/-). These batteries provide power when solar charging is insufficient.
Close the battery compartment securely to protect against moisture.

2. Mounting the Wind Transmitter

Proper placement is crucial for accurate readings. The wind transmitter should be mounted in an open area, free from obstructions that could interfere with wind flow.

Location: Choose a location that is as high as possible and clear of buildings, trees, or other structures that could block wind or create turbulence.
Orientation: Mount the transmitter horizontally with the solar panel facing directly south. This ensures optimal solar charging throughout the day.
Attachment: Use the provided mounting arm and hardware to securely attach the transmitter to a mast or suitable pole.

3. Connecting to TFA.me System

The wind transmitter is designed to work with specific TFA.me radio stations. Refer to your TFA.me weather station's manual for detailed instructions on how to add a new sensor.

Ensure your TFA.me weather station is powered on and within range (up to 100m line of sight) of the wind transmitter.
Follow the pairing procedure outlined in your TFA.me station's manual to establish a connection.
Compatible TFA.me stations include models such as 35.8100.54, 35.8101.54, 35.8102.01, 35.8103.02, 35.8106.01, 35.8110.02, 35.8109.02, 35.8111.02, 35.8107.01, and 35.8108.02. The article reference number can usually be found on the back of your device.

Operating

Once successfully set up and connected to your TFA.me weather station, the wind transmitter will continuously measure and transmit wind data.

Data Transmission: Wind speed and direction data are sent wirelessly to your TFA.me station at regular intervals.
Online Monitoring: Access real-time and historical wind data through the TFA.me portal on your smartphone, tablet, or computer. The portal provides graphical representations of historical data.
Power Management: The integrated solar panel charges the Li-Ion battery during daylight hours. The AA backup batteries provide power during periods of low light or insufficient solar charging.

Maintenance

Cleaning: Periodically inspect and clean the wind cups, wind vane, and solar panel. Dust, dirt, or debris can affect accuracy and solar charging efficiency. Use a soft, damp cloth for cleaning. Do not use abrasive cleaners.
Battery Check: The TFA.me system will typically indicate the battery status of connected sensors. Replace the AA backup batteries when they are low to ensure uninterrupted operation.
Inspection: Regularly check the mounting arm and hardware for tightness and signs of wear or damage, especially after strong winds.

Troubleshooting

Problem	Possible Cause	Solution
No wind data displayed on TFA.me station.	Transmitter out of range. Low or depleted batteries. Not properly paired with TFA.me station. Obstruction blocking signal.	Move transmitter closer to the TFA.me station (within 100m line of sight). Check and replace AA backup batteries if needed. Ensure solar panel is clean and exposed to sunlight. Refer to your TFA.me station manual for pairing instructions. Ensure clear line of sight between transmitter and station.
Inaccurate wind speed or direction readings.	Wind cups or vane obstructed/dirty. Improper mounting location. Mechanical damage.	Clean wind cups and vane. Relocate the transmitter to an area free from obstructions and turbulence. Inspect for physical damage. If damaged, contact support.
Solar charging not working effectively.	Solar panel is dirty or obstructed. Incorrect orientation.	Clean the solar panel. Ensure the solar panel is facing directly south and is not shaded.
