What is the role of the TX44DTH-IT sensor for the La Crosse Technology WT280 weather station?
Frequently Asked Questions - 30/01/2026
Response Notice-Facile

The TX44DTH-IT is a wireless external sensor designed to extend the measurement capabilities of your La Crosse Technology WT280 station. It transmits real-time temperature and humidity from the outside to the station, allowing you to have a complete view of the weather conditions both inside and outside your home.

This sensor performs two essential complementary measurements:

  • Outdoor temperature transmitted directly to the WT280 display, allowing you to visualize the thermal variations of your outdoor environment.
  • Hygrometry (humidity level) of the outside air, with a detection range of 1 to 99%, useful for assessing climate comfort and planning your activities.

With a range of 100 meters in open space, the TX44DTH-IT communicates with the station via radio signal at a frequency of 868 MHz, without requiring any wiring. This greatly facilitates its installation away from your home, particularly on a facade, balcony, or garden post.

To optimize the sensor's operation, install it sheltered from direct weather by placing it under an eave, awning, or specialized garden shelter, while positioning it in an open area to ensure good radio signal reception. Avoid completely enclosed areas or those buried under too many materials that could block the 868 MHz transmission.

Once paired with your WT280, the TX44DTH-IT provides accurate weather data that enriches your experience of using the station. This outdoor information is particularly useful for making daily decisions: adjusting your clothing, watering your garden at the right time, or adjusting your home's heating based on actual outdoor conditions.
