La Crosse Technology Wireless Wi‑Fi Weather & Wind Station V21‑WTH — Multi‑sensor Outdoor Kit with Large Indoor Display

The La Crosse Technology V21-WTH is a wireless Wi‑Fi weather and wind station that collects backyard wind, rain, temperature and humidity data and streams it to the included display and the La Crosse View app.

This professional-grade system combines multiple outdoor sensors with a large indoor display and built‑in Wi‑Fi so you can view detailed local conditions at home or on your phone. Each sensor transmits weather measurements up to 400 feet to the display, while the onboard Wi‑Fi module forwards readings to La Crosse servers and integrates AccuWeather forecasts and internet time when connected. The kit emphasizes durable sensor design, long battery life, and simple app connectivity for continuous remote monitoring.

How does the station deliver accurate backyard weather data?

The system uses separate, purpose-built sensors for wind speed, rainfall, and temperature/humidity so each measurement is optimized for its function. Sensors transmit on a robust 915 MHz channel to maintain signal strength, and the display records histories so you can review recent trends. When Wi‑Fi is active, the station also receives NWS and AccuWeather details to complement local readings.

• Dedicated wind cup sensor with replaceable cups and debris-shedding shape
• Self-emptying tipping rain bucket with level indicator for correct setup
• Temperature/humidity sensor designed for hanging or freestanding mounting
• 915 MHz transmission range up to approximately 400 feet in open air

What features does the display and app provide for monitoring?

The included display is the command center with a large LCD that shows colorful numbers and graphics, adjustable brightness, and a foldout kickstand for angled viewing. Intuitive top-mounted buttons let you cycle through sensors, set alerts, and view stored readings. Pairing with the La Crosse View app unlocks remote access, data backup, and sharing with friends while requiring a 2.4 GHz Wi‑Fi connection during setup.

• Large, easy-to-read LCD with brightness control and adjustable stand
• On-screen history for wind, temperature, and humidity with alert options
• Wi‑Fi upload to La Crosse servers and La Crosse View app for remote access
• Automatic internet time and AccuWeather integration when online

How durable and low‑maintenance are the outdoor sensors?

Sensors are engineered to resist common outdoor wear while keeping battery consumption low for extended life. The wind sensor’s shape sheds snow and debris, and its wind cups are easily replaceable. The rain gauge self‑empties to avoid overflow issues, and the temperature/humidity unit places batteries in a front compartment for simple access.

• Wind sensor designed to repel snow and debris and accept replacement cups
• Large-opening, self‑emptying rain bucket with visible level indicator
• Temperature/humidity sensor with front-facing battery compartment for easy changes
• Weatherproof housing and rugged components to withstand outdoor conditions

Who is this for? Homeowners, hobby meteorologists, small property managers, and anyone wanting detailed local weather data will benefit from the V21-WTH. It’s built for users who want both an attractive, easy-to-read indoor display and reliable remote access through an app, without the complexity of wired installations or additional gateways. If you need continuous local monitoring, historical wind and rain records, and Wi‑Fi connectivity to share data or receive forecasts, this La Crosse Technology station is a practical, durable solution.
