The Wireless Professional Weather Station from La Crosse Technology offers all the weather information you need so not to ruin your day. The dynamic color forecast icons, with changing seasonal foliage, show what the weather is going to be like for the day. Along with your personal, up-to-the-minute wind speed & direction, and indoor/outdoor temperature and humidity, you know what is happening inside and outside your home, providing you with the information if to wear a jacket or if a good time to water the lawn. When using the connectable feature, you now add enhanced features, including weather data from AccuWeather with detailed forecast information such as, hourly & daily temps, precipitation chances, UV index & Air Quality, as well as additional icons to keep you up to date to future weather. Add-on sensors available (sold separately) enhance your system. NOTE: When using the free La Crosse View App, confirm your mobile device, for remote monitoring, is connected to a 2.4 GHz Wi-Fi network before you connect to your station. Some routers use 5 GHz frequency for media streaming and 2.4 GHz for everything else.
