WeatherLink.com emulates the behavior of your console (or Envoy). It stores four times the amount of data on your console/Envoy. Depending on the archive interval, up to 800 days (just over 2 years) worth of weather data will be stored on WeatherLink.com. If you wish to keep your weather data for a longer duration, we suggest you periodically download your weather data from WeatherLink.com to your own PC using the WeatherLink software.
