Do I have to connect my WeatherLink Console to Wi-Fi for it to receive data from my Vantage Pro2 or Vantage Vue sensor suite?
No, the WeatherLink Console can receive data from your local sensors without a Wi-Fi connection. However, Wi-Fi is needed for keeping accurate time on the console and for firmware updates (which occur at 3:00 am local time if available). You do NOT need to be logged in to WeatherLink.com; you just need to be connected to Wi-Fi.
