@weather-display can confirm this, but my experience and understanding is that if you do not check the “use UDP data” box in the WD cronweatherflow component then WD will collect the data (and log it) from the WF backend from anywhere that has an Internet connection.
@vreihen is quite correct that if you want to log the UDP data stream directly then your logging computer must have an interface in the same network segment as the Hub since UDP broadcasts do not travel outside their local subnet.
