# Connection type: serial or ethernet
# serial (the classic VantagePro)
# ethernet (the WeatherLinkIP or Serial-Ethernet bridge)
type = ethernet
# If the connection type is serial, a port must be specified:
# Debian, Ubuntu, Redhat, Fedora, and SuSE:
# /dev/ttyUSB0 is a common USB port name
# /dev/ttyS0 is a common serial port name
# BSD:
# /dev/cuaU0 is a common serial port name
port = /dev/ttyUSB0
# If the connection type is ethernet, an IP Address/hostname is required:
host = 10.10.10.10
