Davis Instruments Vantage Pro/Pro2/Vue

Features

The driver supports all Davis Instruments line of Vantage weather stations that are connected using the USB Data Logger connecter. The driver displays data for the following parameters in metric units:

• Weather: Weather forecast (clear, cloudy, rainy...etc). 0 for Clear/Sunny, 1 for partly cloudy or light haze, 2 for everything else.
• Temperature (C): Inside temperature in Celcuis.
• Humidity (C): Relative Humidity %
• Barometer (millibars): Barometer pressure value.
• Wind Speed: Wind speed in kilometers per hour.
• Wind Direction: 0 is for no data. 90 East, 180 South, 270 South, 360 North.
• Rain Rate: Rain rate in mm/hour.
• Solar Radiation: Solar Radiation in watt/meter^2

All parameter values have an Ok, Warning, and Alert ranges that can be specified by the user in the Parameters tab. Weather, temperature, wind speed, and rain rate are considered Critical Paramters. Critical paramters are listed in the main control tab in the Weather status property. The user can specify the minimum and maximum range for each zone. Any value outside the Warning zone is automatically considered Alert. The overall weather status property reflects the worse state of the individual critical parameters. If one critical paramter status is Warning while another is Alert then the overall weather status property is Alert.

Operation

Before you connect, check that the port and baud rate settings in the Options tab are correct. By default, the port is /dev/vantage which is selected automatically by the udev rules file once you connect the station to the PC. You can specify the update period is seconds (default 60) in the main control panel. To update weather data manually, press the Refresh button. If you change the paramter ranges under the Paramters tab, save the ranges in the configuratio file by clicking on Save in the Options tab.
