WeatherLink® for Alarm Output Use your Vantage station to set up customized alarm “recipes” that, in turn, control four switches. For example, you can set an alarm that will switch only when the high wind speed is over 20 mph, the wind direction is between the south and west, and it’s between the hours of 6 a.m. and 9 p.m. “Recipes” can be as simple or as complicated as you need them to be. Includes WeatherLink software, alarm configuration tool, and datalogger. Requires Windows XP and above with an available serial port.
