WeatherLink for Alarm Output Electronic Device Controller.
Use your Vantage Pro2 to set up customized alarm "recipes" that, in turn, control four switches. For example, you could set alarm that will switch only when the high wind speed is over 20 mph, the wind direction is between the south and west, and its 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/electronic control configuration tool, and datalogger. Compatible with Vantage Pro2. Not for use with WeatherLink for Mac... sorry. FREE Shipping USA & Int'l via USPS or UPS - usually 3-7 days in USA; 4-10 days Int'l
