In http://www.hometheaterforum.com/uub/Forum2/HTML/005744.html[*]Exterior sprinklers are controlled by the system and announcements are made when they're activated. Eventually I'm going to put a small weather station on the roof so I can monitor wind speed, rainfall, etc. That way, if it's too windy to water or it has recently rained, the system can automatically postpone watering until a later time. There are others who have scripts (I haven't done this yet, but really want to!) that download the forecast off the net every morning before deciding whether to water. If it calls for rain, the sprinklers don't water that day. A weather station can then measure rainfall in conjunction with this, so if it rained for x amount of time, but not enough to really soak the lawn, the sprinklers could go ahead and run for a shorter amount of time.[*]Most of my houseplants are watered automatically by the system.
