If Weather Underground detects rain in the area, use beam to close your garage door to protect everything in the garage.
This Trigger monitors changes in the current weather condition. When one of those conditions is met the Trigger fires. Currently only these simple conditions are supported: Rain, Snow, Cloudy, Clear.
This action will ask the controller to close the garage door you specify. If the garage door is already closed, then the door will remain closed.
