StormSiren can support an unlimited number of device specifications. The general form of a device specification is:

[integer]
device = device_type
to = device_target
alert = alert_types
areas = list of areas

Currently, StormSiren supports the following device types:

• email
• sms
• jabber
• media
• mythtv
• external programs
• OSD (On Screen Display)

Each device is capable of receiving specific alert types. These alert types include:

• statement
• forecast
• advisory
• watch
• warning

Along with being able to filter on specific alert types, StormSiren is capable of filtering each device to specific geographic areas. Geographic areas are specified using a colon separated list of location,State. The location can be either a city or the name of a county. The state should be the two letter abbreviate for the state. An example would be Warren,TN (County,State) and McMinnville,TN (City,State):

areas = Warren,TN:McMinnville,TN

A full example of an email device would be the following:

[1]
device = email
to = cfreeze@example.com
alert = watch,warning
areas = Rockwall,TX:Collin,TX:Dallas,TX:Kaufman,TX:Hunt,TX
