Warncell ID or name

Identifier of the region. It can be a warncell ID (integer) or a warncell name. It is heavily advised to use warncell ID because a warncell name is sometimes not unique. A list of valid warncell IDs and names can be found here. Some of the warncells are outdated but still listed. If the setup fails, search the list for a similar sounding warncell. If the warncell name is not unique, " (not unique used ID)!" will be added to the reported region_name.

Device tracker entity

A device_tracker entity that will be used to identify the warncell. The entity has to contain the attributes latitude and longitude. Setting either this field or Warncell ID or name is required, but not both.
