2.1.0 CAP format alerts

[2.1.0] - 2026-01-13

Breaking Changes

• Sensor state changed: State now represents the count of active alerts
  • Previous: State was highest activity level (1-5) or text string "1" for no alerts
  • Current: State is integer count (0 = no alerts, 1 = one alert, 2 = two alerts, etc.)
  • Severity information still available in highest_level and highest_level_numeric attributes
  • Impact: Automations or templates using states('sensor.norway_alerts_*') for severity level need updating

Added

• CAP format conversion - Optional conversion of NVE warnings to CAP (Common Alerting Protocol) format
  • Enabled by default for new sensors
  • Existing sensors preserve their original format for backward compatibility
  • Allows unified display of NVE and Met.no alerts using the same template
  • Only available for NVE warnings (landslide, flood, avalanche) - Met.no alerts are always CAP
• Template blueprint - Pre-built template sensor blueprint for displaying CAP-formatted alerts
  • Available in blueprints/template/cap_alert_markdown_sensor.yaml
  • Import from GitHub for easy setup
  • Configurable display options (icons, status, maps)
  • Creates formatted markdown sensor for use in markdown cards

Changed

• CAP format option hidden for Met.no weather alerts (always CAP format)
