# =============================================================================
# Template Sensors for Timer Remaining Time
# =============================================================================
# Add to configuration.yaml: template: !include templates.yaml
# Or merge into your existing template configuration.
#
# Each area gets a sensor that calculates:
#   - Remaining seconds (state)
#   - Original duration in seconds (attribute)
#   - Timer state: idle, active, paused (attribute)
#   - Progress percentage (attribute)
#
# Naming convention: sensor.<area_id>_timer_remaining_seconds
#
# To add a new area, copy the template block and replace the area name.
# =============================================================================

# Triggered sensors update every second when timers are active
- trigger:
    # Update every second for active timers
    - platform: time_pattern
      seconds: "/1"
    # Also update when any timer state changes
    - platform: state
      entity_id:
        - timer.kitchen
        - timer.bedroom
        - timer.playroom
        # Add more timer entities here as needed
