+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+This is a Home Assistant Blueprints repository containing reusable automation templates for smart home systems. All blueprints are YAML configuration files that can be imported directly into Home Assistant.
+
+## Common Development Tasks
+
+### Testing & Validation
+- **Blueprint Validation**: Use Home Assistant's built-in blueprint importer to validate YAML syntax
+- **Template Testing**: Test Jinja2 templates in Home Assistant Developer Tools → Template tab
+- **Live Testing**: Import blueprint into Home Assistant and create test automation to verify behavior
+
+### Working with Blueprints
+When modifying or creating blueprints:
+1. Follow the standard Home Assistant blueprint schema structure
+2. Always include comprehensive descriptions for user clarity
+3. Provide sensible defaults for all input parameters
+4. Use proper selectors for entity inputs (entity, device, area selectors)
+5. Test templates for edge cases (unavailable entities, null states)
+
+## Architecture & Code Structure
+
+### Blueprint Components
+Every blueprint follows this structure:
+- **blueprint:** Metadata section with name, description, domain (always "automation")
+- **input:** User-configurable parameters with selectors and defaults
+- **trigger:** Event triggers (state changes, time patterns, device events)
+- **condition:** Optional conditional logic
+- **variables:** Template variables for complex logic
+- **action:** Automation actions to execute
+- **mode:** Execution mode (single, restart, queued, parallel)
+
+### Key Patterns
+
+#### Template Safety
+Always use fallback defaults in templates:
+```yaml
+{{ states('sensor.temperature') | float(0) }}
+{{ state_attr('device.battery', 'battery_level') | int(100) }}
+```
+
+#### Entity Expansion
+Use expand() for working with entity groups:
+```yaml
+{% for entity_id in expand(battery_sensors) | map(attribute='entity_id') | list %}
+```
+
+#### Z-Wave Event Handling
+Z-Wave central scene events follow this pattern:
+```yaml
+trigger:
+  - platform: event
+    event_type: zwave_js_value_notification
+    event_data:
+      command_class: 91  # Central Scene
+      property_key: "001"  # Scene ID
+```
+
+#### Complex State Calculations
+Use namespace objects for accumulating values:
+```yaml
+{% set ns = namespace(total=0, count=0) %}
+{% for entity in entities %}
+  {% set ns.total = ns.total + states(entity) | float(0) %}
+  {% set ns.count = ns.count + 1 %}
+{% endfor %}
+```
+
+## Blueprint Categories
+
+### HVAC & Climate Control
+- **hvac-failure-monitor.yaml**: Monitors HVAC performance using temperature differentials
+- **fan-management.yaml**: Bathroom fan automation with light triggers
+- **fan-cadence.yaml**: Periodic fan cycling with override protection
+
+### Power & Energy
+- **power-monitoring.yaml**: Detects power spikes for appliance identification
+- **battery-monitor.yaml**: Multi-device battery level monitoring
+
+### Smart Switches & Scenes
+- **multi-tap-automation.yaml**: Z-Wave switch multi-tap scene control
+- **multi-tap-automation-homeseer-and-zooz.yaml**: Enhanced multi-tap with HomeSeer/Zooz support
+- **indication.yaml**: HomeSeer WD200+ LED indicator control
+
+### Security & Utility
+- **simulated-presence.yaml**: Random light automation for security
+- **state-opposite.yaml**: Bidirectional entity state synchronization
+
+## Important Implementation Notes
+
+### Input Validation
+- Use proper selector types (number with min/max, boolean, entity with domain filter)
+- Always provide defaults to prevent undefined errors
+- Use multi-select for flexibility where appropriate
+
+### Error Handling
+- Check entity availability before actions
+- Use conditional sequences for optional actions
+- Implement proper fallbacks for missing data
+
+### Performance Considerations
+- Use appropriate automation modes (single for exclusive, restart for updates)
+- Minimize template complexity in frequently-triggered automations
+- Consider using time patterns instead of constant state monitoring
+
+### Common Issues & Solutions
+- **Template errors**: Test in Developer Tools first
+- **Entity unavailable**: Add availability checks in conditions
+- **Z-Wave events not firing**: Verify device supports Central Scene command class
+- **HVAC monitoring false positives**: Adjust temperature thresholds and time windows

+blueprint:

+  description: >
+    Turns lights on when motion is detected and keeps them on for a specified duration

+    Features:
+    - Multiple light support
+    - Configurable timeout after motion stops
