+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+This is a Python automation tool that integrates UniFi Access with Airbnb/Hostex reservations, automatically creating and managing visitor access for Airbnb guests. The system fetches reservations from either Hostex API or Airbnb ICS feed, creates UniFi Access visitor accounts with PIN codes based on phone numbers, and provides cross-verification between multiple booking systems.
+
+## Core Commands
+
+### Development and Execution
+- **Run the application**: `python3 main.py`
+- **Install dependencies**: `pip install -r requirements.txt`
+- **Run with verbose logging**: `python3 main.py -v`
+- **Specify custom log file**: `python3 main.py -l custom.log`
+- **List available door groups**: `python3 main.py --list-door-groups`
+
+### Configuration Setup
+- **Setup configuration**: `cp unifi.conf.example unifi.conf` then edit with actual credentials
+- **Configuration file**: `unifi.conf` (contains API tokens, URLs, and settings)
+
+## Architecture Overview
+
+### Core Components
+
+1. **main.py** - Entry point and orchestration
+   - Handles command-line arguments and logging setup
+   - Coordinates all managers and performs cross-system verification
+   - Implements `verify_across_systems()` for data consistency checks
+
+2. **unifi_access.py** - UniFi Access API integration
+   - `UnifiAccessManager` class handles all UniFi Access operations
+   - Creates/deletes visitors, assigns PIN codes, manages door group access
+   - Processes reservations and maintains visitor lifecycle
+
+3. **hostex_api.py** - Hostex API integration
+   - `HostexManager` fetches reservations from Hostex booking platform
+   - Simple API wrapper for reservation data
+
+4. **ics_parser.py** - Airbnb ICS calendar parsing
+   - `ICSParser` processes Airbnb calendar feeds
+   - Extracts reservation data and PIN codes from ICS events
+
+5. **notification.py** - Simplepush notifications
+   - `NotificationManager` sends status updates and alerts
+   - Configurable notification system for operational updates
+
+6. **config.py** - Configuration management
+   - Centralizes configuration loading from `unifi.conf`
+   - Handles API credentials, timing settings, and feature flags
+
+7. **utils.py** - Shared utilities
+   - Logging setup and configuration
+
+### Data Flow Architecture
+
+```
+Hostex API ──┐
+             ├──► Cross-Verification ──► UniFi Access API
+ICS Feed ────┘                          (Visitor Management)
+                                              │
+                                              ▼
+                                        Simplepush Notifications
+```
+
+### Key Integration Points
+
+- **Reservation Sources**: Supports both Hostex API and Airbnb ICS feeds
+- **PIN Code Generation**: Uses last N digits of guest phone numbers
+- **Cross-Verification**: Matches reservations across systems to detect discrepancies
+- **Visitor Lifecycle**: Automatically creates visitors for upcoming stays, deletes past/completed visits
+- **Door Access**: Assigns visitors to configurable door groups in UniFi Access
+
+## Configuration Structure
+
+The `unifi.conf` file contains these key sections:
+- `[UniFi]`: Access controller API endpoint and authentication token
+- `[Hostex]`: Hostex API credentials (optional if using ICS only)
+- `[Airbnb]`: ICS calendar feed URL (optional if using Hostex only)
+- `[Door]`: Default door group ID for visitor access
+- `[Visitor]`: Check-in/out times and PIN code settings
+- `[Simplepush]`: Notification service configuration
+- `[General]`: Logging and PIN code digit count
+
+## Development Notes
+
+### Dependencies
+- `requests`: HTTP API calls to UniFi Access and Hostex
+- `icalendar`: Parsing Airbnb ICS calendar feeds
+- `urllib3`: HTTP utilities (with SSL warning suppression)
+- `configparser`: Configuration file parsing
+
+### Logging Strategy
+- Comprehensive debug logging available with `-v` flag
+- File-based logging for operational history
+- Different log levels for console vs file output
+
+### API Integrations
+- **UniFi Access**: RESTful API for visitor management, requires authentication token
+- **Hostex**: Booking platform API for reservation data
+- **Simplepush**: Simple HTTP-based notification service
+- **Airbnb ICS**: Calendar feed parsing for reservation extraction
+
+### Testing and Verification
+- Use `--list-door-groups` to verify UniFi Access connectivity and available door groups
+- Run with `-v` flag to see detailed operation logs
+- Check log files for historical operation data and error analysis

+# Docker Setup for UniFi Access Airbnb Integration
+
+## Quick Start
+
+1. **Build and run continuously** (checks every 6 hours):
+```bash
+docker-compose up -d
+```
+
+2. **Run once manually**:
+```bash
+docker-compose --profile manual up unifi-access-airbnb-once
+```
+
+3. **View logs**:
+```bash
+docker-compose logs -f
+# Or check the logs directory: ./logs/unifi_access_airbnb.log
+```
+
+## Configuration
+
+- **Config file**: Edit `unifi.conf` on the host - it's mounted read-only into the container
+- **Logs**: Persistent in `./logs/` directory
+- **Timezone**: Set in docker-compose.yml (default: America/New_York)
+
+## Automation Options
+
+### Option 1: Continuous Container (Recommended)
+```bash
+docker-compose up -d
+```
+Runs every 6 hours automatically. Change interval by modifying `sleep 21600` in docker-compose.yml.
+
+### Option 2: Cron Job + Manual Container
+```bash
+# Add to crontab to run daily at 8 AM:
+0 8 * * * cd /path/to/project && docker-compose --profile manual up unifi-access-airbnb-once
+```
+
+### Option 3: Windows Task Scheduler
+Create a scheduled task that runs:
+```cmd
+docker-compose --profile manual up unifi-access-airbnb-once
+```
+
+## Commands
+
+- **Stop**: `docker-compose down`
+- **Rebuild**: `docker-compose build`
+- **View container status**: `docker-compose ps`
+- **Interactive shell**: `docker-compose exec unifi-access-airbnb sh`
+
+## Raspberry Pi Deployment
+
+### Compatibility
+✅ **Raspberry Pi 4/5** (ARM64) - Full support  
+✅ **Raspberry Pi 3B+** (ARM32/ARMv7) - Full support  
+✅ **Raspberry Pi Zero 2 W** (ARM64) - Works but slower  
+
+### Pi-Specific Setup
+```bash
+# 1. Install Docker (if not already installed)
+curl -fsSL https://get.docker.com -o get-docker.sh
+sudo sh get-docker.sh
+sudo usermod -aG docker pi
+
+# 2. Install docker-compose
+sudo apt update
+sudo apt install docker-compose-plugin
+
+# 3. Clone and run your project
+git clone <your-repo>
+cd unifi-access-airbnb
+docker-compose up -d
+```
+
+### Performance Notes
+- **Pi 4/5**: Excellent performance, recommended for production
+- **Pi 3B+**: Good performance, slightly slower container startup
+- **Pi Zero 2**: Functional but slower, consider running less frequently
+
+### Power Management
+For reliable operation on Pi:
+```yaml
+# Add to docker-compose.yml services section:
+restart: always
+deploy:
+  resources:
+    limits:
+      memory: 128M
+```
+
+## Troubleshooting
+
+- **Check logs**: `docker-compose logs unifi-access-airbnb`
+- **Test config**: `docker-compose --profile manual up unifi-access-airbnb-once`
+- **Network issues**: Ensure container can reach UniFi controller IP (10.0.1.20)
+- **Pi-specific**: Check `docker --version` and ensure Docker is running: `sudo systemctl status docker`

+- OR UniFi Cloud Key Gen2+ with Protect
+
+**Planned Features:**
+- **Guest Check-in Recording**: Automatically start recording when guests arrive
+- **Stay Duration Recording**: Record during entire guest stay period
+- **Checkout Verification**: Capture departure recordings
+- **Incident Documentation**: Archive recordings for property protection
+- **Guest Privacy**: Automatic recording pause/resume based on occupancy
+
+**Implementation Ideas:**
+- Integrate with UniFi Protect API for camera control
+- Coordinate recording schedules with visitor access periods
+- Provide guest notification of recording periods (legal compliance)
+- Archive system for easy retrieval of guest-specific recordings
+
+**Benefits:**
+- Property protection during guest stays
+- Incident documentation and liability protection
+- Automated recording management tied to booking system
+- Enhanced security without manual camera management
+
