wyrestorm-networkhd 0.1.0

Python client library for WyreStorm NetworkHD API operations - matrix switching, device control, video walls, and multiview.

WyreStorm NetworkHD API Client

A Python client library for interacting with WyreStorm NetworkHD API operations. Supports all major command categories including matrix switching, device control, video walls, multiview, and more.

Installation

pip install wyrestorm-networkhd

Quick Start

from wyrestorm_networkhd import NetworkHDClient, ConnectionType, NHDAPI

# Create client with SSH connection
client = NetworkHDClient(
    connection_type=ConnectionType.SSH,
    host="192.168.1.100",
    port=10022,
    username="wyrestorm",
    password="networkhd"
)

# Use with context manager
async with client:
    # Create API wrapper
    api = NHDAPI(client)

    # Execute commands and get typed responses
    device_list = await api.api_query.get_devicelist()
    matrix_info = await api.api_query.matrix_get()
    await api.video_wall.scene_active("office", "splitmode")

Features

• Strongly Typed: Full type hints and data models for all API responses
• Async/Await Support: Built for modern Python async applications
• Multiple Connection Types: SSH connections supported, but extensible for other connection types in the future (RS232, Telnet) if required.
• Comprehensive API Coverage: All NetworkHD API commands supported
• Error Handling: Robust error handling with custom exception types
• Context Manager Support: Clean resource management

API Categories

API categories match those in the API Reference (see below).

• System Configuration: Version info, IP settings, device lists
• Device Configuration: Device names, info, and status
• Matrix Switching: Video, audio, USB, infrared, and serial routing
• Video Walls: Scene management and logical screen control
• Multiview: Preset and custom layout management
• Device Control: Reboot, reset, and port switching
• Notifications: Real-time device status updates

Logging

The package includes comprehensive logging for debugging and monitoring. Logging is configured automatically but can be customized.

Default Logging

By default, logs are output to the console at INFO level. The following events are logged:

• INFO: Connection establishment/disconnection, command execution
• DEBUG: Detailed command/response data, SSH connection details
• ERROR: Connection failures, command errors

Customizing Logging

from wyrestorm_networkhd.logging_config import setup_logging

# Set debug level for verbose output
setup_logging(level="DEBUG")

# Log to file
setup_logging(level="INFO", log_file="logs/wyrestorm_networkhd.log")

# Custom format
setup_logging(
    level="DEBUG",
    log_format="%(levelname)s - %(name)s - %(message)s"
)

Log Levels

• DEBUG: All details including commands, responses, and SSH operations
• INFO: Connection events and command execution (default)
• WARNING: Non-critical issues
• ERROR: Errors and failures
• CRITICAL: Critical system failures

Environment Variables

Set LOG_LEVEL environment variable to control logging level:

export LOG_LEVEL=DEBUG
python your_script.py

Security Configuration

The client supports configurable SSH host key verification policies to balance security with usability in different deployment scenarios.

Host Key Verification Policies

• HostKeyPolicy.WARN (default): Warns about unknown hosts but continues

  • Good balance between security and usability
  • Provides visibility into security issues
  • Suitable for production with monitoring

• HostKeyPolicy.REJECT: Rejects connections to unknown hosts

  • Most secure option for production environments
  • Requires known host keys to be pre-configured
  • Best for environments with stable, known devices

• HostKeyPolicy.AUTO_ADD: Automatically trusts unknown host keys

  • Good for development and testing environments
  • ⚠️ Security Warning: Vulnerable to man-in-the-middle attacks
  • Use only in controlled, trusted environments

• HostKeyPolicy.ASK: Prompts user for confirmation

  • Interactive mode for development/testing
  • Requires user interaction in terminal
  • Good for controlled testing environments

Usage Examples

from wyrestorm_networkhd import NetworkHDClient, HostKeyPolicy, ConnectionType

# Default behavior (WARN policy)
client = NetworkHDClient(
    connection_type=ConnectionType.SSH,
    host="192.168.1.100",
    password="secret"
)

# Secure production setup
client = NetworkHDClient(
    connection_type=ConnectionType.SSH,
    host="192.168.1.100",
    password="secret",
    ssh_host_key_policy=HostKeyPolicy.REJECT
)

# Auto-add mode for development/testing
client = NetworkHDClient(
    connection_type=ConnectionType.SSH,
    host="192.168.1.100",
    password="secret",
    ssh_host_key_policy=HostKeyPolicy.AUTO_ADD
)

Security Recommendations

• Production Environments: Use REJECT or WARN policies (WARN is default)
• Development/Testing: Use AUTO_ADD or ASK policies
• Controlled Networks: AUTO_ADD may be acceptable if network security is assured
• Monitor Logs: Always monitor logs for security warnings when using permissive policies
• Default Behavior: New clients now use WARN policy by default for better security

🧪 Testing

This project uses pytest for comprehensive testing with coverage reporting.

Running Tests
