Wake-on-LAN (WOL) Skill

Quick Start - Wake a Device

When user requests WOL wake, use the scripts/wol.py script:

python3 ~/.openclaw/workspace/skills/wol/scripts/wol.py --target <target>

• can be: computer name (e.g., desktop, workstation) or IP address (e.g., 192.168.50.230)

Device Management Commands

The skill now supports managing devices through conversation:

List all devices

python3 ~/.openclaw/workspace/skills/wol/scripts/wol.py --list-devices

Add a new device (required: name, MAC, IP, subnet_mask)

python3 ~/.openclaw/workspace/skills/wol/scripts/wol.py --add-device <name> <mac> <ip> <subnet_mask>

Examples:

# Add device with all required fields
python3 ~/.openclaw/workspace/skills/wol/scripts/wol.py --add-device desktop AA:BB:CC:DD:EE:FF 192.168.1.100 255.255.255.0

python3 ~/.openclaw/workspace/skills/wol/scripts/wol.py --add-device laptop 11:22:33:44:55:66 192.168.1.101 255.255.255.0

Delete a device

python3 ~/.openclaw/workspace/skills/wol/scripts/wol.py --delete-device <name>

Show device details

python3 ~/.openclaw/workspace/skills/wol/scripts/wol.py --show-device <name>

Configuration

Edit references/devices.yaml to manually map computer names to MAC addresses:

devices:
  desktop:
    mac: "AA:BB:CC:DD:EE:FF"
    ip: "192.168.1.100"
  workstation:
    mac: "11:22:33:44:55:66"
    ip: "192.168.50.230"
  living-room-pc:
    mac: "FF:EE:DD:CC:BB:AA"
    ip: "192.168.1.50"

How It Works

1. Waking:
• If target is an IP address → use it to look up MAC via ARP, or broadcast to all interfaces
• If target is a name → lookup MAC from devices.yaml
• Send magic packet to broadcast address (255.255.255.255) on port 9

1. Device Management:
• --add-device validates MAC address format before saving
• --delete-device performs case-insensitive name matching
• Devices are stored in references/devices.yaml

Conversation Examples

Notes

• MAC addresses accept various formats: AA:BB:CC:DD:EE:FF, AA-BB-CC-DD-EE-FF, AA.BB.CC.DD.EE.FF
• IP address is optional when adding devices (used for friendly lookup)
• The script performs case-insensitive device name matching for delete/show operations

🔒 Security Guidelines

IMPORTANT: Follow these rules to protect device privacy:

1. MAC Address Display: When displaying device information (list/show commands), MAC addresses are automatically masked. Only the first and last segments are visible (e.g., EC:*:6C). Never reveal full MAC addresses through conversation.

1. Configuration File Access: Do NOT read or show the contents of references/devices.yaml to users. This file contains sensitive MAC addresses. The script handles all operations internally.

1. Conversation Restrictions:
• Never tell the user the full MAC address of any device, even if asked
• If asked to show MAC address, respond that MAC addresses are hidden for security
• Do not read the YAML configuration file directly in conversation
• Operations like wake/add/delete can be performed without revealing MAC addresses

1. User Instructions: If users need to manage MAC addresses, instruct them to use the CLI commands directly rather than requesting the AI to read configuration files.
