description	Control Philips Wiz smart lights via Node.js library. Use when Claude needs to: (1) Create WizLight instances with IP addresses, (2) Control light status (on/off), (3) Set colors (RGB, RGBW, RGBCW), (4) Adjust brightness, (5) Retrieve light status, (6) Configure connection options (port, timeout, retries), (7) Schedule light control with node-cron, (8) Run ready-made light control scripts

Wiz-Light Skill

TypeScript library for controlling Philips Wiz smart lights via UDP communication.

Quick Start

CRITICAL: Before controlling any light, ALWAYS ask the user for the IP address:

"What is the IP address of your Wiz light?" or "Where is your Wiz light located?" or "What IP does your Wiz light use?"

For Ready-Made Scripts

IMPORTANT: Scripts MUST be run from the skill's directory. Do NOT run them from outside the skill folder.

# Navigate to the skill directory first
cd wiz-light

# Install dependencies
npm install

# Turn light ON
node scripts/light-on.js 192.168.1.2

# Turn light OFF
node scripts/light-off.js 192.168.1.2

# Set color with brightness
node scripts/light-color.js 192.168.1.2 38899 blue 80

# Check status
node scripts/light-status.js 192.168.1.2

For Custom Scripts

If creating custom light control scripts, I will automatically check for and set up your Node.js project if needed:

1. Ask for your Wiz light IP address
2. Check if you have a Node.js project (check for package.json)
3. If NO project exists, automatically:
   • Initialize a new Node.js project in your current directory with npm init -y
   • Set "type": "module" in package.json
   • Install wiz-light library
   • (Optional) Install node-cron if you need scheduling
4. Create your custom script in your current directory
5. Provide instructions to run it from your current directory

Using the Library

import { WizLight } from 'wiz-light';

// Create instance with IP and port (IP must be provided)
const wl = new WizLight('192.168.1.2', { port: 38899 });

// Turn light ON
await wl.setLightStatus(true);

// Turn light OFF
await wl.setLightStatus(false);

// Set properties
await wl.setLightProps({
  r: 0,
  g: 255,
  b: 0,
  c: 0,
  w: 100,
  dimming: 100
});

// Get current status
const status = await wl.getStatus();
console.log(status.result);

Color Settings

IMPORTANT: When calling setLightProps(), both w (warm) and c (cool) MUST be provided with one set to 100 and the other set to 0:

• Warm colors: Use w: 100 and c: 0
• Cool colors: Use c: 100 and w: 0

This ensures only one channel is active for clear color representation.

Configuration Options

const wl = new WizLight('192.168.1.2', {
  // Port number (default: 38899)
  port: 38899,

  // Time to wait before retrying in ms (default: 1000)
  statusCheckTimeout: 1000,

  // Number of retry attempts (default: 5)
  retryTimes: 5
});

Scheduling Light Control

Use node-cron to schedule automatic light control. Use the library directly for scheduling - scripts are not suitable for scheduled tasks.

import { WizLight } from 'wiz-light';
import cron from 'node-cron';

const wl = new WizLight('192.168.1.2', { port: 38899 });

// Schedule light to turn ON every day at 6:00 AM
cron.schedule('0 6 * * *', async () => {
  await wl.setLightStatus(true);
});

// Schedule light to turn OFF every day at 10:00 PM
cron.schedule('0 22 * * *', async () => {
  await wl.setLightStatus(false);
});

See references/scheduling.md for complete scheduling examples including:

• Daily routines
• Weekday vs weekend schedules
• Work hours automation
• Color cycling
• Multiple light control
• Error handling and cleanup

API Reference

See references/API.md for complete API documentation including all types and methods.

Usage Examples

See references/examples.md for common use cases and patterns.

Ready-Made Scripts

The skill includes ready-made scripts for quick light control. When the user wants to perform a direct action, first ask for the IP address, then use these scripts.

Available Scripts

• scripts/light-on.js - Turn light ON with specified color (default: white)
• scripts/light-off.js - Turn light OFF
• scripts/light-color.js - Set light to specific color
• scripts/light-status.js - Check current light status

Running Scripts

IMPORTANT: Scripts MUST be run from the skill's directory. Do NOT run them from outside the skill folder.

# Navigate to the skill directory first
cd wiz-light

# Install dependencies
npm install

# Turn on light with default white color
node scripts/light-on.js 192.168.1.2

# Turn on light with custom color and brightness
node scripts/light-on.js 192.168.1.2 38899 red 100

# Turn off light
node scripts/light-off.js 192.168.1.2

# Set specific color
node scripts/light-color.js 192.168.1.2 38899 blue 80

# Check status
node scripts/light-status.js 192.168.1.2

CRITICAL:

• IP address is REQUIRED for all scripts
• Port is optional (default: 38899)
• Scripts MUST be run from the skill's directory (where package.json and scripts folder are located)

When to Use Scripts vs. Writing Code

Use READY-MADE scripts for:

• Simple, one-time light control actions
• Quick color changes
• Turning lights on/off
• User wants immediate results without coding
• Testing light control quickly

Use the LIBRARY for:

• Complex automation and scheduling
• Integrating with other systems
• Repeated automated tasks
• Building custom applications
• Creating custom scripts with specific requirements

Auto-Setup for New Projects

If creating custom light control scripts and don't have a Node.js project, I will automatically:

1. Check if you have a Node.js project (check for package.json)
2. If NO project exists:
   • Initialize a new Node.js project in your current directory with npm init -y
   • Set "type": "module" in package.json (for ES module imports)
   • Install wiz-light library
   • (Optional) Install node-cron if you need scheduling
3. Create your custom script in your current directory
4. Once set up, proceed with your script creation
