node-red-contrib-philips-airplus 0.1.0

Philips Air+ cloud integration for air purifiers and humidifiers

npm install node-red-contrib-philips-airplus

node-red-contrib-philips-airplus

Node-RED nodes for Philips Air+ purifiers and humidifiers via cloud API.

Features

• Real-time device status via WebSocket MQTT
• OAuth authentication (same as mobile app)
• Supports multiple devices per account
• Auto token refresh

Supported Devices

AC3737 and other v3 protocol devices only. This package uses the v3 AWS IoT protocol with field names like D03102 (power) and D0310C (mode).

Older devices using v1 or v2 protocols are not supported.

Installation

Via npm

cd ~/.node-red
npm install node-red-contrib-philips-airplus

Then restart Node-RED.

Via Palette Manager

1. Open Node-RED editor
2. Menu → Manage palette → Install tab
3. Search for "philips-airplus"
4. Click Install

Nodes

airplus-account (config node)

Manages authentication and connection to Philips cloud.

Setup:

1. Add config node and click "Get Auth URL"
2. Open URL in browser, log in to Philips account
3. Copy redirect URL (com.philips.air://loginredirect?code=...)
4. Paste in config node and click "Exchange Code"

airplus-status

Receives real-time status updates from a device.

Output:

msg.payload = {
    power: true,           // on/off
    mode: 'auto',          // auto, sleep, turbo, manual
    fanSpeed: 8,           // 1-18
    pm25: 12,              // ug/m3
    humidity: 45,          // %
    temperature: 22,       // celsius
    timestamp: 1704067200000
};
msg.deviceId = 'da-xxx';
msg.deviceName = 'Living Room';

airplus-control

Sends control commands to a device.

Partial updates supported: Send only the properties you want to change. Omitted properties remain unchanged.

Input (simple format):

// Change any combination of properties:
msg.payload = {
    power: true,           // on/off (optional)
    mode: 'auto',          // auto, sleep, turbo, manual (optional)
    fanSpeed: 1,           // 1-2 manual speed (optional, AC3737 has 2 speeds)
    targetHumidity: 50,    // 40-70, humidifiers only (optional)
    childLock: false,      // boolean (optional)
    displayLight: 50       // 0-100: 0=off, 50=dim, 100=bright (optional)
};

Partial update examples:

msg.payload = { power: true };              // Just turn on, keep mode
msg.payload = { mode: 'sleep' };            // Just change mode
msg.payload = { power: true, mode: 'auto' }; // Turn on in auto mode
msg.payload = { fanSpeed: 12 };             // Just adjust fan speed

Refresh command:

msg.topic = 'refresh';
msg.payload = {};  // ignored

Outputs:

• Port 1: Success with msg.controlResult
• Port 2: Error with msg.error

Usage with inject nodes:

[Inject: {power: true}]      → Power On
[Inject: {power: false}]     → Power Off
[Inject: {mode: 'auto'}]     → Auto Mode
[Inject: {mode: 'sleep'}]    → Sleep Mode
[Inject: {fanSpeed: 12}]     → Change Fan Speed
[Inject: topic='refresh']    → Fetch Status

CLI Authentication Tool

The package includes a CLI tool for authenticating outside of Node-RED:

npm run auth

Note: The headless Playwright approach is recommended as the manual method's reliability depends on browser behavior.

To install Playwright for headless auth:

npm install --no-save playwright

Examples

See examples/control-test.json for a complete test flow with inject nodes for all control commands.

Troubleshooting

OAuth authentication fails

• Check browser popup blockers
• Try CLI auth tool: npm run auth
• Ensure you're using correct Philips account credentials

MQTT connection issues

• Verify device is online in Philips app
• Check credentials haven't expired (re-authenticate if needed)
• Account node shows connection status for each device

Node shows "disconnected"

• Account config may need re-authentication
• Click "Clear Credentials" and authenticate again

Disclaimer

This package is based on reverse-engineered protocol from the official Philips Air+ Android app. It is not affiliated with or endorsed by Philips.

Compatibility:

• Supports v3 protocol devices (AC3737/Carnation, Apollo series)
• V1/V2 devices are not compatible

Stability: Protocol may change if Philips updates their cloud API. This is version 0.x indicating the API surface may evolve.

Protocol

Based on reverse-engineered Philips Air+ cloud API:

• OAuth via cdc.accounts.home.id
• REST API at prod.eu-da.iot.versuni.com
• MQTT over WebSocket at ats.prod.eu-da.iot.versuni.com

Development

# Install dependencies
npm install

# Run tests
npm test
