• Dynamic Device Discovery: Automatically discovers and configures Winix purifiers linked to your account.
• Control: Power on/off, switch between sleep/auto/manual modes, and adjust airflow speed.
• Customization: Optionally expose Air Quality, Ambient Light, Plasmawave, Auto Mode, and Sleep Mode switches to HomeKit.
• Filter Management: Exposes the remaining filter life and provides an alert when it's time to change the filter, configurable to trigger at a specified percentage of remaining filter life.
• Efficiency: Features Winix API response caching to minimize requests and avoid rate limiting.
• Reliability: Automatically refreshes device list on a configurable interval to ensure devices are always up-to-date.
• Seamless Authentication: Automatically refreshes your Winix authentication token in the background, so you no longer need to manually re-authorize every 30 days.
• Encrypted Storage: Your Winix account password and refresh token are securely stored on disk using encryption, keeping your credentials safe.

This plugin officially supports the following Winix air purifiers:

• C545
• C610
• C909

While other models aren't explicitly blocked, they're not yet officially supported and may not work as expected.

Winix's system limits users to a single active session per account. When the same account is used simultaneously on the Winix app and Homebridge, it can lead to being logged out from one of the sessions. An alternate account dedicated to Homebridge prevents this issue, ensuring stable operation without frequent authentication disruptions.

Yes, this is an annoying and tedious one-time setup, but it is well worth not having to continually fix authentication issues.

To create and link an alternate Winix account, please follow the instructions in the Alternate Winix Account: Creating and Linking Wiki page.

For added security, you should set the WINIX_ENCRYPTION_KEY environment variable when running Homebridge. This will allow you to use your own custom encryption key string to protect your stored password and refresh token. If this variable is not set, the plugin will use a static default key, which is less secure. Directions for setting custom environment variables can be found in the Homebridge documentation.

Easily configure the plugin through the Homebridge Config UI X. Simply provide your Winix account credentials for automatic device discovery and provisioning.

While not recommended, if manual setup is required, add the following to the platforms section of your config.json:

{
  "platforms": [
    {
      "exposeAirQuality": true,
      "exposeAmbientLight": true,
      "exposePlasmawave": false,
      "exposeAutoSwitch": false,
      "exposeSleepSwitch": false,
      "filterReplacementIndicatorPercentage": 10,
      "cacheIntervalSeconds": 300,
      "deviceRefreshIntervalMinutes": 60,
      "auth": {
        "username": "your-email@domain.com",
        "password": "<encrypted-winix-password> (see below)",
        "userId": "f470ce5f-6b8e-44b4-a6db-b7f4d4c6f851"
      },
      "deviceOverrides": [
        {
          "deviceId": "123ABC456DEF_abc123xyz",
          "serialNumber": "WNXAI12345678",
          "nameDevice": "Living Room Air Purifier"
        },
        {
          "deviceId": "789XYZ987VWX_xyz789abc",
          "serialNumber": "WNXAI87654321",
          "nameDevice": "Bedroom Air Purifier",
          "nameAutoSwitch": "My Auto Switch"
        }
      ],
      "platform": "WinixPurifiers"
    }
  ]
}

If you're configuring the plugin manually or using HOOBS, you need to store your Winix password securely in the configuration file. To do this, you must first encrypt your password using the provided encrypt-password script.

1. Clone the repository:

You’ll need to clone this plugin's repository locally to run the encryption script. Make sure you have Node.js 20+ installed on your machine.

git clone https://github.com/regaw-leinad/homebridge-winix-purifiers.git
cd homebridge-winix-purifiers

2. Run the encryption command:

Use the following command in your terminal:

npm run encrypt-password <winix-password> <your-encryption-key>

Replace <winix-password> with your actual Winix account password and <your-encryption-key> with the key you plan to use.

3. Update your configuration:

The script will output your encrypted password. Copy the result and paste it into the password field in your config.json under the auth section:

{
  "auth": {
    "username": "your-email@domain.com",
    "userId": "f470ce5f-6b8e-44b4-a6db-b7f4d4c6f851",
    "password": "<encrypted-password>"
  }
}

This ensures that your password is securely stored within the configuration file.

Unfortunately, there's no way to directly migrate from the old plugin architecture to the new one. Please follow the Migration Guide in the Wiki:

Migrating from v1.x.x to v2.x.x.

If you're using HOOBS, you can install the plugin directly from the HOOBS interface. You will not be able to use the custom configuration UI, since it is not supported in HOOBS. You will need to use the manual configuration method. Please see this issue for more details on obtaining the required auth values. See Encrypting Your Password for instructions on encrypting your Winix password.

Getting error generating winix account from existing auth: NotAuthorizedException: Refresh Token has expired? Winix refresh tokens expire after 30 days. For now, you will need to generate a new refresh token by re-authenticating with Winix. Find the Reauthenticate with Winix button in the plugin config settings in the Homebridge UI, and sign in with your email and password. Work has started on a new feature to automate this process (branch).

Please see this issue for more details.

Try moving the purifier to a room with a different name, then move it back to the desired room. For example, if you have a room named “Bedroom” and a purifier named “Bedroom”, try moving the purifier to a room named "Living Room", then move it to "Bedroom".
