Tesla Accessory

Example config.json:

{
  "accessories": [
    {
      "accessory": "Tesla",
      "name": "Model 3",
      "vin": "5JJYCB522AB296261",
      "refreshToken": "eyJhbGciOiJSUzI1…",
      "password": "<optional, only needed for keyless driving>",
      "waitMinutes": 1
    }
  ]
}

Exposes lock services for doors, trunk, and front trunk. Also exposes an on/off switch for climate control, and charge state.

If you define a value for password, you can also enable keyless driving by turning on the "starter" switch.

If you define a value for waitMinutes, you can control the amount of time the plugin will wait for the car to wake up. The default is one minute.

If you use the example above, you would gain Siri commands like:

• "Unlock the Model 3 Doors" (unlock the vehicle)
• "Open the Model 3 Trunk" (pop the trunk)
• "Open the Model 3 Front Trunk" (pop the frunk)
• "Open the Model 3 Charge Port" (open the charging port)
• "Turn on the Model 3 Climate" (turn on climate control)
• "Turn on the Model 3 Defrost" (turn on maximum defrost mode)
• "Turn on the Model 3 Sentry Mode" (turn on sentry mode)
• "Turn on the Model 3 Charger" (begin charging even if outside your schedule)
• "Turn on the Model 3 Connection" (wake the car up so you can ask if it's locked, etc.)
• "Turn on the Model 3 Starter" (enable keyless driving, requires password)

Important Note: The Home app will allow you to customize the default names of these services. You may be tempted to, for instance, change your "Model 3 Front Trunk" service to just "Front Trunk" so you can say "Open the Front Trunk". Don't do this! The names of these services are essentially global and live in a giant pool of names. Siri will get confused unless every service has an easily distinguished name.

You may disable various services using additional boolean configuration settings. See config.schema.json for more information.

Generating a Refresh Token

Tesla has recently (early 2021) updated their OAuth authentication system as part of adding support for MFA tokens. Tesla API access requires a "refresh token" which is tricky to get. There are some apps available that can help with this, check out this list. I have personally used the macOS app "Auth app for Tesla" (linked via that site) and it worked for me.

Once you get a refresh token using an app (it's very long), you can paste it into your plugin configuration above.

NOTE This plugin used to accept an authToken property which was intended to be an optional refresh token. If you have one already, you can just paste that token in the refreshToken property. The authToken property is no longer used, since the name refreshToken is more accurate and sets the token apart from OAuth "access tokens" which are only good for 8 hours.

Multiple Vehicles

Have a garage full of Teslas? Well you're in luck Mr. Musk, because you can easily add all of them to HomeKit by creating a separate accessory for each one distinguished by their unique VIN numbers:

{
  "accessories": [
    {
      "accessory": "Tesla",
      "name": "Model 3",
      "vin": "5JJYCB522AB296261",
      "refreshToken": "…"
    },
    {
      "accessory": "Tesla",
      "name": "Model X",
      "vin": "1XSYCA2224A216162",
      "refreshToken": "…"
    }
  ]
}

HomeLink

For vehicles with HomeLink support, the plugin allows you to enable the feature to send a HomeLink signal from the car. This is disabled by default. To enable the feature, you may use the UI (check the Enable HomeLink Service to enable it) or add a setting in the accessory section for the vehicle. You also must provide a latitude and longitude value for the HomeLink device.

Once that is done, you can issue commands like "Open the Model 3 HomeLink". If you don't have any other garage doors in HomeKit, you may also be able to just say "Open the garage door" since it's exposed as a true garage door service.

{
  "accessories": [
    {
      "accessory": "Tesla",
      "name": "Model 3",
      "vin": "5JJYCB522AB296261",
      "refreshToken": "…"
      "enableHomeLink": true,
      "latitude": "37.492655",
      "longitude": "-121.944644"
    }
  ]
}

Charge Level

The car can supply the current charge level of the battery as a percentage. This will only update if the car is awake. Asking Siri about your car's charge level will not wake up the car (because Siri asks a lot in the background). So you'll have to issue a write command like "Turn on the Model 3 Connection" first.

The Charge Level can be disabled in either your Homebridge UI or by adding the following to the car's accessory section.

"disableChargeLevel": true

Development

You can run Rollup in watch mode to automatically transpile code as you write it:

  npm run dev
