BMW i Remote API

A reverse engineered interface for the BMW i3 Electric Car, created initially by Terence Eden, with some code modified by Quentin Stafford-Fraser.

Description

These API calls are designed to allow you to interact with your BMW i3. They were reverse engineered from the official BMW i Remote Android app.

Your use of these API calls is entirely at your own risk. They are neither officially provided nor sanctioned.

THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.

Servers

There are three API servers.

  • https://b2vapi.bmwgroup.cn:8592 China
  • https://b2vapi.bmwgroup.us USA
  • https://b2vapi.bmwgroup.com Europe / Rest of World

Authorisation

In order to authenticate against the API you will need to be registered on BMW's Connected Drive service.

You will need:

  1. Your ConnectedDrive registered email address.
  2. Your ConnectedDrive registered password.
  3. The i Remote API Key.
  4. The i Remote API Secret.

You can get the i Remote details from either decompiling the Android App or from intercepting communications between your phone and the BMW server. This is left as an exercise for the reader ☺

Firstly, we use Basic authentication. That means taking the API Key and Secret and Base64 encoding them.

So key:secret becomes a2V5OnNlY3JldA==

We also need to send the following parameters as

  • Content-Type: application/x-www-form-urlencoded
 grant_type=password
&username=whatever%40example.com
&password=p4ssw0rd
&scope=remote_services+vehicle_data

Here's how to do it with curl:

curl \
   -H "Authorization: Basic a2V5OnNlY3JldA==" \
   -H "Content-Type: application/x-www-form-urlencoded" \
   -d "grant_type=password&username=whatever%40example.com&password=p4ssw0rd&scope=remote_services+vehicle_data" \
   "https://b2vapi.bmwgroup.com/webapi/oauth/token/"

If everything has worked, you should get back the following JSON:

{
  "access_token": "RCQ1hLP4AFaUBW9BjcPUN3i4WgkwF90R",
  "token_type": "Bearer",
  "expires_in": 28800,
  "refresh_token": "7WgKmEJ2kD1ydl9Hefp01eS8qDGzKnzjeORpA6vtsoFIEanz",
  "scope": "vehicle_data remote_services"
}

You must include

  • Authorization: Bearer RCQ1hLP4AFaUBW9BjcPUN3i4WgkwF90R

in your headers with every request.

The expires_in is in seconds - giving you 8 hours before you have to renew the token.

I've no idea what the refresh_token is for. Once the access_token expires, you can simply re-authenticate and gain a new one.

API

You must include

  • Authorization: Bearer RCQ1hLP4AFaUBW9BjcPUN3i4WgkwF90R

in your headers with every request.

Get Vehicle Data

  • /webapi/v1/user/vehicles/
    • Remember to include the Authorization: Bearer header.

Response

Returns a list of entries, one per registered vehicle.

The most important thing here is the VIN - Vehicle Identification Number. You'll need that for all the other API calls as well as the Authorization Bearer.

Sending information to the car

Sending information to the car is slightly complicated.

Your app communicates with the API, the API then communicates with the car's 3G modem, then you have to wait for a response.

If your car is in poor coverage, you can expect significant latency. Often much higher than a typical timeout will allow for.

At a basic level, you can just send a request - for example to lock the doors, or set off-peak charging.

Get Request status

Shows the status of a POSTed request

  • /webapi/v1/user/vehicles/:VIN/serviceExecutionStatus?serviceType=:SERVICE
    • Where :VIN is your vehicle's VIN.
    • Remember to include the Authorization: Bearer header.

Response

{
   "executionStatus":{
      "serviceType":"DOOR_LOCK",
      "status":"EXECUTED",
      "eventId":"123456789012345AB1CD1234@bmw.de"
   }
}

Values

Valid statuses are:

  • DELIVERED
  • EXECUTED
  • INITIATED
  • NOT_EXECUTED
  • PENDING
  • TIMED_OUT

The following are valid :SERVICE types, but may not be supported by your vehicle.

POST a command

Instructs the car to perform an action.

  • /webapi/v1/user/vehicles/:VIN/executeService
    • Where :VIN is your vehicle's VIN.
    • Remember to include the Authorization: Bearer header.

Available Commands

These commands are all available via the API, but may not be supported by your vehicle.

These are just what I've discovered so far.

Data must be POSTed to the server.

Initiate Charging

If the vehicle is plugged in, but not charging (due to an off peak setting?) it is possible to force the car to charge.

  • serviceType=CHARGE_NOW

Start Climate Control

This will activate climate control within your vehicle.

It appears to be limited to the last temperature you set when you were in the car. I can't find a way to instruct the car to reach a specific temperature.

  • serviceType=CLIMATE_NOW

Lock the doors

Performs central locking.

  • serviceType=DOOR_LOCK

Unlock the doors

This will unlock all the doors on your vehicle.

Please use extreme caution when sending this command. Ensure that you are in sight of the vehicle and are able to lock it if needed.

  • serviceType=DOOR_UNLOCK

If you recievce an error after DOOR_UNLOCK that looks like {"error":{"code":500,"description":"(SmartPhoneUtil-A-2013) Action is forbidden. secretKnowledge is missing but required!"}}

An addition field must be included

  • serviceType=DOOR_UNLOCK
  • bmwSkAnswer=BMW_ACCOUNT_SECURITY_QUESTION_ANSWER

Flash the headlights

If you can't find the vehicle, or need to illuminate something in its vicinity, you can briefly activate the headlights.

  • serviceType=LIGHT_FLASH&count=2
    • I assume that count relates to the number of seconds to keep the light on?

Charging Schedule

Set the peak / off peak charging schedule.

  • serviceType=CHARGING_CONTROL
    • Additional data needs to be sent as parameter data in JSON format. The data itself is the same as returned by Get Charging Times.
    • Instead of weeklyPlanner twoTimesTimer can be used. Format of data currently unknown.
