Carwings

carwings is a Go package and command-line tool providing access to the Nissan Leaf Carwings API.

Through the Carwings API you can ask your vehicle for the latest data, see current battery and charging statuses, see the current climate control state, start or stop climate control remotely, and remotely start charging.

Command-line tool

The carwings tool can be installed with:

go install github.com/joeshaw/carwings/cmd/carwings@latest

Run carwings by itself to see full usage information.

To update vehicle information:

carwings -username <username> -password <password> -region <region code> update

To get latest battery status:

carwings -username <username> -password <password> -region <region code> battery

This will print something like:

Logging into Carwings...
Getting latest retrieved battery status...
Battery status as of 2017-08-06 15:43:00 -0400 EDT:
  Capacity: 240 / 240 (92%)
  Crusing range: 114 miles (107 mi with AC)
  Plug-in state: not connected
  Charging status: not charging
  Time to full:
    Level 1 charge: 8h30m0s
    Level 2 charge: 3h0m0s
    Level 2 at 6 kW: 2h30m0s

For some people the username is an email address. For others it's a distinct username.

The regions are:

Nissan Region	Carwings Region Code
USA	NNA
Europe	NE
Canada	NCI
Australia	NMA
Japan	NML

Config values can be provided through environment variables (such as CARWINGS_USERNAME) or in a ~/.carwings file in the format:

username <username>
password <password>
region NA

Server mode

When carwings server is run, an HTTP server is started with endpoints for retrieving battery and climate info, and for starting charging and toggling the climate control system. This can be handy for building home automation workflows. I use this with IFTTT so that I can use the Google Assistant to start warming up my car.

The endpoints are:

GET /battery
GET /climate
POST /charging/on
POST /climate/on
POST /climate/off

The POST endpoints take no request body.

Carwings protocol

Josh Perry's protocol reference was incredibly helpful for the development of this library.

Josh also has an implementation in Javascript: https://github.com/joshperry/carwings

Jason Horne has a Python implementation: https://github.com/jdhorne/pycarwings2

Phil Cole has taken it, ported it to Python 3, and is carrying it forward: https://github.com/filcole/pycarwings2

Guillaume Boudreau has a PHP implementation: https://github.com/gboudreau/nissan-connect-php

Scott Helme created a Javascript Alexa skill: https://github.com/ScottHelme/AlexaNissanLeaf

Tobias Westergaard Kjeldsen has created a Dart library for carwings as well as an Android app.

A new North America-only API is being tracked in issue #3, and more information is available there.
