Tesla JSON API

View Documentation

This is unofficial documentation of the Tesla JSON API used by the iOS and Android apps. The API provides functionality to monitor and control the Model S (and future Tesla vehicles) remotely. The project provides both a documention of the API and a Ruby library for accessing it.

If any folks at Tesla are reading this, I'd love to help coordinate a developer program for your APIs. If there's any way I can be helpful, please feel free to get in contact. Also, I'd love to be in the beta firmware program 😉

Ruby Gem

This gem provides a basic wrapper around the API to easily query and command the car remotely. It also provides access to the streaming API and a means to process data coming from it.

Installation

Add this line to your application's Gemfile:

gem 'tesla_api'

Or install it yourself:

gem install tesla_api

Usage

Here's a quick example:

require 'tesla_api'

tesla_api = TeslaApi::Client.new(email, client_id, client_secret)
tesla_api.login!(password) # Or tesla_api.token = token if you have an existing token.
model_s = tesla_api.vehicles.first # => <TeslaApi::Vehicle>

model_s.wake_up
model_s.auto_conditioning_start unless model_s.climate_state["is_auto_conditioning_on"]

model_s.set_charge_limit(90)
model_s.charge_start

charge_state = model_s.charge_state
puts "Your Model S is #{charge_state["charging_state"]} " +
     "with a SOC of #{charge_state["battery_level"]}% " + 
     "and an estimate range of #{charge_state["est_battery_range"]} miles"
