Tesla JSON API
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 to for accessing it.
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_apiUsage
Here's a quick example:
require 'tesla_api'
tesla_api = TeslaApi::Client.new(email, password, client_id, client_secret)
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"Copyright
