Thing you want to do

I heard that Tesla's API can be used unofficially, so I immediately touched it Since you can get vehicle information, let's get it with Python for the time being and notify Slack

Preparation

--See below for API documentation (unofficial)
https://tesla-api.timdorr.com/api-basics/authentication

--Authentication ID is as described below
https://pastebin.com/pS7Z6yyP

`Authentication ID`


TESLA_CLIENT_ID=81527cff06843c8634fdc09e8ac0abefb46ac849f38fe1e431c2ef2106796384
TESLA_CLIENT_SECRET=c7257eb71a564034f9419ee651c7d0e5f7aa6bfbd18bafb5c5c033b093bb2fa3

Operating environment, etc.

--Confirmed with Python 3.7 series (Windows) ――For the time being, I tried to make it work using GAE

Overview

--Authentication is ʻOAuth2Service --I don't want to embed ID / PASS, so make it a separate file and get it withconfig parser` --The structure of the data can be roughly understood by looking at the contents of resp. --Since the process to wake up the vehicle is not included, start it with the application etc. in advance and then execute the script (Since it does not include retry etc., it will fail and end)

script

`teslaapi_test.py`


def access_vehicle():
    import json
    from rauth import OAuth2Service #For TESLA API
    import configparser

    config = configparser.ConfigParser()
    config.read('config.conf')
    section = 'development'
    
    teslaID = config.get(section,'teslaID')
    password = config.get(section,'password')

    tesla = OAuth2Service(
        client_id = config.get(section,'client_id'),
        client_secret = config.get(section,'client_secret'),
        access_token_url = "https://owner-api.teslamotors.com/oauth/token",
        authorize_url = "https://owner-api.teslamotors.com/oauth/token",
        base_url = "https://owner-api.teslamotors.com/",
        )
    data = {"grant_type": "password",
        "client_id": config.get(section,'client_id'),
        "client_secret": config.get(section,'client_secret'),
        "email": teslaID,
        "password": password}

    session = tesla.get_auth_session(data=data, decoder=json.loads)
    access_token = session.access_token
    my_session = tesla.get_session(token=access_token)

    url = 'https://owner-api.teslamotors.com/api/1/vehicles/'
    vehicles = my_session.get(url).json()['response'][0]
    mycar = vehicles['id_s']

    return mycar,my_session

def get_vehicle_status():
    import json
    import datetime
    from rauth import OAuth2Service #For TESLA API

    mycar,my_session = access_vehicle()

    url_vehicle_state = "https://owner-api.teslamotors.com/api/1/vehicles/{:}/vehicle_data".format(mycar)
    resp = my_session.get(url_vehicle_state).json()

    return resp

Create the following as a configuration file

`config.conf`


[development]
#tesla
teslaID = 'User ID'
password = 'password'
client_id = '81527cff06843c8634fdc09e8ac0abefb46ac849f38fe1e431c2ef2106796384'
client_secret = 'c7257eb71a564034f9419ee651c7d0e5f7aa6bfbd18bafb5c5c033b093bb2fa3'

Slack notification

Notifications are easy using Incoming-webhook. https://api.slack.com/messaging/webhooks#posting_with_webhooks

`slack notification`


import slackweb

slack = slackweb.Slack(url="Webhook URL")
slack.notify(text="Cruising distance: {}[km]".format(resp['response']['battery_range'] * 1.60934))

Since the distance unit is [mi], it is converted to [Km].

The result looks like this

afterwards

In order to get the status and send the notification periodically, I will deploy it to GAE and trigger it with cron, or add Wake-Up processing so that it can be obtained even if the vehicle is Sleep.
