# Remote Control of PSA car
### This is a python program to control a psa car with connected_car v4 api. Using android app to retrieve credentials.
I test it with a Peugeot e-208 but it works with others PSA vehicles (Citroen, Opel, Vauxhall, DS).

With this app  you will be able to :
 - get the status of the car (battery level for electric vehicle, position ... )
 - start and stop the charge
 - set a charge threshold to limit the battery level to a certain percentage
 - set a stop hour to charge your vehicle only on off-peak hours
 - control air conditioning
 - control lights and horn if your vehicle is compatible (mine isn't) 
 - get consumption statistic
 - visualize your trips on a map
 
The api is documented [here](https://developer.groupe-psa.io/webapi/b2c/quickstart/connect/#article) but it is not totally up to date, and contains some errors. 


## I. Get credentials
We need to get credentials from the android app.
We will retrieve these informations:
 - client-id and client-secret  for the api
 - some url to login

1.1 Download the app on your computer, the original MyPeugeot app can be downloaded [here](https://apkpure.com/fr/mypeugeot-app/com.psa.mym.mypeugeot) for example.

1.2 Install requirements :

- On debian based distribution you can install some requirement from repos: 
 
 ```sudo apt-get install python3-typing-extensions python3-pandas python3-plotly python3-paho-mqtt  python3-six python3-dateutil python3-brotli  libblas-dev  liblapack-dev gfortran python3-pycryptodome```
    
- For everyone :
      ```pip3 install -r requirements.txt```

1.3  run the decoder script : ```python3 app_decoder.py <path to my apk file>```
  
    mypeugeot email: <write your mypeugeot email>
    mypeugeot password: <write your mypeugeot password>
    What is the car api realm : clientsB2CPeugeot, clientsB2CDS, clientsB2COpel, clientsB2CVauxhall
    clientsB2CPeugeot
    What is your country code ? (ex: FR, GB, DE, ES...)
    FR
    save config change

    Your vehicles: {'VINNUBMER': {'id': 'vehicule id'}}

1.4 If it works you will have VIN of your vehicles and there ids in the last line. The script generate a test.json file with all credentials needed.

 ## II. Use the app
  
            
  1. start the app:
        
     Start the app with charge control enabled :

     ``python3 server.py -f test.json -c charge_config1.json``
     
     At the first launch you will receive a SMS and you will be asked to give it and also give your pin code (the four-digit code that your use on the android app).
     If it failed you can remove the file otp.bin and retry.
   
     You can see all options available with :
    ``python3 server.py -h``


  2. Test it 
  
    2.1 Get the car state :
    http://localhost:5000/get_vehicleinfo/YOURVIN
    
    2.2 Stop charge (only for solution 1)
    http://localhost:5000/charge_now/YOURVIN/0
    
    2.3 Set hour to stop the charge to 6am
    http://localhost:5000/charge_control?vin=yourvin&hour=6&minute=0 
    
    2.4 Change car charge threshold to 80 percent
    http://localhost:5000/charge_control?vin=YOURVIN&percentage=80 

    2.5 See the dashboard (only if record is enabled)
    http://localhost:5000

  3. Dashboard and stats (Beta)
     
     You can add the -r argument to record the position of the vehicle and retrieve this information in a dashboard.

     ``python3 server.py -f test.json -c charge_config1.json -r``
    
     You will be able to visualize your trips, your consumption and some statistics:

    You can add an api key for  https://home.openweathermap.org/ in your config file.
    In the future version of the dashboard you will be able to see your consumption vs exterior temperature.  
    
## API documentation
The api documentation is described here : [api_spec.md](api_spec.md).
You can use all functions from the doc, for example :
```myp.api().get_car_last_position(myp.get_vehicle_id_with_vin("myvin"))```
## More information
To analyse the traffics between the app and psa server, you can use mitmproxy.
You will need the client certificate present in the apk at asssets/MWPMYMA1.pfx
```bash
# decrypt the pfx file (there is no password)
openssl pkcs12 -in MWPMYMA1.pfx -out MWPMYMA1.pem -nodes
```
Then you can use mitmproxy for example:

```
mitmproxy --set client_certs=MWPMYMA1.pem
```
