bmwcdapi.py

https://github.com/jupe76/bmwcdapi

Bmwcdapi.py is a python script to query various informations about your car from the BMW ConnectedDrive portal in conjunction with obenhab.

I'm using it for a BMW i3, but should work with other types as well.

The techniques to access the ConnectedDrive portal were taken from https://github.com/sergejmueller/battery.ebiene.de

Prerequisites

You'll need the credentials (username / password) for a ConnectedDrive login and the 17 chars long vehicle ident number (VIN) of your car. Furthermore you need a running openhab installation and python 3.x . The script has been tested with openhab2.

Installation

Copy bmw.rules and bmw.items in the according openhab dirs.

Edit Bmw_Username, Bmw_Password and Bmw_Vin placed in bmw.items to hold your credentials and the VIN of your car.

If your script dir is not /etc/openhab2/scripts than you need to edit bmw.rules.

Copy bmwcdapi.py to the openhab script dir. If the script is running on another computer than your openhab installation, than you need to adjust OPENHABIP.

Edit your sitemap to visualize the items.

Usage

The script is called every 30 min to update the values. You can adjust the timespan in bmw.rules (be nice to the ConnectedDrive portal and don't hammer the server) With the switch Bmw_ForceUpdate you could initiate an immediate update.

To execute services like to climate the car, call the bmwcd api.py with the commandline parameter --execservice and the appropriate service, i.e. bmwcdapi.py --execservice climate
