A small web app that displays sensor data and controls a MOVIDRIVE Antriebsumrichter (traction converter) of SEW EURODRIVE connected to the Raspberry Pi with the help of a controller area network (CAN) bus.



In order to install CANberry just create a virtual environment and use pip:

pip install canberry


Create a configuration file .canrc with following content in your home directory:

interface = socketcan
channel = can0

identifier = 16
# Is server externally visible? 'true' or 'false'
external = true
# Run the server in debug mode? 'true' or 'false'
debug = false

The identifier is the default target address.


Running an externally visible server in debug mode is not recommended!



  • Create a virtual environment virtualenv venv and activate it with source venv/bin/activate.
  • Install all dependencies with pip install -r requirements.txt.
  • Run python develop to install CANberry in your virtual environment.
  • Run canberry from the command line to start the web application. Try canberry -h for help on more options.
