This is an open source Python 3 library to control an Elgato Stream Deck directly, without the official software. This can allow you to create your own custom front-ends, such as a custom control front-end for home automation software.
I've used the reverse engineering notes from this GitHub repository to implement this library. Thanks Alex Van Camp!
Initial StreamDeck Mini support added by Aetherdyne.
StreamDeck XL support assisted by Pointshader.
Working - you can enumerate devices, set the brightness of the panel(s), set the images shown on each button, and read the current button states.
Currently the following StreamDeck product variants are supported:
- StreamDeck Original
- StreamDeck Mini
- StreamDeck XL
The library core has no special dependencies, but does use one of (potentially) several HID backend libraries. You will need to install the dependencies appropriate to your chosen backend.
The included example requires the PIL fork "Pillow", although it can be swapped out if desired by the user application for any other image manipulation library.
To install all library dependencies at once, run:
pip install -r requirements.txt
The default backend is the HIDAPI Python library, which should work across the three major (Windows, Mac, Linux) OSes.
Install the library via pip:
pip install streamdeck
Alternatively, manually clone the project repository:
git clone https://github.com/abcminiuser/python-elgato-streamdeck.git
The following script has been verified working on a Raspberry Pi (Model 2 B) running a stock Debian Stretch image, to install all the required dependencies needed by this project:
# Ensure system is up to date, upgrade all out of date packages
sudo apt update && sudo apt dist-upgrade -y
# Install the pip Python package manager
sudo apt install -y python3-pip
# Install system packages needed for the Python hidapi package installation
sudo apt install -y libudev-dev libusb-1.0-0-dev
# Install dependencies
pip3 install hidapi
# Add udev rule to allow all users non-root access to Elgato StreamDeck devices:
sudo tee /etc/udev/rules.d/10-streamdeck.rules << EOF
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0fd9", GROUP="users"
EOF
# Install the latest version of the StreamDeck library via pip
pip3 install streamdeck
# Alternatively, install git and check out the repository
#sudo apt install -y git
#git clone https://github.com/abcminiuser/python-elgato-streamdeck.git
Note that after adding the udev rule, a restart will be required in order for
it to take effect and allow access to the StreamDeck device without requiring
root privileges.
