A CLI application and Go library to control your Elgato Stream Deck on Linux.

If you're looking for a complete Linux service to control your StreamDeck, check out Deckmaster, which is based on this library.

Make sure you have a working Go environment (Go 1.11 or higher is required). See the install instructions.

To install streamdeck, simply run:

go get github.com/muesli/streamdeck 

On Linux you need to set up some udev rules to be able to access the device as a regular user. Edit /etc/udev/rules.d/99-streamdeck.rules and add these lines:

SUBSYSTEM=="usb", ATTRS{idVendor}=="0fd9", ATTRS{idProduct}=="0060", MODE:="666", GROUP="plugdev" SUBSYSTEM=="usb", ATTRS{idVendor}=="0fd9", ATTRS{idProduct}=="0063", MODE:="666", GROUP="plugdev" SUBSYSTEM=="usb", ATTRS{idVendor}=="0fd9", ATTRS{idProduct}=="006c", MODE:="666", GROUP="plugdev" SUBSYSTEM=="usb", ATTRS{idVendor}=="0fd9", ATTRS{idProduct}=="006d", MODE:="666", GROUP="plugdev" SUBSYSTEM=="usb", ATTRS{idVendor}=="0fd9", ATTRS{idProduct}=="0080", MODE:="666", GROUP="plugdev" 

Make sure your user is part of the plugdev group and reload the rules with sudo udevadm control --reload-rules. Unplug and replug the device and you should be good to go.

Control the brightness, in percent between 0 and 100:

streamdeck-cli brightness 50 

Set an image on the first key (from the top-left):

streamdeck-cli image 0 image.png 

Clear all images:

streamdeck-cli clear 

Reset the device:

streamdeck-cli reset
