Quick and dirty way to use a cheap bluetooth selfie remote on a linux server (like a raspberry pi) to control lifx lights
ACTION=="add", SUBSYSTEM=="input", ATTRS{name}=="AB Shutter3 ", TAG+="systemd", PROGRAM="/bin/systemd-escape -p --template=lifx-remote@.service $env{DEVNAME}", ENV{SYSTEMD_WANTS}+="%c"
The full paths of the file are:
/etc/udev/rules.d/99-lifx-keyboard.rules
/etc/systemd/system/lifx-remote@.service
/usr/local/bin/lifx-remote.py
Install the python dependancies lister in requirements.txt using pip.
If you have multiple remote, you could filter them in the udev rule.
It should work with multiple bulb, but I haven't tested that.
