A quick script to turn my USB christmas tree lights on and off. Runs on Raspberry Pi.
To use, clone and edit the service file as needed, copy it to /lib/systemd/system, refresh systemd and enable the service.
It's not elegant. All its doing is turning the usb ports on and off. On the other hand, this script works for any usb-powered device that needs to be turned on or off.
Note that an easy way to automate the trigger is to make a shortcut on an iOS device that requests the /on, /off, or /toggle endpoints. For example, my tree turns on when I stop my morning alarm.
