I'm net at hotkeys, so maybe you can lend me a hand

Hi, I'm new at overriding default hotkeys, so I'm hoping you can lend me a hand. I'm attempting to remap XF86MonBrightnessUp & XF86MonBrightnessDown to run the commands "lumeus +5%" and "lumeus -5%" respecitively. (Lumeus available here btw https://github.com/siiptuo/lumeus). Basically, I'm using XFCE and I want there to be 20 monitor brightness jumps instead of 10. Setting this in keyboard-shortcuts doesn't do anything, unfortunately.

I've created the config file in /etc/triggerhappy/triggers which consists of

<event name> <event value> <command line>
XF86MonBrightnessUp 1 lumeus +5%
XF86MonBrightnessUp 2 lumeus +5%
XF86MonBrightnessDown 1 lumeus -5%
XF86MonBrightnessDown 2 lumeus -5%

I'm fairly certain I've done something wrong because I'm getting this error when I use the sudo thd command:

No input device files or command pipe specified.

Anything you can tell me would be very helpful!
