The brightness of the LED, possible values are in the range 0 - 255
### Methods:
#### `SetMode(u) → ()`
Set the mode to the given mode enum value from libratbag
#### `SetColor((uuu)) → ()`
Set the color to the given uint triplet (RGB)
#### `SetEffectRate(u) → ()`
Set the effect rate in Hz, possible values are in the range 100 - 20000
#### `SetBrightness(i) → ()`
Set the brightness, possible values are in the range 0 - 255
For easier debugging, objects paths are constructed from the device. e.g.
`/org/freedesktop/ratbag/button/event5/p0/b10` is the button interface for
button 10 on profile 0 on event5. The naming is subject to change. Do not
