In fact, KOReader uses sysfs on newer devices:

Aura One: https://github.com/koreader/koreader...device.lua#L74
H2O2: https://github.com/koreader/koreader...evice.lua#L126
H2O2r2: https://github.com/koreader/koreader...evice.lua#L143
Clara: https://github.com/koreader/koreader...evice.lua#L195
...

OP could check if the aura hd has a similar node under /sys/class/backlight and explore its attributes. See https://github.com/koreader/koreader...ment-437626445
