Reduce brightness on all kobo devices / challenge for developers

Hi guys,

First sorry for my bad english, Im' french.

I've got a Glo (not HD) on which I've added a resistor in order too reduce the brightness since 2013 and all is ok still today after 6 years; I was the first person to ask the question and Yok and others guys have found a solution here : https://www.mobileread.com/forums/sh...=200706&page=7 ).

I've got a second kobo (aura HD) and the brightness is too high...

So I've got a question : is there a way with a plugin too reduce brightness on all Kobo devices ? if not, a good solution would be to create a plugin that can divide the setting by 2 or 3 or why not 10, in order to reduce brightness under 1% like 0.1%, 0.2%, etc.
If the brightness slider does not accept a setting under 1%, another solution coud be to mislead the value send to the LEDS (we set 10% on the slider but the real value send is 1%, 9% send 0.9%, etc).

Developers : do you see a solution :chinscratch: , it could be a good challenge, no ?

A good add-on is nightmode, it can be found here : https://github.com/gtalusan/kobo-nig...de_build13.zip but it doesn't reduce the level of the leds.
