So i connect a 5 meters of WS2815 to an esp-01 through a data voltage converter and it always appears fully lit when the esp brightness slider is at halfway. I expect it being half lit when the slider is halfway, and increasing in brightness when moved forward. It does decrease in brightness when moved backwards from the halfway position, but does not increase when moved forward.
Not an issue personally as i know it behaves so, and has behaved so for a year or more. Just would like to know the solution to make all the slider count.
