Not used LEDs are on after some time #3243

The Problem

I have a LED Ring of 16 to ilkuminate a watermeter and prevent shadows. That works good excrpt for some reflections that i optimized by using only the first 12 LEDs. I cused the config and set the number to 12. At first, this works and the remaining four stay off. After some time all LEDs are on and cause wrongly detected values due to reflections. I have to power off and power on the watermeter to reset them as a reboot does not help.

I guess it is caused by some glitch that forwards configuration data to the remaining LEDs and normally they are not configured which means they will also not be turned off again. This is the bug part. It might be in the used library to generate the configuration bitstream of the LEDs.

Now thr feature request part: It wouls be great if there would be an option to disable certain LEDs of a strip. Maybe a simple bitmask of the length of the strip would be enough.

Currently I would need to modify the strip on hardware level by cutting off LEDs or by putting light-absorbing tapebon them.

If you increase CamGainceiling, you can reduce the LED intensity and thereby mostly eliminate the reflections.

Which LED type do you use, WS2812, WS2812B or WS2813? try this version: AI-on-the-edge-deviceupdate3261merge(fb37467).zip
