Fade effect when power on/off single segment

Issues
1

Hi,

I have an home setup where an ESP32 control 5 segments which are 5 rooms main lights.

When i use the default fade effect in segment page as transition for power on/off, the fade effect works for each segment using the dedicated power button. After few hours it stops working, and the strips turns on/off without effect.

This happens immediately and not after time if i select any effect apart the default one, fade.

For get it back fading i’ve to restart WLED.

I’m running last stable release, 16.0.1, but it do the same thing with all the previous version.

When the single segment not fade, if i use the general power button in the top bar it fade correctly, obviously all of the segments together.

I think this is a bug, but i cannot find anything related on the issues page on Git.

Thanks to anyone have info on this.

tested this, works perfectly fine. are you sure nothing changes the transition to something other than fade?

I also checked code and fixed segment opacity/brightness transitions for all transition types.

I simply select another fade effect then turn on/off single segment.

The segment turns off instantly without any fade effect.

For example, the default fade effect works for few hours, but if i select twinkle effect it simply turns on/off without any effect.

Do you think i’ve to try a clean reprogramming of the esp32? I use wled on this from the 14.x upgrading it, maybe a fresh install can solve?

@dedehai your fix solved the issue, i’ve found by my side on HA, an automation that i use rarely which turns on a partial section of a segment, in this call the lack of {“tt”:12} in the rest command to the api reset to 0 the TT value.
Mea culpa, solved the “few hours mistery”, my mistake.
Anyway now we can freely select any fade effect for single segment and works like a charm.
