Troubleshooting
The most common error messages and connection problems, and how to fix them.
Connection and adapter start
- Why doesn't the adapter start after an update, or why does it stop responding?
- Why does the adapter stop working after a WLED firmware update, or segments only work on one device?
- Why is WLED shown as offline after a restart or update and takes a long time to reconnect?
- Why do all WLED devices show red or offline, or the ESP crashes?
- What do I do about multiple adapter processes, "already running" or onUnload errors?
Commands and scripts have no effect
- Why isn't the on/off state updated?
- Why doesn't my script set ps or on, or why does WLED ignore the commands?
- Why do several commands in quick succession lead to ETIMEDOUT?
- Why does ps jump to -1 or not show the selected preset?
- Why do some LEDs stay on after switching off?
- Why does the cct state have no effect?
Colors and visualisation
- Why does the color jump back and forth, or the transition time go back to 7?
- Why doesn't the HEX color work, or work wrongly (white channel, after a WLED update)?
- Why does the color picker in VIS switch WLED off?
- Why does the VIS 2 editor freeze when I pick seg.0.fx in the drop-down?
