WLED on a Sonoff L1 / Spider Z

Hi,

I flashed WLED on a Sonoff Spider Z / L1, which was working fine. Now, when I turn on the controller all LED’s are white and turning them on or off does not change anything. I tried different settings for GPIO and the output, but none these seem to work.

I also tried to set the GPIO’s to 1, 3, 13 as described in the Tasmota template and on Reddit, but the LED’s do not react on any command: https://www.reddit.com/r/WLED/comments/zlw1cz/gpios_for_sonoff_l1/

Also the whole strip was working on Tasmota as described here: Sonoff L1 LED Strip Configuration for Tasmota

Any Idea which GPIO i have to use? What else do I need to set up to get it working?

Thanks,

Dominik
