New to WLED - wow great project. I tested this with a DFRobot Firebeetle ESP32 and it seems to work fine. Maybe you want to add that to the HCL? This device specifically: FireBeetle ESP32 IoT Microcontroller - DFR0478 | DFRobot Electronics
If there are any specific tests you’d like, I can arrange to do those when I get some strings for the garden.
