Just joined this community and a happy and grateful user of WLED. I’ve got two units working (esp8266 simply connected to individually addressable WS2812B strip) but whatever I’ve tried, even repeating the exact wiring, I’m unable to get other units to work. I’ve used esp8266 and esp32, with a variety of WS2812B strips, with a variety of wiring options. In all cases the WLED web app is accessible both as its own AP (http://126.96.36.199) and post-config on my home network. Its just the LEDs don’t light up at all. The power button in the AP works in the sense it turns the esp8266’s own blue LED on and off. Any ideas?
This is the basic wiring scheme: tried D2 and D4 for the data line.
