Hi, my previous setup: white (grnd) cable from the led connected to ESP (grnd) with PS and backup data blue cable. Red cable (pos) to ESP with PS and green to green GPIO D4 on ESP. LED setting GPIO4.
Correct, I’m using WLED controller, I’m using GPIO4 and changed on the controller too. LED needs 12V and not 5V and they don’t need level shifter according to BTF.
