The voltage level on data input is too low! ESP Evaluation Boards have 3,3 level outputs, most LED-stips needs 5V logiclevel. You will need levelshifter, like SN74LVC1T45, or a Controller with a levelsifter onboard.  
That’s my solution: [https://wled.discourse.group/t/once-more-esp8266-based-wled-controller/11130](https://wled.discourse.group/t/once-more-esp8266-based-wled-controller/11130)
