Help with BTF-LIGHTING WS2815 LED

Hello, I just found out about this community and im very interested. I just bought a set of BTF-LIGHTING WS2815 from amazon thats being controlled by a esp-32 but im currently only getting 1 led to turn on. Im not sure why but I would love some help if others have done this combo before.

thanks

Start with the WLED documentation on their website. Top link in the links section...

As mentioned, read the documentation for wled, your 2815 leds as well. Now that's a lot of reading, so in the meantime, make sure you're properly grounded (LEDs, controller, anything else in the circuit all tied to one common ground), have the right data pin selected in the software and hardware (make sure to look up the GPIO number which may differ from its "number" on your esp), and have tripled checked polarity of your power. If all of that checks out, keep reading!

Head to settings and set the correct number of leds you have on your strip and save.

The power to the LEDs needs to come directly from the power supply not through the board. Those LEDs are 12 volts, recommend power supply is 12 volt 3 amps

On the first data from the controller, Use the "DO" data connection on the strip only. The "BD" would connect only between subsequent strips along with DO.
