I wanted to replicate this project for in my home. I bought all the parts and assembled them. But for some reason not one LED in the strip (5m WS2813) is lighting up. I have a 5V power supply, and a Logic lever converter between the NodeMCU v3 (Lollin) and the strip. The strip is getting power (5 volt at the beginning and slightly less at the end, measured with multimeter). The NodeMCU has internet connection, and I connected it to a cloudMQTT server from wich I can send it messages. This all works perfectly, because in the terminal I see the message coming in and displaying for example:
I have tried different pins, with or without 470Ohm resistor between the LL0-convertor's HV output and strip data cable (btw, I have the strip with a backup data line, but I read that I shouldnt connect that anywhere, so that is not plugged in).
The code used is a direct copy, just with my own MQTT and wifi settings.
Any clues what is going on? Faulty LED Strip? Just came in from the factory, haven't even seen it turn on :/ Or am I missing something else? If more info is needed please let me know and I'll provide it.
Okay, so here goes.
