Does anyone know what kind of IC is used in the govee H619? [Govee RGBIC LED Strip Lights With Protective Coating](https://us.govee.com/products/govee-rgbic-wi-fi-bluetooth-led-strip-lights-with-protective-coating) It doesn’t say on the IC and I can’t seem to control the strip with any of the LED types in WLED. Whichever one I choose, the strip does either nothing, goes full white or starts flickering. I’m using a ESP32. ---

Ok so to answer my own question. The IC is a WS281x type. I just had to use a level shifter to get the led strip to work. It did only work when I used GPIO 2 on the ESP32 though and I still have some flickering. ---

What shifter are you using? Make sure you have no floating inputs and a bypass capacitor. You should be able to use any valid GPIO on the ESP32, try #4,13, or 16. Make sure you change your strip config in WLED to match your GPIO choice. What ESP32 are you using? ---

The problem has been solved in the other thread: [24v strip: 12v works, changing adapter to 24v fails - Hardware - WLED](https://wled.discourse.group/t/24v-strip-12v-works-changing-adapter-to-24v-fails/7227/12) At the time I had the problem with two different 24v strips, but the solution ended up being the same.
