Hello… I have a weird issue with my led controller. I have WLED v0.14.4 “Hoshi” running on an WROOM ESP 32 which I have had running for months with no issue. I have a preset of one color (red) for a night light. I have WLED integration installed in Home Assistant (current core, etc). The LED comes on at the scheduled time and the preset is active and I see the one red light. But what happens sometimes is that a while after the LED is turned on w/ the Preset, it starts with random rainbow colors flashing. When I look at the WLED Web GUI and click “Peek”, I only see the Red color, not what the strip is actually displaying. If I click the “Power” button in the GUI the LED strip only partially turns off. That is, it’s not flashing rainbow colors anymore from end to end, but has a section mid stream on the strip that is lit with muted rainbow colors  
not blinking. The “Peek” no longer shows the Red color but is blank.

First thing I would do is add a proper [level shifter](https://kno.wled.ge/basics/compatible-hardware/#levelshifters)

Thanks @Jinx, I wasn’t aware of the 3.3v issue with the data signal. I’ll give this a try.
