ws2812b flickering every 1sec +- about artnetwifi HOT 3 OPEN

It is allways hard to tell from a distance.
But, how many LEDs are connected? 1 or 2 LEDs or maybe 100. More LEDs need a bigger power suppy.
Try the Standtest from Adafruit to check wireing and your power suppy.
Something wrong with your ArtNet transmitter?

I am currently having same issue. I've checked with multiple art-net transmitters. I've removed everything (including neopixels) except for simple short print to screen commands. About every 1 seconds, the art-net data streams stops. Like the esp32 is taking a quick little break.

Flickering LEDs is different from your problem. You don't get any data once every 1 second. Because of this I suspect a network problem. Bad WiFi? Bad ESP-Antenna?
Have you tried my ArtnetWifiDebug example? Is the frame-sequence in order or are there any missing frames?
