ArtNet VS WLED

This library specifically supports ethernet https://github.com/hideakitai/ArtNet

Did you try this one? https://github.com/hideakitai/ArtNet/blob/master/examples/Ethernet/receive_fastled/receive_fastled.ino

Then if you can use artnet you should check this library : https://github.com/hideakitai/ArtNet It has a function for directly send data to leds.

I think you're one of todays lucky 10000 [0] learning about WLED [1] today :)

I’ll do you one better: Here is the WLED main site - they cover everything - however you want it for your vehicle is up to you! (If you want to see a truck I personally worked (with 2 other main guys doing the woodwork and wiring) on that was probably the “most expensive” project with these controllers, check out the SEMA entered “Realtree Stormtrooper truck” - a LOT of time went in to that and almost a year of prep, not a fan myself, but custom electronics are what I like doing)

Did you use the esp32.bin? If so, you should instead use ESP32-C3 here: https://github.com/Aircoookie/WLED/releases/download/v0.14.0/WLED_0.14.0_ESP32-C3.bin

Friend replaced all his govee cintrollers with WLED.

I feel like I should start this post with a disclaimer. I tend to over-complicate things. Which means I'm making this post partly as a sanity check and partly to fill in some gaps in my kno.wled.ge

Look at WLED.
