Pardon a WLED question in the Home Assistant community, but I was unable to find a WLED community in the fediverse.

Regardless, I have this 720 LED/meter FCOB strip, which is 24v strip & I'm trying to figure out what to configure the "LED voltage (Max. current for a single LED):"

Since it's a 20IC per meter & they claim 21watts per meter that comes out to ~1w per IC. But I'm unsure how that converts to mA like WLED is asking for.

Any advice would be greatly appreciated ๐Ÿค

If i'm understanding your question, what you're looking for is Ohm's law
Amp = watt / volt
1 / 24 = 0.042
You want milliamps, so multiply by 1000 giving you 42mA per IC

Thank you!

I guess the second part of my question is I want to confirm that WLED says "per LED" they really mean "per IC".

Yes that's correct. Same goes for the normal WS2811 strip lights which are addressable every 3 LEDs.

Yes, they understand an led as a thing they can control. I have an analog strip that is one LED

I'm happy to help.

I don't know much about WLED, but from the other comments here it would appear so. And i think it's also what makes the most sense.
