Hi community, I was hacking one of Govee outdoor LED lights, and, because it’s WS2811, it works with WLED. But it has 15 bulbs and 30 LEDs, and every second LED is (warm-)white, but addressable, and every other LED is a normal RGB one. Does WLED support such setup? I mean using nearby LED for brightness/white balance. For now, I’ve remapped all LEDs into two segments: RGB and White, but it’s quite sub-optimal. Thanks, ---

Yes, it uses 3 wire protocol. See the screenshot for the config I now use. ![Screenshot from 2023-10-03 09-38-34](https://global.discourse-cdn.com/free1/uploads/wled/original/2X/7/7c48723827f4ec2b346e90cfa76905d5e3594a8d.png) Then, to make working, I either remap LED via ```auto { "map":[0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,1,3,5,7,9,11,13,15,17,19,21,23,25,27,29] } ``` and then make two segments, 15 LEDs each or it’s also possible to do that without remapping, by using overlapping segments and spacing ---

Hey, that’s quite interesting! I’ve never seen a dual chipset setup in a single housing for addressable LEDs before. Does the ws2811 not typically have **three channels** for **RGB**? > I suggest for now mapping might be your best solution right now, even though it’s not the ideal method. > Another option could be trying to cut off the addressable white section if it’s not needed. > Unless you want to keep white 😀 The use of the Ws2811 chipset for white is somewhat unusual, so there may not be other solutions available yet. You might want to consider asking the developers about this and maybe providing an update on the situation. This will hopefully bring you further! Regards, `Gabriel` ---

From that photo, I can see 2xWS2811 drivers, but **4** LED elements, 2 RGB (centre “white”) and 2 WW (centre “yellow”). Each WS2811 can drive 3 channels, typically R, G, B but it’s possible to attach any colour LED to any channel (even WW). The chip has no idea what’s attached, it just outputs the current request you send via the data stream for each channel. Probably the pairs of RGB and WW LEDs are put in series so they can run at higher voltage (helps eliminate voltage drops). The RGB LEDs are driven by 1 chip using RGB channels and the WW are driven by a single channel (one of the RGB) on the 2nd chip. You can test by varying the Red only on one of the “white” LEDs in your segment (the odd ones?) and then try varying Green only and Blue only. You should see one of the RGB channels controls the brightness of the WW and the others do nothing. One last possibility: there’s more circuitry on the back side of the board, we can’t see. ---

> You can test by varying the Red only on one of the “white” LEDs in your segment (the odd ones?) and then try varying Green only and Blue only No, it doesn’t work that way. Any single channel color (R, G, B) gives the same brightness on the “white” segment, any pair (C, M, Y) gives slightly brighter light, and white is the brightest. Last weekend I’ve migrated one more Govee outdoor LED string to WLED, of different model, and its setup is even more challenging: it again has two chips/LEDs per unit, but White LED’s brightness is inverted: it’s OFF when brightness is 100% and OFF when 0%. Govee probably simply optimizes their designs, using same WS2811 chips, controllers, wires for many products, even by using additional WS2811 chips to white-only LEDs. I can live with two segments, one for RGB another for White, the real limitation is that I can’t get the full brightness/contrast when White segment is OFF, and it’s quite tricky to use any effect utilizing both segments. Solid colors are easier, as I can tune both segments to get the desired color/brightness. So it would be great to somehow compensate brightness of each RGB LED with the neighbor white LED in more automated way. ---

WLED may not support it yet, but NeoPixelBus the underlying library it uses does. Look for a color order like Rgbwxx. ---

Hi, I tried setting up the Govee H7050 and ran into the same issue. The color segment works great, but the white segment can only be turned off by setting it to red. And the brightness slider is reversed too. Any way to get this working? If not, should I file a feature request somewhere? Could it be implemented as a usermod even? I’m willing to try coding it if anyone has pointers for how I might approach it. Thanks! ---

Just converted my Govee H7021 12v big bulbs to wled just fine but i have question. These are ws2811 just like in photo above. 2x rgb and 2x white led. What setting for mA/Led is safe? I have tried 30 mA and 35 mA just fine but on smart energy meter i see that original govee setup with 2x (15+15m) total 60m was drawing cca. 32 watts, now with wled controler and similar efects (combining also white leds) it draws max 22 wats. My new power supply says 12v 3a = 36w. So… is it safe to set higher mA? Will it make difference? Or is my new power supply actualy fake and capable only 2A or 24w? 😉 ---

You should not run a power supply at max rated load and many will not last long doing so. Generally you should not use more than 80% of a power supplies max rating. ---

My dillema is why i get readings: - with official govee power suplies on my smart meter plug around 32w, - with separate no name 36w power supply and wled controler only max 22w. Are govee strings in original settings getting more mA per led? But at the end it may be just fake specs on no name power supply saying 3a but is actualy 2a 😉 ---

Try turning off the brightness limiter and see what it says. You are setting values in WLED that is just a software calculation to dim the LEDs to use less power. WLED does not physically measure anything. It is sort of an educated guess as a limited safety feature. ---

Also different power supplies may be more efficient than others when converting AC to DC. Hard to test something like this using a smart plug. You would be better off measuring the current draw on the dc output to the LEDs. ---

For anyone interested (@kvj @roggz) I’m preparing official WLED support for dual chip RGBW LEDs as pictured above. I would appreciate any beta tester. [Next page](https://wled.discourse.group/t/ws2811-led-strip-every-second-led-is-white-only/9355.md?page=2)
