Quick context - I have white LED strips under my kitchen cabinets that need to be replaced. So I bought some RGB, and a controller that has RGB as well as W and WW. But, I figured that even with RGB, you can set the colors to match a color temp, and in fact if you want 2700, it's 255, 139,39. But, it's nowhere near as bright as the white ones were, though when I set to other colors, it's fine.
So, rather than rip the new stuff back down and start all over again, I figured I can go ahead and buy some more white LED strips, and just put them next to the RGB stuff under the cabinets since there's plenty of room, and then connect them to the + and either W or WW on the controller.
But that leads to my questions. Would I used W or WW? I'm assuming that's White and Warm White but correct me on that if I'm wrong. And in Hubitat, how do I tell it to turn on either W or WW instead of the RGB? In the device settings, I can set a specific color temp (and no, that doesn't set the RGB strips, it turns them off). But I don't know how to select what connector I'm using on the controller, unless I totally missed a setting somewhere.
I am pretty sure the W or WW is a property of the LED strip (well it was for me anyway when I was sourcing strips) I went for super bright W and just tuned them down to WW using yellow. So you would just use the white value driver 0-255 for the control of that LED strip.
TBH ive used HA to control my RGBW light strips as I needed some complex YAML stuff that would have been a bit more complex to do in rule machine.
RGBWW means the controller is expecting 5 led's it is expecting red,green,blue,cool white, warm white. Generally this type of controller will turn off the RGB led's when trying to use a color temp value. A color temp value will then use both of the white LED's mixed to try to generate the CT you want.
Technically you could atttach seperate strips with a low and high CT value, but who knows how well the controller will actually achieve the CT you want.
You would be better off getting a strip that is RGBWW.
The controller has a chart on the side showing what wires to connect to for RGB, RGBW and RGBWW (I may have that wrong off the top of my head as far as the labels), so I'd think that one white set of LEDs would work, but I could be wrong.
This really depends on how the controller thinks it should work. Generally speaking when you have cool and warm white led's on your strip they will be used when setting a Color temp. Because those led's are generally larger and brighter when included.
