@cwitter I’m not sure if you use node-red, but if so I made a subflow that automates the color setting of the LZW45 within HA. It works just fine for all 3 of my strips, but may not be as intuitive as you’re hoping it to be.
I can confirm if using the color wheel in HA it doesn’t consistently work for me either. My strips have the same problems you describe, blinking/not setting correctly. But if you use my subflow and define the color/effect (if wanted, use solid if you just want a solid color), this will set the colors just fine for as long as you want.
I have the subflow posted here on this thread: Node Red - Automate LZW45 Quick Strip Calculations (Parameter 21) via Subflow - #11 by harmfulmushroom
