Below is finally a video link to my pool light install using the Fibaro RGBW Controller. The lights along the top of the pool are two RGBW strips wired together while the waterfall lights are two 24" rgb lights.
When the waterfalls are off, I typically use the controller slider to remove the “color” from the LEDs. This basically turns off the waterfall lights and just leaves the white lights on behind the pool. That way they match the landscape lighting. I have them come on at sunset and go off at midnight, The landscape lights are controlled by my pool automation controller, so they are separate from the Fibaro system. All in all, I think it works pretty well. Now I just need to convert the pool light from halogen to RGB or RGBW LED to get the colors to all sync up.
