Yes, very easy to program. I haven't used any of the presets, preferring a simple ramp up and ramp down at either side of the photo period.
You basically set the brightness of all channels (WRGB) that you want to achieve at a given time, and the levels will ramp up or down to that level by that time.
I find the July firmware release a clearer, so probably worth doing the automatic upgrade. Juwel has some YouTube instructions if you want to see for yourself.
