I finally understand the dip switch and now it is all showing....
By the way, if I am using #1 floe riing for 1st Hub, and set the RGB to temp.
It seems I couldn't use #1 for Riing Plus for 2nd Hub, RGB setting will conflict with my floe riing
Currently, I am avoiding #1 on my 2nd Hub and all things work well.
