Hi!
I’m a little bit surprised that the standard Zigbee effects (like colorloop) are gone. As I use a Deconz hub, I don’t have the possibility to use other effects 
Is it planned to bring these effects back?
They are still available but were moved to another place. In Hue Essentials, open a room, tap your light (to open colour picker), and then go to the effects tab. Can you see the effects there?
Perfect, thanks for helping!
