openHAB2 with Philips Hue

Hello,

i’ve set up openHAB2 on a Raspberry Pi 3b.

Currently i run all philips hue bulbs particular (to example one hue lamp with 3 LEDs (bulbs).

So it works to switch a single bulb on/off etc, but i want to have a group of this 3 LEDs (Bulbs) to change the hole lamp…

How can i setup this?

What is the difference between Philips Binding and Emulation? Can i run both together?

Thank you very much in advance
