Control two Hue-bulbs simultaneously

Hi,

I try to control 2 Hue-bulbs with one Colorpicker simultaneously.

This are my definition in the items file:
Color Deckenlampe1_Color “Deckenlampe1” (gHUE) {channel=“hue:0210:00178841f464:1:color”}
Color Deckenlampe2_Color “Deckenlampe2” (gHUE) {channel=“hue:0210:00178841f464:3:color”}
Group Deckenlampe_Color “Deckenlampe” (gHUE)

Now I created a colorpicker in my sitemap:
Colorpicker item=Deckenlampe_Color label="Deckenlampe" icon="overhead"

But if I change the color at the colorpicker, the bulbs don´t change their color.

What did I do wrong ?

Regards
Philipp

Why 2 Items ?

Item

Color Deckenlampen_Color "Deckenlampen" {channel="hue:0210:00178841f464:1:color", channel="hue:0210:00178841f464:3:color"}

Sitemap

Colorpicker item=Deckenlampen_Color label="Deckenlampe" icon="overhead"

What Bulbs ? Ikea Tradfri RGB Bulb?

Sounds Good. What happens if both light have different color, what color will the item have?

The question is in what situation this could/should happen? Using such a setup you should desire to have them in the same state all the time ( except when connecting the bulbs the first time, a simple command given by the sitemap should solve that).

Kevin’s suggestion is the best one. But to answer the original question, the problem is you have to add the Color Items to the Group.

Color Deckenlampe1_Color “Deckenlampe1” (gHUE,Deckenlampe_Color) {channel=“hue:0210:00178841f464:1:color”}
