Philips hue discover

am using the hue zigbee app and am very happy with it. (over 20 devices connected)
Now I bought a Hue Discover (outside lamp, same as Welcome, but color).
This is not yet in the library, and when trying to install as Welcome, it does not want to do that.
It has installed as Unknown Zigbee Device.
I can switch on and off, but no color, no brightness. (and no cute logo).
Anybody can help?

You should ask the develpor of the app, to add the specific lamp into the app. otherwise its not gonna work.
