Zigbee2mqtt grouping

Was at the summer cottage this weekend. Switched from ZHA to z2m.

I have a lamp in the roof with five ikea LED1949C5 bulbs. Pairing was no problem, just like charm.
But when I grouped them together, it does not show the color temperature for the group, only brightness.
Individually, for each bulb I can change it, but not for the group, ideas anyone?

Got it working, but this was an odd oneā€¦
It only shows color when it is one, in one way that makes sense.
After fiddling with them in a Panel Cart, they show up in automations :smiley:

So, adding a group to some random panel, play around with them and they are exposed to HA :smiley:

A good start of a monday!
