Hue integration lights: controllable as a group, unreachable individually

Configuration
1

Hi,

I’m new to Home Assistant - actually switching from OpenHAB.
I’m perplexed by strange behavior of Philips Hue integration.
I have 7 OSRAM Hue lamps on my backyard - all connected through hue bridge. There are 4 floor lamps and 3 wall ones. The way it is setup in Hue Application is that I have “Backyard” room, and then 2 zones “Floor Lamps” and “Wall Lamps”.

After installing Hue Integration, it was imported in HA as (seen on the overview tab):

  1. Individual lights under the title “Backyard”. This one contains also a switch called “backyard” to cont roll all of the lights in this room.
  2. Something called “Lights”, which has only 2 elements/switches - “Floor Lamps” and “Wall Lamps”.

Now: I can control both wall as well as floor lamps through those two switches under “Lights”. But all individual lamps are inactive - sow switches are dimmed out.
Is that a normal behavior?
If so, then how to control then Individual lights?

Is this a result of “incompatibility” of HA and Hue (Hue has rooms and subordinate zones, which HA do not seem to have), then removing one level so making “Floor Lamps” and “Wall Lamps” rooms and not using hue zones concept will heal the situation?

Thanks in advance!
Help of any kind, or just pointing me into right direction would help a lot.

Best Regards,
