LIFX Z - more than 20 zones?

Hi,

Trying to set up my new LIFX Z with 5 sections (should be something like 40 zones).
My problem is that it doesn’t react for any zones above 20. :frowning:
Is this “working as designed”, or is me who are doing something wrong? I really would like to be able to control the remaining zones.

I’m runnning OH version 2.5.9.

Cheers,
Anders
