Globes can ONLY be assigned to one controller at a time, now obviously the Hue Hub is a controller, as well as Homey, but so is the living colors remote. So no you cant use both at the moment.
Now it’s funny you should mention this, because I actually have 5 of these remotes floating around, and they are damn good remotes.
I was considering looking into adding them as independent zigbee devices into Homey, but I would imagine it would be a large under taking, that may never work as they use LighLink protocol.
Your best bet is to actually contact the developer of the Hue Zigbee app and ask whether they would consider adding it. Once you can add it to Homey as a device, you could use the remote to control what ever you would like …
