It's possibly some coding trickery based on the channel priority. GH>EF>CD>AB. Maybe GH channel light function is set to Parkenlicht as normal then EF is set to something else with the dimmer value set to 0. AFAIK the BCM will smoothen it's outputs BETWEEN different dimmer values within the same channel. but it can't for example fade in or out of a light function.

Would also love to know how this was done.

EDIT: Just a thought... Potentially GH is set to Parkinglicht then EF is set to ComingHome/LeavingHome function with dimmwert value of 0. Though this would mean losing the CH/LH functionality and sidelights probably would need to stay on at all times. Just thinking out loud!

Unless the later versions of the BCM actually supported fade in-out natively.
