Found a much better way for my S6 to use real room cleaning instead of zon cleaning.
No need for cordinates:) The number in params match a room in the app.
In my case
19 = Hallway
18 = Living room
17 = Bedroom
16 = Kitchen
vacuum.send_command
command: app_segment_clean
entity_id: vacuum.xiaomi_vacuum_cleaner
params:
- 18
