@erfind I know this is old (and possibly not the right forum), but I'm working on updates to the documentation to clarify this:

# Example filter to include specified domains and exclude specified entities
homekit:
  filter:
    include_domains:
      - alarm_control_panel
      - light
    exclude_entities:
      - light.kitchen_light

Filters are applied as follows:

• No includes or excludes - pass all entities
• Includes, no excludes - only include specified entities
• Excludes, no includes - only exclude specified entities
• Both includes and excludes:
  • Include domain specified
    • if domain is included, and entity not excluded, pass
    • if domain is not included, and entity not included, fail
  • Exclude domain specified
    • if domain is excluded, and entity not included, fail
    • if domain is not excluded, and entity not excluded, pass
    • if both include and exclude domains specified, the exclude domains are ignored
  • Neither include or exclude domain specified
    • if entity is included, pass (as minor typo in docs #2 above)
    • if entity include and exclude, the entity exclude is ignored
