Garage door with obstruction sensor and Homekit


So homekit supports an obstruction for a garage door. I can create my garage door in HA and Homekit and it work properly. I can’t however, find the setting to add an obstruction binary sensor to a cover in HA - am I missing something here ?

Thanks !

Did you ever get this working? I can expose the obstruction sensor to Home Kit, but it shows up as a completely separate sensor and not part of the garage door.
