@chemelli74 I am developing a new version of the component with completely redesigned code.

superseded by #751

@bdraco Your version of zeroconf no longer generates ServiceStateChange.Removed events. I checked history.
v0.31.0 was latest version with support this event :(

@AlexxIT Its definitely still supported and just verified we are firing them with a homekit device.
