In the past, it was possible to share a HomeKit “Home” on iOS to anyone else.
Since Apple’s 2023 changes to HomeKit, only users with a Home Hub (currently a compatible iPad at home, or Apple TV) can do this.
For everyone else, a workaround would be to pair an Apple device using the HomeKit bridge QR code, but HomeKit bridge only shows the code once at initial setup.
Couple we please have a service to manually invoke the pairing QR code?
