Homekit Bridge from other network

The problem

Hi I have been using homekit integration for several years and I had no problems until the arrival of the new homekit architecture, because it required the use of a hub to work remotely, since I have 5 different homes, via the wifi of my main home , that is, where I installed the home assistant server everything works correctly, only my main home worked remotely because the Apple TV was present there.
In other homes I get the warning that a hub is required for remote operation.
the other day I bought another Apple TV and installed it in my second home, the warning that a hub is required is no longer there but when I try to connect remotely the devices are not available, subsequently without changing home , I try to connect the new Apple TV in the main house and the second house also works correctly remotely.
However, my intention was to also equip my other homes with Apple TVs as it makes no sense to have 5 Apple TVs in a single home.
Is there a way to trick Homekit into believing that the Apple TV is actually in your first home?
I have my homes connected via VPN but it doesn’t work, I also tried tailscale installed on Apple TV but it doesn’t work either.
