I assume you mean the “old” vs. the “new” Home architecture? Yes, it works with the new one. I’ve switched ages ago and the bridged devices are still working as expected.
With iOS 16.4, iPadOS 16.4, tvOS 16.4 and macOS Ventura 13.3 released on March 27, 2023, Home received the option to upgrade to a new architecture which was rebuilt from the ground up to be more efficient for users with multiple Apple Home devices.[21][22][a] Once a home is upgraded to the new architecture, devices using older operating systems can no longer access the Home app.
According to this, I am still using the “legacy architecture”… and my Apple devices warn me that it will stop working in 2026 and I should upgrade Apple Home…
Will the HA Homekit Bridghe continue to work after I perform this upgrade?
