“There are two use cases we’re targeting:
Use case 1 — Filling gaps in HomeKit device support: Apple has started using Matter for new device types rather than adding them to HomeKit directly. Vacuums are a recent example — Apple added vacuum support to the Home app, but via Matter, not HomeKit. Our goal is to bridge that gap so Homebridge plugins can deliver full functionality for these device types. We think this is very achievable and the more immediate target.
Use case 2 — Using other Matter controllers with Homebridge plugins: This would allow your Homebridge plugins to be accessible from other Matter controllers, like the Aqara app for example. This one is more of a longer-term effort — it will require individual plugin updates to support, so expect this to roll out gradually over time.
Our goal remains a single platform that supports both HomeKit and Matter, backed by our existing ecosystem of 4000+ plugins.”
