What this means
All four answers are confirmed for this device type on this platform. Individual products can still implement less than the device type — check the product notes before you buy.
Requirements
Hub requirement: Apple Home hub (HomePod / Apple TV) recommended; needed for remote access and automations. With iOS 18 or later an iPhone can add and control Matter accessories without a hub (iPhone 15 Pro or later for Thread accessories); otherwise Thread accessories need a Thread-enabled home hub or border router (Apple 102135, May 2026).
Software: Apple Home iOS/iPadOS 18.4 (per Matter Alpha + reviews; not in Apple release notes) or later.
Matter spec: 1.2+.
Confidence
The evidence is a mix of official platform documentation and product- or community-level reports; some answers rest on documentation alone.
