Y = confirmed for this device type, Partial = works with limits, N = not supported by this platform, Unknown = not enough dated evidence. These are type-level answers, not a guarantee for one product.

What this means

Support for automation triggers works with limits — check the product notes before you buy, because individual products may implement less than the device type.

Requirements

Hub requirement: Google/Nest Matter hub required. Thread border router for Thread devices.

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.
