About Home Interop
Home Interop answers one question per page about connecting smart-home devices across ecosystems — Matter, Thread, Apple Home, Alexa, Google Home, SmartThings and Home Assistant. Each answer names what works, what stops working, and the document it was checked against, with the date of that check.
What is here
One question per page. The answer is the opening paragraph, written so it makes sense on its own. Detail follows underneath, and the documents the answer was checked against are listed at the bottom with the date each was read.
Why dates matter here
Platform behaviour changes without notice. A bridge that exposed a battery level last year may not expose it now, and vendor documentation often lags the firmware. Pages that describe changeable behaviour carry a visible last checked line so a reader can judge how stale the claim is, rather than guessing.
Where the answers come from
Published platform documentation, specifications, and release notes — attributed and dated. Where the platforms' own documents disagree with each other, the page says so and attributes both sides instead of picking a winner.
Corrections
An answer that cannot be trusted is worse than no answer. Pages carry a published date and, once revised, an updated date.
