The Open Home
Foundation, which governs the Home Assistant
home-automation project, has announced
the "public preview" of its Device
Database:

Providing a public, open way to browse the anonymous, aggregated
device data we collect was always part of the plan, and this preview
is our first step toward it.

You can already use it to search and filter devices to see
aggregated community insights, starting with a deliberately focused
set of specifics, such as whether a device requires an internet
connection, and which protocols and integrations it works with. We've
kept that initial scope narrow on purpose, giving us a solid
foundation we can build on together with you, our community, as the
database grows.

LWN looked at Home
Assistant in May 2025.
