There are two main Zigbee integrations - Zigbee Home Automation (ZHA) and Zigbee2MQTT (Z2M).
There is no list for ZHA because it aims to support all compliant devices out of the box - a list would be impossible to compile.
“Compliant” means:
- No bugs
- No extra features not in the specification (manufacturers are allowed to add these)
Instead you have to look for a list of devices known not to be supported by ZHA. There’s one here:
As issues are resolved by the addition of custom device handlers (quirks), these devices will gradually get included in the ZHA integration, but a great many devices just work, particularly the simpler ones.
With Z2M it’s the other way round. Every device has a custom device handler, compliant or not - so it is possible to list supported devices. There’s also a lot more people working on device handlers, so new devices get supported more quickly - Z2M is not part of Home Assistant and has its own thriving community.
There is a database of devices supported by ZHA and Z2M, but this is based on user contributions, so more research is always needed:
There is a Zigbee buyer’s guide thread in Community Guides. Search the forum for comments on specific devices.
