Colmi R02 / R06
Budget ring that is "highly supported" by Gadgetbridge, so you can sync it fully locally with no vendor account. No official API.

Oura Ring 5
Same data story as the Ring 4: official REST API (v2) via your own OAuth app, but Gen3-and-later rings can't use the API without an active Oura Membership ($5.99/mo or $69.99/yr in the US). Data download through the Membership Hub works without one. Home Assistant support is community (HACS) only.
