Oura Ring 4
Official REST API (v2) via your own OAuth app (personal tokens were deprecated in Dec 2025). The API needs an active Oura Membership; data download via the Membership Hub doesn't. Home Assistant support is a community (HACS) integration.

Pebble Index 01
A $75–99 voice-note ring (button + mic) from Core Devices, the revived Pebble. It is NOT a health tracker: no heart rate, sleep or step sensors. Recordings go over Bluetooth to the open-source Pebble app, which can transcribe them on the phone with no internet. A per-gesture webhook POSTs the raw audio (16 kHz M4A) and/or transcript to your own server, with optional HMAC signing. There's no Home Assistant integration, though the webhook or button gestures can drive HA automations yourself. Gadgetbridge supports classic Pebble watches, not this ring. Signing in with a Google, Apple or GitHub account is required. Shipping since July 2026.
