Yes, Oura Ring 4 is fully supported. It uses the same Oura Cloud API as every other ring, so there is no device-specific limitation.

Oura via Terra delivers four payload types:

• Sleep: stages, HR, HRV, respiratory rate, scores (plus SpO2 if the scope is granted)

• Daily: readiness, activity summary, resting HR, HRV, stress

• Activity: tracked workouts

• Body: VO2 max, personal info

Data is polled automatically, and you can run a historical data pull to backfill a given date range.
