• WearableObservation (base profile),

• ActivityObservation,

• WearableVitalSigns,

• SleepObservation,

Value sets and code systems for:

Device types

• Measurement methods
• Activity metrics
• Vital signs
• Sleep metrics

Documentation pages:

• Home page with overview

• Profile documentation

The IG uses FHIR R4 (4.0.1) and includes proper terminology bindings to LOINC, SNOMED CT, and UCUM. You can build it using FHIR Shorthand (FSH) compiler (SUSHI).
