Exploring Heart Rate Monitoring with Watch 47c

I recently purchased the Watch 47c for my wife, and we’ve been exploring its features, particularly the heart rate monitoring. Last night, I noticed that while it recorded her sleep data, there were no heart rate measurements logged. This got me curious—what triggers heart rate measurements by default? Is there a way to set it to record more frequently, say every 5 or 15 minutes, during sleep or throughout the day? My wife is interested in gathering more health data, and I didn’t see any obvious settings for this in the app. Battery usage isn’t a concern for us, so we’re open to any suggestions that might help us achieve this. If anyone has experience with similar devices or knows of a workaround, I’d love to hear about it! :blush:
