Thank you. The system doesn't generate the .sleepAnalysis samples in that duration. There was no sleep data saved in the Health.app for the test. I tried changing the Sleep bed time to be before the testing window, but still no data was saved in the 30 minute extended session window. Is there a way to programmatically force sleepAnalysis to be collected in a 30 minute window?

Thanks for confirming that. sleep analysis work for my use case then. I’ll use heart rate and accelerometer only.

^won‘t work
