No Sensor Data
Before We Start
If you genuinely have not been wearing your Watch and you are getting the not been wearing your Watch banner over the clock, then check back in about 45 minutes after you've put your Watch on.
Identifying & Solving Problems
Occasionally you will find that either AutoSleep has no access to your Watch sensor data, or, your Watch is not capturing any data.
The Watch is supposed to do this automatically regardless of whether or not the app is installed.
How to Prove This
This is very easy to prove.
All heart rate readings for the day are listed here.
Scroll to see the times that you wore your watch whilst sleeping.
If the watch is functioning correctly, you will see heart rate readings every 2-10 minutes.
The most common problem is permissions, but this is closely followed by people that either don’t use a password or have wrist detection turned off. Both of these disable the Watch’s background health sensors.
What to do?
The first thing to try is this:
Important: make sure that you do every step in this order. Often the problem is due to OS services crashing and this restores them as well as the app’s permissions.
This can sometimes completely fix the problem.
If the above doesn’t solve it, then here are the likely causes for the Watch to cease capturing background heart rate.
If you have re-installed the app and checked everything in the check list and you are still not able to see heart rate data in the Apple Health app for the times that you are wearing the Watch whilst sleeping, the next troubleshooting step is to re-pair your Watch and iPhone.
IMPORTANT: We've found that most people have success when setting up as a new Watch instead of taking the restore from backup option, which tends to carry across old problems.
