SW update needed: Stand reminder overrides Sleep Focus
Using the Activity App, I set a Stand hours goal and turned on the reminder to stand if I haven't done so within the last hour.
I also use the Sleep Focus every night to silence all notifications from Apps and block calls except from my Favorites or repeat callers.
I also wear my Watch while I sleep so that the Health data trackers (Heart rate, Respiration, Body temperature, O2 levels, Afib and Sleep Apnea trackers) can operate while I sleep.
About the time my Apple Series 9 watch updated to WatchOS 11, I started to get Stand reminders beginning between 3:00 and 4:00, during the time period I had set as Sleep Hours. The Sleep Focus turns on automatically at 22:00 every night and remains on until 6:00 the next day. I haven't noticed any other Stand reminders occurring between the hours of 22:00 and 3:00 when I'm sleeping soundly.
At first I thought this was a bug, but lately I concluded that the algorithm processing sensor data from the watch now determines that I am awake at this early hour, well before my morning alarm. As I'm still in bed and have been for several hours, the Stand reminder triggers when it should not do so. I thought it was the Stand reminder that was waking me, but now I realize I was awake--though half-asleep--and that inactivity is what the watch noted to send this unnecessary reminder.
The software should be updated so that the Stand reminder is suppressed if the Sleep Focus is still on. By way of comparison, if I rise before my morning alarm goes off, the Watch or my iPhone ask if I want to turn off Sleep Focus. It seems like a simple adjustment to state the conditions that: (1) if Sleep Focus is on (with or without the time of day being before an Alarm is set), then (2) the Stand reminder (or other Activity Reminders) is suppressed.
I can't always avoid waking up during the night and taking some time to fall asleep again. While it's great that the Watch algorithms are so finely attuned that they can distinguish wakefulness--no matter how limited--from sleep, they should not be prompting me to get up before I'm ready to exit Sleep Focus.
I could not find any other combination of settings in Activities or the Sleep Focus to disable or suppress these reminders while I'm asleep. The only work-around I can use at the moment is to silence notifications on my watch. I will still get the haptic tap on my wrist to stand up but usually that isn't enough to fully awaken me, and it doesn't disturb my partner like the notification sound does.
