Spo2 reading in day summary

[herlas]

I have Spo2 readings turn on during sleep but I’ve removed the widget that allows on demand Spo2 readings, in my day summary screen some days have the graph for Spo2 and others don’t. Either shouldn’t be there at all or be there everyday?

@herlas
could it be that it is altitude related? (location, where you are active and then sleep)

[herlas]

@freeheeler no changes in location/altitude either

@herlas this is known. What happens sometimes is that the last reading during sleep happens at a time when your watch later decides that you were not sleeping, and so the reading is categorized as a measurement outside of sleep. If you notice they are always close to when you wake up, or when you put your watch on after it was off your wrist.

@isazi Thx, at least it’s known. In my case I always have my watch on. Sometimes this Spo2 chart appears to be aligned to the end of a gap in HR sometimes isn’t.
