Crazy Altitude

[zhang965]

Hello,

I noticed the altitude in the sleep log is changed .

Normally it’s about 62m for awhile, and one day it becomes negative, (-12) then keeping it until now

I sleep in the same place…

And my watch altitude shows the negative value as well

If you notice the same behavior, please report.
Thanks

Nope, I don’t think so, I sleep in the same place.

with that info added it is indeed different to the other topic.
I think it’s more the question why the altitude was so low and did you notice before and after?
something must have been different that day

@zhang965 right. In my case it’s just the watch that showed incorrectly but the app showed correctly. And it’s apparently been solved in the next build.

happened to my watch many times. it will become negative. i think because of the weather changes it will affect the altitude. Usually after turn on my GPS for outdoor exercise it will fix this issue. Or you can adjust it at the Outdoor setting there to correct it.

Jaja, today is a sunny day and I wake up with -30m altitude.

Damn, I thought someone buried me last night, -30m! It’s a lot of work.

just to be sure. this is the altitude you also see when you flip to the altitude widget?
it is not only shown in the oxygen widget?

My bad I shouldn’t listen it…

@zhang965
see, you have been warned
looks like altitude is shifting excessively on your watch. you’re experienced and I assume you’ve already checked if the sensor is free and clean?

I see it that dramatic only for a while when the sensor is soaked in water, eg. when taking a shower. Never had a subterranean barometric reading (but GPS is a whole other story! )

After listening to stairway to heaven, It shows 86m now,

@zhang965 I am close to sea level but on the 5th floor of a building and my S9P (not PP) shows -1m. Has been pulling those stunts all along (and I think my S9B as well, but would have to check). Might be that whenever you are “broadly“ stationary but not from the watch‘s perspective (b/c you eg took a shower, walked the stairs etc), subsequent changes in pressure then get interpreted as changes in altitude w/o any GPS correction as long as you do not start an exercise…

Ja, I know, but I’m concerning during first 2weeks it shows 60m, and then it turned to -12m
