Fitbit Sense Temperature Not Working

[Renaye]

I’ve worn my sense for 4 nights now and my temperature baseline says 0 degrees. My graph says my temperature has reached -3.5 degrees. Is anyone else having problems with the temperature sensor being very inaccurate?

I think you are misinterpreting the info.  It is not showing any actual temperatures, only temp variation from your baseline.  The vertical degrees axis is not actual temperature, but temp difference from your baseline.  Your temp baseline is set at 0 degrees.  If you see a night's reading of -3.5 degrees, that means your skin temperature that night was 3.5 degrees lower than your baseline.

Yes I definitely was misinterpreting the info! Thanks for the clarification!

I get how the temperature variability works, but on the next graph, "core temperature", shouldnt it show the actual temperature?

Yes, if you have entered it.  The only way Fitbit would get your Core Temperature is if you measure it yourself and manually enter it.

That's a good explanation but I notice that my Oxygen Saturation is now 96% and my sleep breathing rate is 12/minute - I doubt these are all variation measurements too. 

It's like Boudreaux saying, "Don't worry about the wind speed, it's only 8 mph."

And then Thibodeaux says, "But it was 149 mph five minutes ago, so we're at CAT 5 now!"

No, you were not misinterpreting the information, it's simply presented incorrectly.

Instead of saying "Last night: -1.7F" it should say "Last night: down -1.7F" so that you read it as a change, not a measurement.
