Stairs not counting

[Xraydoug]

I just climbed 4 flights of stairs - 10 each - but my Fitbit One did not record any flights. It has been doing this for several weeks. Cause and cure?

For the last several weeks my One has not been counting stairs that I've climbed. For example, I just climbed four flights of ten stairs each, but the One recorded nine of them. Cause and cure?

Hi @Xraydoug welcome to the Community!  If your tracker measures floors, it detects floors using an altimeter, which is a sensor that calculates altitude based on atmospheric pressure. Though your tracker is designed to look for pressure changes based on elevation gains, pressure changes due to other causes—such as a gust of wind, a weather change, or opening a door—can occasionally cause your tracker to register some extra floors. Another factor is floor height. Your tracks registers one floor when you've gone up about ten feet, which is the average between residential and commercial floor heights. If you climb long staircases you may find that the tracker’s floor count doesn't match how many floors you've gone up since the staircase was taller than ten feet. However if none of the mentioned factors are occurring, then could be a glitch on the software that is causing it to count more stairs. So let's go ahead and perform a restart by following the instructions on this post. 

Let me know how it goes.
