Seems something works not properly / stable ? Maybe FitBit team could comment.
one night all worked well I got Spo2 93% at the screen, but last night it said “could not read” although spo2 graph appeared properly
Any advise ?
thanks
Best AnswerThe first pic is EOV chart which is Estimated Oxygen Variation and differs from SpO2 metric shown on your watch. There are several reasons while spo2 could have encountered issues, for example restless sleep, watch worn too right or too loose, different forearm location (more fat tissue), etc. Do not worry. It can happen. It happens with all my devices Garmin and Fitbit included.
