Data on Sense 2 not making sense

[TJGG]

I just started using a new Sense 2, coming off a Charge device. I've had several fitbits and the data always made sense. Since I've had the Sense 2, my sleep data is off. It keeps telling me I've only had an hour or two of sleep when I've slept all night long. It tells me I've had no deep sleep when I wake up feeling great. My workouts are also way off. I've been wearing Fitbit for a long time so I know what I normally see. With this one, it keeps telling me that I've either had no minutes in the active zone or not very many. For one recent hard workout, it told me ALL  minutes were below zone. It also stops working in the middle of a workout. The readiness score seems backwards. I get a high score telling me I'm ready to do a hard workout, on a day I feel awful. On a day I feel fantastic and ready to knock it out at the gym it says I have a very low score and shouldn't work out. With my prior devices I've always had a resting heart rate right around 62. This one says my resting heart rate is near 80 consistently. There's just no way all these things are that different than my other devices and it doesn't make sense. Wondering if I should return this, if there are flaws in this one?

Hi @TJGG - while heart rate on the Sense and Versa watches released after the Versa 2 can be inaccurate during movement and exercises, some over read and others under read, they are normally good at rest which doesn't seem good in your case. The high RHR could be why it's not recognising sleep properly and it may be faulty.

If you have tried restarting the watch and it hasn't improved and you are unhappy with the watch Fitbit have a 45 day refund policy or possibly authorised dealers too, some stores provide 14 to 30 day refunds.
