I don't think it will do that. I think it tracks when you've spent a significant time asleep. I have the amazfit bip and mi Band 2, and I only have it work when I'm not moving and sleeping at night. I don't think it works for stuff like naps. The best you could get is 24 hour monitoring...|
... You COULD try with sleep as android integration using a 3rd party app like Mi Band Tools or Notify and Fitness for Mi Band.
