@joern it seems that there is a way to get it unpaired from the app.
and then fetch the data to the mirror.
now for the sleep status , maybe you could get the heart and do a program calculation of the pulses(update actually the movement is calculated from 12 until 6am, so you have to program gyroscope or something like that) when you were most rested and get the sleep status… deep sleep, weak sleep, etc.
And even get a message like, you slept well, or you slept bad.
what do you think?
