Great project! Until now I do not have anything connected to my bed, I can't sleep with something attached to my wrist, so no sleep data. Tracking the sleep would be really great, but the current solutions seem not right to me.

I would welcome a system, which may be used as a pod sensor, like the mentioned EightSleep or Withings, both not visible. But I want to set when something is radioing around my bed. Just like on my smartphone, where the flight mode is activated, I would like to set the device so that the data is only synchronized via WLAN or Bluetooth when I am no longer lying in bed.
