Attribute states not generated or not assigned correctly

[phantomski77]

Hi,

first of all - thank you for your great work making the Owlet finally available for Home Assistant. Much appreciated!

I own the Owlet Smart Sock 3.

Few issues regarding the alert states and/or attribute readings:

• LOW_INTEG_READ - when the sock is removed, owlet app produces the notification Difficulty getting reading, the base station starts playing music and flashing yellow. This attribute doesn't change state however. It only changes to true when the sock is put into base station for charging.
• base_station_on - when sock is charging, produces null, when the sock is on and active, produces 1 - shouldn't this be more base station connectivity, rather than sock connectivity (which is provided by active attribute)?

Thanks.
