I am looking for the best way to automatically get Apple watch health data into HA. I found a few topics on here, but all quite old, so things may have changed or improved.
Purpose:
I would like to map sleep patterns, heart rate, breathing rate and oxygen% against the CO2 levels I am already monitoring in HA.
By using a combined CO2 monitor I have evidence that we are getting high levels (> 1,500 ppm) overnight in our bedroom, even with the door open to the rest of the house.
I wake in the night sometimes - does this correlate to high CO2 moments?
I sometimes wake feeling like I have slept poorly - is this related to high CO2?
With the data overlaid, I can try to evidence the problem and then look to address it (not just opening a window). With a modern insulated house, the solution may be some sort of heat recovery system that introduces fresh air.
