How to turn off the HR sensor?

[Love_and_Decaf]

I can tell my watchface not to read the HR sensor, but the background health app still keeps it running (light keeps flashing). Is there a way I can completely turn off the sensor? Also, does the Body-presence use the HR sensor to determine whether or not the watch is on the body?

I'm trying to make a clockface specific to low light environments; Photographic darkrooms in particular (yea, not too many of us left using those, but that's beside the point). Due to the flashing green light on the optical HR sensor, I can't use my Versa in my darkroom (small amounts of red light are okay, blue/green light even in very small amounts is very bad). I expect there are other situations (astronomy?) where the ability to black-out the watch would be beneficial.

Have a look in the 'Settings' app on your watch. I don't think you can control this via API.

Turning off the HR in the watch settings does not disable the light / optical sensor.

I am hoping to make turning off the light a one button press process, so while that would be better than nothing, I'd still prefer to disable the sensor via API.

give it enough time they will stop working on their own.  Fitbit sucks
