I noticed my Fitbit Versa has one LED and my Charge 2 has 2 LEDs. I imagine the more LEDs the more accurately the device is able to read. I’m not sure. Does anyone have any ideas?

@MrJohn312 Versa has 2 LEDs. One is red and one is green. I've noticed only the green on during the day and only the red when I wake up and look at it in the middle of the night. First thing in the AM, as I'm waking up, the red and green flash together. I read elsewhere on these forums that the red helps calculate resting heartrate.
