I just started trying out Gadgetbridge a couple of hours ago, with the goal of tracking my heart-rate during sleep. However, Gadgetbridge reports heart-rate and activity values while I am not wearing my watch. It is on a stand on my table.
Attached is a screenshot of Gadgetbridge's activity window for the time that the watch is untouched on its stand. As you can see, it shows relatively convincing heart-rate values… for the slate of plastic that it is measuring…
If I go into the Health app, it also shows hourly averages that match the data in Gadgetbridge. It has hourly average heart-rate for hours where the app wasn't worn and just sat on its stand.
What is the deal with this? Does the bangle.js 2 just make up heart-rate values if it thinks that it is worn but cannot measure anything?
