The list of devices here does not seem up to date:
To be clear, there are two uses for Smartwatches:
a) with the locus addon, so that the smartwatch can display certain things from Locus
b) for heart rate monitoring going directly into Locus app via either ANT+ or Bluetooth
I am interested in the second option, and for bluetooth.
My phone does not have ANT+.
a) Do Garmin watches also work for HR monitoring with Bluetooth? In the link above, Garmin are only listed under ANT+.
a) do the recent Amazfit watches work via bluetooth for HR monitoring? There is only one listed in that list, the Amazfit BIP. What other models also work?
b) the Xiaomi Mi Bands are listed but only 3,4,5. Does 6 also work?
