bogus heart rate values
#1
When I turn on heart rate monitor, the displayed rate constantly varies across a wide range of numbers, and it's not just me (so I don't need an emergency hospital visit) but others I know have tried this watch and get wildly varying results 

180
147
150
96
87
174
140
164
147
80
213
169
123
160
122
139
185

Is this known to not work?

Which software are you using? I don't think it's reliable yet with either InfiniTime 1.3 or with Wasp-OS. The former is from practical experience - it's not too bad IF you both get the strap tension just right, and keep your wrist still. I get the impression it's similar with Wasp-OS from one of the other threads , but haven't tried it. It does have the option of recording the raw sensor data and downloading it so someone sufficiently motivated can improve on the relatively simplistic algorithm.
