        You’re using a 9 Peak Pro as well? What firmware you’re on? My watch is on firmware 2.50.28

          Same firmware, it is the last available. I was doing some testing and I will repeat today and get back here on my results.

            Also using a 9PP with the latest firmware and the original Suunto Smart HR Belt. I do not have (all?) those issues, sometimes it looses connection but the graphs look fine as far as I can tell. But I also will watch this and see if anything weird occurs.

              @Pyranya Here is the example from my run, a 20 min walk today was fine as well. V2 and S9PP paired to SHRM2

              Walk with Run 2 OHR and S9PP with SmartSensor, these don’t match as well as I would have expected.

                I’m not sure, but you can see from the graph that there’s a regular drop in heart rate at that point. It seems to me that this happens every time the connection is lost.

                During this run, I made sure to maintain a consistent pace throughout. The first 5 minutes and the last 5 minutes were slower than the 20 minutes in between.

                  @Pyranya have you checked the R-R plot of your heart rate data? The strap may be not working anymore, and that is not fixed by changing a battery.

                    Where do I find the R-R plot of my HR data?

                      @Pyranya it is not in Suunto App. Export your file to an external service, such as Runalyze or quantified-self.io and check it there. If it is very noisy, then there is some issue with your strap.

                        Used Runalyze:

                        It seems to look very noisy.

                          it looks ok at the beginning, then it goes bananas 🙂

                            Duration for the run was 30min.
