      Hi everyone

      Since the new firmware update the heart rate monitoring has been a bit broken.

      Yesterday the heart rate was stuck between 70 - 80 bpm for 10min then suddenly snapped back to expected ranges:

      Has anyone experienced this?

            @Anrich-Potgieter Same here.
            I use an HRMstrap when running, but not on the Rowingmachine.

              Same here, first activity with new firmware. First 11 minutes of OHR reading is incorrect. I had same pace from begining on closed lap. My HR was higher from beggining. Between 30-40min lower HR is fine as i went slower in that part.

              But i experienced something like that rarely with old firmware too.

                Came here to see if anyone else was seeing this. Had a few workouts and suspected this but on a new programming and 2nd guessing. Today, I wore this and bicep strap with AmazFit app sync. WILDLY different results for the first 10 mins or so.

                First 3 mins or so is a warmup and expected the lower rates there, but after an initial spike, you see the strap lock on at least 5 mins sooner to my cadence.

                  I have a similarly suspicious HR output from a pool swim yesterday.

                    Another two workouts with very broken HR, the HR is locked until my first rest, then begins to climb.

                      @Anrich-Potgieter Ok. I did a repeat of the same workout with the Vert 2 instead of my Race 2 and was back within normal ranges of the bicep strap. Not sure if this is something just with the Race 2 update as they supposedly share the same sensors. I’ll keep testing.

                        @dimitrios-kanellopoulos @pavel.samokha is there any known issue to suunto with HR too low for around first 10 minutes of excercise with latest firmwareon Race2 ?

                          I have a similar problem with my Race and Polar H10, where it gets stuck at 70-80bpm sometimes.

                            I had the same issue yesterday and today the heart monitor stopped working. After a hard reset, the HM came back and it is not working

                              I recently got a Vertical 2 and today I did a comparison with a chest strap on the indoor trainer. I am coming from a Garmin Instinct, which always underread my heart rate so much that it was useless. I was very disappointed when I looked at the Vertical 2 during warm-up, where I was already breathing harder and the watch only gave me around 80 bpm, which is what I usually have for an easy walking pace on the flat. I started thinking that there is something wrong with my blood flow because it also doesn’t work! After 10 minutes give or take it was however spot on and matched the strap even up to a heart rate approaching 180 bpm.

                                @Daniel-Thomas cycling is always hit or miss due to arm tension/grip etc. Frequently discussed here.

                                  Hi everyone.

                                  I got the very same issue as the others. Interestingly enough I bought the watch this week on Monday, did a setup, firmware update, and literally every activity has wrong HR readings.

                                  The watch is struggling during first minutes during activities but that’s not all.

                                  I was thinking ok, there is cold outside or smth and that’s why the HR is not quite catched , but no, even running at home for couple of minutes seems a struggle for the watch.

                                  Btw. when I don’t do any activity and then let’s say I’ll quickly climb some stairs to the point where normally my arm band is showing up 130-140 and I am feeling tired, the watch is showing up 90-100 which is so weird.

                                  I am thinking of returning it, as I still have an opportunity to do so.
                                  I’ll try to reset the watch again, but I don’t expect any fireworks.

                                    @piotras I see poor HR too

                                    Can’t comment on earlier firmware as watch updated itself out of the box

                                      @cumbrian-runner hi, yeah, I have the newest firmware as well.

                                      I did a hard reset and did a 5km test run, and compared the activity with my old garmin forerunner 255 + polar verity sense arm band.

                                      Looks much better now, there are some wobbles here and there (like showing up 10bpm higher in around 18minutes), but overall it is pretty good (162 to 163 bpm average).

                                      My 5km run:

                                      Climbing the stairs still not quite good, the HR is updated to proper values only after i stop for a while, and yes I had the watch pretty tight on my wrist and a bit above the bone.

                                      And to indicate what was going on before hard reset, one of my walks:

                                        @piotras I tried a factory reset as well, and did get better. Still odd that the Vertical 2 is still more consistent for me across the board with same sensors.

                                          Hello,

                                          Have the same problem, HR stuck at 110 BPM during the first 20 minutes of running, then suddenly goes up to 165 bpm which is the correct reading. It was working better before the last firmware.
