      i Started having a very strange issue when adding zonesense on my S+ app of the watch:

      The watch does not recognise the H10 belt on the activation screen (it shows the normal heart and not the heart with the belt). Deactivating the OHR causes the watch to try to find a belt without any success. (removing the belt, resetting the watch etc makes no difference). Then by removing the S+ from the watch temporarily fixes the situation

      Anyone else on that ?

        @thanasis Have you tried pairing the HR belt in the watch settings? If it finds the belt? Just guessing 🙂

            Third race with ZoneSense.

            The first two went ok, although one of them gave completely different results on watch and on app, but as far as I understand it, it’s normal.

            On the third one hour easy run, 10 minutes without results (normal) and the rest of the time always green.
            But on watch -> nothing.

            I understand it’s growing pains. I’m just giving another testimony to add to the KB.

              Hi @martintrail . Yes, it is and was there for quite some time but i also did it again.

              it seems to have an issue only when install the S+ app on to excercise

                I’m having the feeling zonesense is too aerobic for my fitness level:

                I would have expected ot to be more yellow?

                  @dmcdmc hi, green and BLUE? Are you sure you are checking ZS data on the SA? If I am not mistaken ZS has only three color - green, yellow, red.

                    @claudiotereso another run with zonesense on the watch and no zonesense on the app.
                    Just reseted the watch, let’s see if it solves…

                      and … the heart rate on suunto app is ok, but for strava the first 10 minutes are flat.
                      Is it me, or this zonesense thing still needs a lot of work ?:P

                          @claudiotereso @chee-ee-jordan-lo You should read the information or watch the videos before posting. The DDFA values require 10-15 min to establish baselines so values will not show. From an actual beta tester….

                            @Brad_Olwin you should read the thread more carefully. The original issue he was talking about was the zonesense not working in the suunto app. Which is what im referencing.

                              I don’t recognize the problems some folks seem to be having. It’s been working great so far and really looking forward to more workouts with the belt 🙂

                                @Brad_Olwin I know that DDFA doesn’t have values in the first 10 minutes.
                                But i am showing is the heart rate. The heart rate is always counted.

                                On suunto App I have all the heart rate correct from the beginning and no zonesense info, but when exported to strava we lost the first 10 minutes of heart rate that, as far as I understand, is independent from zonesense.
                                the export mixed them …

                                UPDATE!
                                There is another screen on suunto app that doesn’t show the first 10 minutes of Heart Rate

                                😛

                                Does this makes sense?

                                  Maybe worth opening a separate post for such bugs, it begins to be a mess 😊.
                                  And on my android app, first 10min of HR are there for last run even with ZS

                                    @Mff73 I am extremely dubious about Zonesense.

                                    The data seems to be mostly garbage sadly.

                                    I have done 6 or 7 runs with it now and it seems to lack credibility.

                                    The anaerobic threshold calculation is clearly nonsense!

                                      @cumbrian-runner Hard to say, are you sure your heartrate zones are correct? Or was it really such a hard run, mainly vo2max?

                                        @cumbrian-runner Hmm, I agree with @VoiGAS. You might want to have a look at your HR zones. It is of course possible to run for ~16 minutes in Z5, but you would probably be completely gassed at that point. Z5 is usually your all-out sprint HR. And your settings for Z2 through Z4 are pretty narrow.

                                        You reached 178 bpm during that workout, which is above your max HR setting of 175. For me, I almost never reach my max HR, maybe once a year. Even then, I set my max HR a few beats higher knowing I could potentially go a little harder.

                                        So if your max HR is closer to 180+, then the ZS measured anaerobic threshold of 171 makes some sense. Your setting of 152 looks low to me. These are just the observations of a stranger across the Internet.

                                            @VoiGAS Yes, based on my MaxHR which is correct within they are correct. I cannot sustain 175 by more than 5 seconds, anything over is literally a 1 second reading.

                                            I am in my mid 50s and have tracked its decline from 183mm over the last few years.

                                            It wasn’t really a hard run. Its less than 5 miles with about 20% of my usual elevation profile. Typical runs are 3x longer at similar HR.

                                            (Average hr was 78% of max)
